NSS3000 Performance vs 6000
The 6000 series had well documented performance issues with a reported throughput of only 15M. Does the 3000 improve upon this or does it perform the same or worse than the 6000?
Glenn,
I already found some 3rd party documentation that indicates that the performance is about the same as the 6000. Max of about 15 - 20M

K9A2 Neo + AMD X2 6000+ performance problem
Hello!
I got this problem wich i wonder if it has to do with the chipset contra graphic card.
I used to have an AMD X2 3800+, ASUS A8N5X NFORCE4 mobo, 2gb PC3200 400mhz, and i exchange those for AMD X2 6000+, MSI K9A2 Neo, 2gb Corsair XMS2 800mhz. My graphics card is a NVIDIA GF8000GTS running under Win XP 32.
My problem comes down to that this new gear runs like my older. If not worse at times. And my friend that has an identical system can play on very high settings without any stutter while i have to play on normal. Exactlly as my older system. The difference we have is that he is using a NFORCE motherboard. Im now wondering if that has such an impact on performance? Having a NVIDIA graphics card and use this MSI with ATI chipset.
When i baught it today i asked for NFORCE but i guess he forgot after picking it up and handing it to me, and i ofcourse forgot to double check. I thaught it was NFORCE7 when i saw the "770" marking. I also installed some AMD CPU DRIVERS that came with the disc. Dont know what they are for. Never seen that before. I also skipped installing the "ATI SYSTEM DRIVERS" as i figured i dont use ATI graphics card. Dont know if i should?
I will exchange this for a NFORCE mobo, but i just wanted to check with you if this really can have such impact on performance.
I have everyhing else updated to latest drivers with XP SP3 up to date.
Hope for some answer. Thank you in advance.
Regards
AlexMy friend and i got the same gear apart from the nforce mobo.
I got a 500W PSU and it should do as antother friend of mine got 600W and running SLI and faster CPU, more RAM etc. When i installed this i ofcourse formatted and made a fresh install. Unless you mean that i need to install the ATI SYSTEM DRIVERS first? I dont know if its 30 AMPS on the PSU though. Need to check that.
To me it just sounds more sain to use Nvidia chipset together with Nvidia graphics card, and ATI chipset with ATI graphics. But as you say you got no performance probs with that i might be wrong. However i am comparing to a friend with the same gear and playing online at the same time. He can go way up in settings i cant. I even stutter on the normal settings, and he doesnt on the high settings.
Gotta check the 30AMPS now.
Thanks for your ideas. Your probably right. Will check.

Lack of performance in SELECT-ing XML records
Hello Champs, I am new to XML world. But as a DBA now I'm into the situation to suggest better performance improvement in accessing XML records.
Problem:
There is a batch job from informatica, fetching records from XML tables(close to 400, one by one) stored in oracle database. All 400 tables just have two columns as described below:
Name Null? Type
RECID NOT NULL VARCHAR2(255)
XMLRECORD XMLTYPE
Each table has NORMAL index created for it only for VARCHAR2 column:
CREATE UNIQUE INDEX "username"."Indexname_PK" ON "username"."table_name" ("RECID") PCTFREE 10 INITRANS 2 MAXTRANS 255 NOLOGGING COMPUTE STATISTICS STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT) TABLESPACE "tbs_idx" ;
All the table has the CLOB index created for it with below description.
CHUNK PCTVERSION RETENTION FREEPOOLS CACHE IN_ROW FORMAT PAR
8192 14400 YES YES ENDIAN NEUTRAL NO
Informatica issues below query on all the table, where it could just fetch only 400rows/sec in average. This takes entire buisness day to complete the batch job for all 400 tables, which gives big problem in production environment.
SELECT <table_name>.<column_name>.getclobval() FROM <table_name>;
SQL> select * from v$version;

Clarification required:
1. Where do you see in this scenario, there is a problem which blocks the performance?
2. What type of index on this setup is normally advisable?
Many Thanks for your assistance,Not sure if you will like it, although it will improve your performance issues considerably, upgrade to Oracle 11.2.0.3 or 11.2.0.4 and be sure that all those XMLTYPE (CLOB) stored columns will be created/recreated with XMLTYPE (SECUREFILE BINARY XML).
One way of making sure that XMLTYPE will be stored via Binary XML Securefile LOB storage is by setting "db_securefile" on database level ( Using Oracle SecureFiles ) to value ALWAYS or FORCE. Binary XML Securefile XMLType content may only be created on ASSM enabled tablespaces... -
Looking for help to increase performance on a DB XML database.
I'll try to answer all the questions in the Performance Questionnaire from here.
1) I'm primarily concerned with insertion performance. The best I've seen so far is about 6000 inserts/per second. This is running inside a VMWare VM with 3 GB of RAM. The VM is set up with 2 CPUs each with 2 cores. The host machine has 8GB of RAM with a dual core 2.67 GHZ i7 (2 logical cores per CPU). The best performance I've seen is by running 2 threads of execution. A single thread only gets me about 2500 inserts per/second.
This is all within a very simple, isolate program. I'm trying to determine how to re-architect a more complicated system, but if I can't hope to hit 10k inserts per second with my sample, I don't see how it's possible to expand this out to something more complicated.
2) Versions: BDBXML version 2.5.26 no special patches or config options
3) BDB version 4.8.26, no special patches
4) 2.67 dual core, hyperthreaded intel i7 (4 logical processors)
5) Host: Windows 7 64-bit, Guest: RHEL5 64-bit
6) Underlying disk is a 320GB WesternDigital barricuda (SATA). It's a laptop harddrive, I believe it's only 5400 RPM. Although the VM does not have exclusive access to the drive, it is not the same drive as the Host sytem drive. (i.e. Windows runs off of the C drive, this is the D drive). The has a 60GB slice of this drive.
7) Drive is NTFS formatted for the host. Guest, ext3
8) Host 8gb, guest 3gb (total usage when running tests low, i.e. no swapping by guest or host)
9) not currently using any replication
10) Not using remote filesystem
11) db_cv_mutex=POSIX/pthreads/library/x86_64/gcc-assembly
12) Using the C++ API for DBXML, and the C API for BDB
using gcc/g++ version 4.1.2
13) not using app server or web server
14) flags to 'DB_ENV->open()': | DB_SYSTEM_MEM
| DB_INIT_MPOOL
| DB_INIT_LOCK
| DB_INIT_LOG
| DB_INIT_TXN
| DB_RECOVER
| DB_THREAD
other env flags explicitly set:
DB_LOG_IN_MEMORY 1
DB_LOG_ZERO 1
set_cachesize(env, 1, 0, 1) // 1GB cache in single block
DB_TXN_NOSYNC 1
DB_TXN_WRITE_NOSYNC 1
I am not using a DB_CONFIG file at this time.
15) For the container config:
transactional true
transactionsNotDurable true
containertype wholedoc
indexNodes Off
pagesize 4096
16) In my little test program, I have a single container.
16.1) flags are the same as listed above.
16.2) I've tried with an empty container, and one with documents already inside and haven't noticed much difference at this point. I'm running 1, 2, 3, or 4 threads, each inserting 10k documents in a loop. Each insert is a single transaction.
16.3) Wholedoc (tried both node & wholedoc, I believe wholedoc was slightly faster).
16.4) The best performance I've seen is with a smaller document that is about 500 bytes.
16.5) I'm not currently using any document data.
17)sample document:
<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<Record xmlns='http://someurl.com/test' JID='UUID-f9032e9c-7e9a-4f2c-b40e-621b0e66c47f'>
<DataType>journal</DataType>

<User name='root'>0</User>
<SecurityLabel>unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023</SecurityLabel>
</Record>
18. As mentioned, I'm looked to get at least 10k documents per second for insertion. Updates are much more infrequent, and can run slower. I am not doing any partial updates, or replacing documents. In the actual system, there are minor updates that happen to document metadata, but again, these can be slower.
19. I'm primarily concerned with insertion rate, not query.
20. Xquery samples are not applicable at the moment.
21. I am using transactions, no special flags aside from setting them all to 'not durable'
22. Log files are currently stored on the same disk as the database.
23. I'm not using AUTO_COMMIT
24. I don't believe there are any non-transactional operations
25. best performance from 2 threads doing insertions
26. The primary way I've been testing performance is by using the 'clock_gettime(CLOCK_REALTIME)' calls inside my test program. The test program spawns 1 or more threads, each thread inserts 10k documents. The main thread waits for all the threads to complete, then exits. I'm happy to send the source code for this program if that would be helpful.
27. As mentioned, I'm hoping to get at least 10k inserts per second.

=================== -
Interested by performance issue ? Read this ! If you can explain, you're a master Jedi !
This is the question we will try to answer...
What si the bottle neck (hardware) of Adobe Premiere Pro CS6
I used PPBM5 as a benchmark testing template.
All the data and log as been collected using performance counter
First of all, describe my computer...
Operating System
Microsoft Windows 8 Pro 64-bit
CPU
Intel Xeon E5 2687W @ 3.10GHz
Sandy Bridge-EP/EX 32nm Technology
RAM
Corsair Dominator Platinum 64.0 GB DDR3
Motherboard
EVGA Corporation Classified SR-X
Graphics
PNY Nvidia Quadro 6000
EVGA Nvidia GTX 680 // Yes, I created bench stats for both card
Hard Drives
16.0GB Romex RAMDISK (RAID)
556GB LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed (RAID 0)
I have other RAID installed, but not relevant for the present post...
PSU
Cosair 1000 Watts
After many days of tests, I wanna share my results with community and comment them.
CPU Introduction
I tested my cpu and pushed it at maximum speed to understand where is the limit, can I reach this limit and I've logged precisely all result in graph (See pictures 1).
Intro : I tested my E5-XEON 2687W (8 Cores Hyperthread - 16 threads) to know if programs can use the maximum of it. I used Prime 95 to get the result. // I know this seem to be ordinary, but you will understand soon...
The result : Yes, I can get 100% of my CPU with 1 program using 20 threads in parallel. The CPU gives everything it can !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test...
(picture 1)
Disk Introduction
I tested my disk and pushed it at maximum speed to understand where is the limit and I've logged precisely all result in graph (See pictures 2).
Intro : I tested my RAID 0 556GB (LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed) to know if I can reach the maximum % disk usage (0% idle Time)
The result : As you can see in picture 2, yes, I can get the max of my drive at ~ 1.2 Gb/sec read/write steady !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test to see the impact of transfering many Go of data during ~10 sec...
(picture 2)
Now, I know my limits ! It's time to enter deeper in the subject !
PPBM5 (H.264) Result
I rendered the sequence (H.264) using Adobe Media Encoder.
The result :
My CPU is not used at 100%, the turn around 50%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate seem to be a wave (up and down). Probably caused by (Encrypt time.... write.... Encrypt time.... write...) // It's ok, ~5Mb/sec during transfert rate !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 39 Go RAM free after the test ! // Excellent
~65 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card seem to be a wave also ! (up and down) ~40% usage of GPU during the process of encoding.
GPU Ram get 1.2Go of RAM (But with GTX 680, no problem and Quadro 6000 with 6 GB RAM, no problem !)
Comment/Question : CPU is free (50%), disks are free (99%), GPU is free (60%), RAM is free (62%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
Other : Quadro 6000 & GTX 680 gives the same result !
(picture 3)
PPBM5 (Disk Test) Result (RAID LSI)
I rendered the sequence (Disk Test) using Adobe Media Encoder on my RAID 0 LSI disk.
The result :
My CPU is not used at 100%
My Disk wave and wave again, but far far from the limit !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Buffering time.... write.... Buffering time.... write...) // It's ok, ~375Mb/sec peak during transfert rate ! Easy !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40.5 Go RAM free after the test ! // Excellent
~48 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card = 0 (This kind of encoding is GPU irrelevant)
GPU Ram get 400Mb of RAM (No usage for encoding)
Comment/Question : CPU is free (65%), disks are free (60%), GPU is free (100%), RAM is free (63%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
(picture 4)
PPBM5 (Disk Test) Result (Direct in RAMDrive)
I rendered the same sequence (Disk Test) using Adobe Media Encoder directly in my RamDrive
Comment/Question : Look at the transfert rate under (picture 5). It's exactly the same speed than with my RAID 0 LSI controller. Impossible ! Look in the same picture the transfert rate I can reach with the ramdrive (> 3.0 Gb/sec steady) and I don't go under 30% of disk usage. CPU is idle (70%), Disk is idle (100%), GPU is idle (100%) and RAM is free (63%). // This kind of results let me REALLY confused. It's smell bug and big problem with hardware and IO usage in CS6 !

PPBM5 (MPEG-DVD) Result
I rendered the sequence (MPEG-DVD) using Adobe Media Encoder.
The result :
My CPU is not used at 100%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Encoding time.... write.... Encoding time.... write...) // It's ok, ~2Mb/sec during transfert rate ! Real Joke !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40 Go RAM free after the test ! // Excellent
~80 thread opened by Adobe Media Encoder (Lot of thread, but it's ok in multi-thread apps!)
GPU Load on card = 100 (This use the maximum of my GPU)
GPU Ram get 1Gb of RAM
Comment/Question : CPU is free (70%), disks are free (98%), GPU is loaded (MAX), RAM is free (63%), my computer is pushed at limit during the encoding process for GPU only. Now, for this kind of encoding, the speed limit is affected by the slower IO (Video Card GPU)
Other : Quadro 6000 is slower than GTX 680 for this kind of encoding (~20 s slower than GTX).

Encoding single clip FULL HD AVCHD to H.264 Result (Premiere Pro CS6)
You can look the result in the picture.
Comment/Question : CPU is free (55%), disks are free (99%), GPU is free (90%), RAM is free (65%), my computer is not pushed at limit during the encoding process. Why ???? Adobe Premiere seem to have some bug with thread management. My hardware is idle ! I understand AVCHD can be very difficult to decode, but where is the waste ? My computer want, but the software not !

Render composition using 3D Raytracer in After Effects CS6
You can look the result in the picture.
Comment : GPU seems to be the bottle neck when using After Effects. CPU is free (99%), Disks are free (98%), Memory is free (60%) and it depend of the setting and type of project.
Other : Quadro 6000 & GTX 680 gives the same result in time for rendering the composition.

Conclusion
There is nothing you can do (I thing) with CS6 to get better performance actually. GTX 680 is the best (Consumer grade card) and the Quadro 6000 is the best (Profressional card). Both of card give really similar result (I will probably return my GTX 680 since I not really get any better performance). I not used Tesla card with my Quadro, but actually, both, Premiere Pro & After Effects doesn't use multi GPU. I tried to used both card together (GTX & Quadro), but After Effects gives priority to the slower card (In this case, the GTX 680)
Premiere Pro, I'm speechless ! Premiere Pro is not able to get max performance of my computer. Not just 10% or 20%, but average 60%. I'm a programmor, multi-threadling apps are difficult to manage and I can understand Adobe's programmor. But actually, if anybody have comment about this post, tricks or any kind of solution, you can comment this post. It's seem to be a bug...
Thank you.Patrick,
I can't explain everything, but let me give you some background as I understand it.
The first issue is that CS6 has a far less efficient internal buffering or caching system than CS5/5.5. That is why the MPEG encoding in CS6 is roughly 2-3 times slower than the same test with CS5. There is some 'under-the-hood' processing going on that causes this significant performance loss.
The second issue is that AME does not handle regular memory and inter-process memory very well. I have described this here: Latest News
As to your test results, there are some other noteworthy things to mention. 3D Ray tracing in AE is not very good in using all CUDA cores. In fact it is lousy, it only uses very few cores and the threading is pretty bad and does not use the video card's capabilities effectively. Whether that is a driver issue with nVidia or an Adobe issue, I don't know, but whichever way you turn it, the end result is disappointing.
The overhead AME carries in our tests is something we are looking into and the next test will only use direct export and no longer the AME queue, to avoid some of the problems you saw. That entails other problems for us, since we lose the capability to check encoding logs, but a solution is in the works.
You see very low GPU usage during the H.264 test, since there are only very few accelerated parts in the timeline, in contrast to the MPEG2-DVD test, where there is rescaling going on and that is CUDA accelerated. The disk I/O test suffers from the problems mentioned above and is the reason that my own Disk I/O results are only 33 seconds with the current test, but when I extend the duration of that timeline to 3 hours, the direct export method gives me 22 seconds, although the amount of data to be written, 37,092 MB has increased threefold. An effective write speed of 1,686 MB/s.
There are a number of performance issues with CS6 that Adobe is aware of, but whether they can be solved and in what time, I haven't the faintest idea.
Just my $ 0.02 -
Hello ,
we are currently experiencing heavy I/O problmes perfoming prrof of concept
testig for one of our customers. Our setup is as follows:
HP ProLiant DL380 with 24GB Ram and 8 15k 72GB SAS drives
An HP P400 Raid controller with 256MB cache in RAID0 mode was used.
Win 2k8r2 was installed on c (a physical Drive) and the database on E
(= two physical drives in RAID0 128k Strip Size)
With the remaining 5 drives read and write tests were performed using raid 0 with variing number of drives.
I/O performance, as measured with ATTO Disk benchmark, increased as expected linear with the number of drives used.
We expected to see this increased performance in the database, too and performed the following tests:
- with 3 different tables the full table scan (FTS) (Hint: /*+ FULL (s) NOCACHE (s) */)
- a CTAS statement.
The system was used exclusively for testing.
The used tables:
Table 1: 312 col, 12,248 MB, 11,138,561 rows, avg len 621 bytes
Table 2: 159 col, 4288 MB, 5,441,171 rows, avg len 529 bytes
Table 3: 118 col, 360MB, 820,259 rows, avg len 266 bytes
The FTS has improved as expected. With 5 physical drives in a RAID0, a performance of
420MB/s was achieved.
In the write test on the other hand we were not able to archieve any improvement.
The CTAS statement always works with about 5000 - 6000 BLOCK/s (80MB/s)
But when we tried running several CTAS statements in different sessions, the overall speed increased as expected.
Further tests showed that the write speed seems to depend also on the number of columns. 80MB/s were only
possible with Tables 2 and 3. With Table 1, however only 30MB/s were measured.
Is this maybe just an incorrectly set parameter?
What we already tried:
- change the number of db_writer_processes 4 and then to 8
- Manual configuration of PGA and SGA size
- setting DB_BLOCK_SIZE to 16k
- FILESYSTEMIO_OPTIONS set to setall
- checking that Resource Manager are really disabled
Thanks for any help.

The CTAS statement always works with about 5000 - 6000 BLOCK/s (80MB/s)
But when we tried running several CTAS statements in different sessions, the overall speed increased as expected.
Further tests showed that the write speed seems to depend also on the number of columns. 80MB/s were only
possible with Tables 2 and 3. With Table 1, however only 30MB/s were measured.
If multiple CTAS can produce higher throughput on writes this tells you that it is the production of the data that is the limit, not the writing. Notice in your example that nearly 75% of the time of the CTAS as CPU, not I/O.
The thing about number of columns is that table 1 has exceeded the critical 254 limit - this means Oracle has chained all the rows internally into two pieces; this introduces lots of extra CPU-intensive operations (consistent gets, table access by rowid, heap block compress) so that the CPU time could have gone up significantly, resulting in a lower throughput that you are interpreting as a write problem.
One other thought - if you are currently doing CTAS by "create as select from {real SAP table}" there may be other side effects that you're not going to see. I would do "create test clone of real SAP table", then "create as select from clone" to try and eliminate any such anomalies.

Performance Degradation of new Servers
Hi All,
We are experiencing massive performance degradation on production when the system is under heavy use. It seems to be at its worst around month end. The worst effected transactions are the Cost / Profit centre 'line item' reports using RCOPCA02 (and other similar programs).
We have the message server running on the database instance as well as 2x App servers. The Msg Srv and One of the App servers are very similar builds
4x AMD Opteron 875
16gb RAM (10gb Pagefile)
Both running Win Server 2003
We're using MS SQL 2000
The other message server is a bit weaker but has been around for some time (few years) and hasn't caused any issues.
We have recently moved the Msg Server from an old (much weaker) server to the new build and since then seem to have performance issues. Initially after the move we had issues with the number of Page Table Entries (where down at about 6000-8000). Using the /3GB /USERVA=2900 switches we have this up to about 49,000.
If anyone has had a similar experience or could offer some assistance it would be much appreciated!!!
Cheers,
KyeWhile investigating a different issue we've found that we have 3 servers that share the same set of disks on the SAN. Two of these where Message Servers (R/3 and BW) when both of these where running the 'Average disk queue Length' was at times reaching 400! (should be around 1-3).
We've moved one of these instances back to DR which has relieved some of the pressure from the disks.
We have also added another index to the GLPCA table (which was causing most of the problems). -
FX-55 and NEO2-FIR and poor performance
I just upgraded froma NEO-FIS2R using a Athlon 64 3200+ to a NEO2-FIR and a FX-55.
I got it all working - only after finding out that the Promise controller isn't compatiible with the old Promise controller on the NEO2-FIR.
First thing I did was do some benching - I spent over $1000 for the FX-55 and NEO2-FIR and was hoping to see some significant performance improvement.
Unfortuneately I don't see it. I've loaded the Performance options in the BIOS, made sure that DRAM settings were SPD (I have Mushkin Black LevelII DDR3500 matched dimms - supposed to do 2-2-2-5)
Any advice at all? I'm getting less than 5000 in 3DMark05 - and other like systems are over 6000.
If I go too agressive on memory timing the system is really unstable.
Are there known issues with the FX-55 and the NEO2-FIR? Are there any rec'ds?
Thanks.

Windows XP SP2Have you run any program to test the cpu at 100% like super PI or the like?
People just dont understand 3Dmark is a Graphics benchmark and a synthetic one at that. CPU tests in 3dmark account for so little and there are so many variables that can affect the test like drivers, OS, BIOS settings, programs in the background that I dont consider 3dmark a worthy benchmark for machine power except for GPU performance.
Use something else like SUper PI, or Sandra, to see how much Horseporwer your machine really has.

Poor Performance with my new System
Hi All,
Great Forum. Hopefully someone here can provide me some direction. I just built my first AMD based system (spec's below). Everything is running smooth and stable, but I dont believe I am getting the performance out of this rig as I should. Specifically, I am getting very low scores on 3Dmark05 (5100 - 5300) with my rig at stock settings.
I've surfed through these forums for days and found many folks getting much better performance out of components that are not as robust as mine. So, I am looking for some guidance. So far, Here's what I've done:
1: Bios: I've disabled the "smart & cool"
all of the "aggressive timings" are disabled
Video is selected to AGP (128mg since that's what the BFG Technician recommended for the 256mg GPU's)
boosted video voltage to 1.6v
Manually set all of the ram timings (listed below in the system description)
Processor HT is set to 5x (i got this from the AMD site)
most of the other settings are set to auto.
2: Temps: The CPU is currently idling around 42 degrees. 46 under load
The GPU is idling around 62 degrees. this seems a bit high, but i havent been able to verify.
3: CPU Scores in 3DMark05 are in the mid-high 6000's
Ive also tried to load the registry oc program for the GPU (from guru) and it only made things worse. standard clock settings (factory oc'd) work best. The system is extremely stable and runs quite smoothly. It's very quiet and cool (42-46 cpu, 34 ambient)
I am not sure where I went wrong here, but something is just not making sense. I've read posts where folks are getting scores in the 10's and 11's with lesser processor and GPU gear. Any directions here would be greatly appreciated. Hopefully i've posted enough information. Thanks for your help!
MB: MSI K8N Neo Platinum
Award BIOS, v1.8
PROC: AMD Athlon 64 4800+ (42 degrees idle, 46 degrees loaded)
MEM: 2x Corsair TwinX-3200C2-Pro (2.5, 3, 3, 6, 1T @ 2.7 volts)
GPU: BFG GeForce 6800GT OC 256MB AGP, nVidia v78.01
PSU: UltraX-Connect 500W
HD: WD Raptor 74G 10,000 rpm
CD: Plextor DVD-R/W
FAN/HS: XP-90 e/w SilentCat fan (yes, it fits with the memory in slots 3&4. No problems with this with the new bios. All is stable and runs well)
Windows XP SP2Thanks for the replys guys.
I did read a few threads where folks were boasting numbers in the 10's and 11's. From your notes, it appears that they were simply blowing smoke. I appreciate knowing that, although I dont understand the purpose of posting inaccurate information in these forums. These are (and will continue to be) and excellent resource unless they become clogged with garbage.
As far as temperatures on the GPU, I figured it was a bit high, but according to BFG, it's good to 120C (that seems way outta line). i imagine that i would get a bit better performance from it by replacing the stock heatsink/fan combo with an aftermarket GPU cooler from Zalman. The right thing to do is to replace my MB with a ASUS SLI-Premium and put a couple of 6800 Ultra's in it (lol).
I appreciate the information. It appears that i have achieved the maximum from my PC, and as I stated before, it runs great. Thanks again for the help guys. If I get rich and decide to change out the guts for an SLI set up, I'll let you know. Until then, I think i'll grab a GPU cooler and see if I can get the temps down a bit.
Is there any benifit to removing the stock Heatsink/Fan and trying some Artic Silver 5 in there? I've heard a few folks have gotten some decent results doing that.
Thanks again

Adding items to custom list - performance issues - Request timed out error
Hi,
I am using VS 2010, c#.
I am inserting records from an excel file, which contains 6000 records to a custom list.
I am using the Visual webpart, and oledb connection. I am not using the openXML format, as i need to use "xls" and "xlsx" type.
I am doing the below steps currently:
1) From the file upload control, i am saving the excel to the sharepoint layouts - inside that a custom folder, to keep the records.
2) Using the oledb connection to read the records and fill it in a datatable.
3) Inserting the datatable values to a custom list.
Looping through the datatable and inserting 3000 – 4000 records to List, I am getting the "Request timeout error".
Below is the sample code, where i am looping the datatable and inserting the record:
SPList prjCmpList = oWeb.Lists[strListName];
SPListItemCollection prjCmpListItems = prjCmpList.Items;
SPListItem prjCmpListItem;
foreach (DataRow dr in dt.Rows)
try
prjCmpListItem = prjCmpListItems.Add();
prjCmpListItem["Title"] = dr[0];
prjCmpListItem["FirstName"] = dr[1];
prjCmpListItem.Update();
catch (Exception)
I am using the "using block" for the spsite and web objects. When I see the execution time out in my web.config it is set to 3600. But I am getting the request time out after 2 mins only.
I have checked these link's : http://msdn.microsoft.com/en-us/library/aa973248%28v=office.12%29.aspx
http://www.etechplanet.com/blog/how-to-import-an-excel-spreadsheet-in-sharepoint-and-save-it-as-a-custom-list.aspx
http://social.msdn.microsoft.com/Forums/sharepoint/en-US/8664375c-fae0-483a-b43f-ce7d353b896a/importing-3000-records-to-sharepoint-list-causing-requesting-time-out-error?forum=sharepointadminlegacy
However, I am following the best practices, and also the insertion of records is to be done programmatically.
Has anyone faced this kind of issue? How to fix this?HI,
Thanks for the reply.
If the list has custom columns which consists of string and Date types, can the same type be used? Or should the list be an empty list without any columns?
In the xml if it is put as "onerror= continue", how to fetch the records which error out?
Also, in the datatable code block, which I had put in the first post, I am also trying as below:
if(dt[1] != null)
if(!string.IsNullorEmpty(dt[1].toString())
prjCmpListItem["FirstName"] = dt[1].toString();
Can these condition checks be performed with the "processbatchdata" approach?
Thanks -

http://support.apple.com/kb/TS4123?viewlocale=en_US -
First of all, I'd like to ask that you bear with my nubness while I fumble my question out. Hmm... ok.
In anticipation of HL2, I purchased all the parts I needed for a system and built one (my first and only time so far) in September 2003. Having recently come into some money, I kind of went pretty far out. Here are the main system specs, which have remained unchanged since September:
Intel P4 3.00 Ghz
MSI MS-6758 ( the 875P Neo)
Corsair TWINX1024-3200LLPT (2x512)
Turbolink 420 Watt PSU
PNY Geforce FX 5900 Ultra
Creative Soundblaster Audigy Gamer
Western Digital 160 GB HD
Sony CD-RW/DVD-R drive
Sony DVD drive
(XP Home Edition SP1)
Sounds pretty nice, doesn't it? So when I get a 3dMark03 score of 4772 -- less than half of what most people with nearly identical systems got -- and an average framerate of 14 frames per second in Half Life at 1024x768 with no AA or other special junk running, well, I don't know what to think.
The first thing I did was check on all of my drivers. I'm currently running the most recent official drivers for all of my hardware, and framerates are as low as before. So, then I decided to bite the bullet and flash my bios (which was thankfully a lot easier than I had built it up to be), since it was nearly a year out of date. The new and improved bios yielded no performance gains, but then I'm not quite sure if it should have or not. As a nub, the general rule of thumb I follow is "the newer, the better." I realize that it's not always so in some cases, but it's worked well enough for me so far....
So... I'm perplexed. And because I don't know if it's an issue with a single component or anything, it's hard to find answers online. So I bring it up to you to help a nub. Please, if you have any idea what I'm talking about and what I could do to fix it, I would build a 50 foot stone statue of you and name my firstborn whatever you desire.
If you need any clarification, I'll be refreshing this thread all night. Thanks... I hope.Well, thanks for all of the replies. I'm using the patched version of 3dMark03 and the 56.72 Forceware drivers. I should have phrased my question differently. It's still basically the same thing, but the focus isn't the benchmark test -- it's the abysmal framerates in games. I can certainly understand a lower fps in games like Far Cry, but with stuff like Half Life... the computer I used two years ago was doing better than this one. (Has anyone else experienced similar issues?)
And actually, as a matter of fact, this one used to do quite well. I had a giant general f*ck-up, though, and was forced to reformat and basically restart everything from where I began, and I guess this is where the problem came in.
As for OCing, I want to do some more research on that before I potentially kill my system trying to reach the 6000 mark ;o. As it stands, I need to clean a lot of dust out of my PC (my idle temp is 44 C :X) or maybe get a cooler room to put it in. That said, overall system performance has been a good deal better since I installed newer drivers, new bios, etc... it's just not affecting games as much.
And Sandra has been a big help in more ways than I can recount, Aaron, thanks.
Question: What about my video card BIOS? Is that something I should look into updating, or what?
Thanks once more. -
Hard Drive Failure on HP DV 6000 Pavilion laptop (dv6108nr) with Windows-XPsp3 OS - Need Data Recov
Hard Drive Failure on HP DV 6000 Pavilion laptop - Need Data Recovery Help
HP Pavilion DV 6108 NR, RG365UA, purchased in late 2006 at Best Buy, with Windows XP, upgraded to Service Pack 3. It has a Fujitsu hard disk, 60 gigabyte, partitioned into C: and a Recovery D:.
Windows tries to boot up, but goes to blue screen with the message: "Unmountable Boot Volume" for one second, then just keeps recycling until I force a shutdown.
BIOS Phoenix, hard drive test result: " #1-08 Fail "
I ran a disk analysis/recovery program on the Cdrive and it seemed to show the directory structure intact, and it was able to recover some files. I was using the free one from Seagate (which only recovers small files). The second pass didn't run so well, and during the third run the program said I should not proceed further, and I should contact a professional disk recovery company.
However, the D drive seems to be intact, so, I wonder if the disk is corrupted or just some aspect of the logical C drive is bad. Or does the disk have a mechanical failure, in which case, is a recovery disk even helpful at all?
How can I get the D: to run the recovery software on it? The recovery disks, made by Best Buy, only proceed to the R / F / Q option screen, and when I press R, I get a blue screen every time.
Tapping the F10 key during startup gets me nowhere. Ditto the F11 key.
I dont care about the hard disk; it is the data (files, docs, images, etc) that I want.
I contacted HP to order recovery disks but they are no longer available for my computer. (But see below, "UPDATE")
Any suggestions would be greatly appreciated!
Jon
===============================
UPDATE:
I found a website that offers the following:
www.computersurgeons.com/p-13442-recovery-kit-435422-001-for-hp-model-number-dv6108nr.aspx
Recovery Kit 435422-001 For HP Model Number dv6108nr
Price: $27.00
Recovery Kit Set (An Entire Image of the Computer hard drive when the computer was new)
But I wonder how useful it would be. Early XP , no doubt. And if my hard disk problem is a mechanical fault, would any recovery disk even work? The disks made by Best Buy when I bought mine new in 2006 don't do anything more than go to the R /F/ Q screen and then my computer goes to a blank blue screen when I press R (to recover the OS and apps and data files). And, as I wrote, it is the data that I want, not the disk drive.
Any help here would also be appreciated!
JonHi @goshenguy
Thank you for your inquiry, I am happy to help.
I grasp you tested the hard drive from the bios and it failed. This tests the physical aspcects of the hard drive and when it fails it does require replacement. You were able to retrieve some of your files using recovery software but not all.
Your recovery partition is still intact and when you try to do a recovery with the disks from Best Buy you do not get past these options R / F / Q but will not proceed.
Here is a link to Performing an HP System Recovery (Windows XP, 2006 or Later) that may assist you in performing a recovery.
Here is a link to the Maintenance and Service Guide HP Pavilion dv6000 Notebook PC. Please note chapter 3 page 42 for a replacement hard drive part number.
HP Parts, HP Replacement Parts
If you are still unable to do the recovery, you could try contacting Best Buy for assistance with the recovery kit they provide.
I don't know if it is possible, but you may want to check cloning software to see if you could clone the D partion to the new drive or connect both drives and try a drive to drive copy of the D partition.
If you were able to successfully put the D partition on a new hard drive you should be able to do a recovery from the D partition to take it back to factory.
If none of the above has allowed you to successfully do a recovery, I suggest contacting Best Buy to see it they have options other then purchasing a third party recovery kit.
Good Luck!

Hard drive failure on Pavilion dv6-6000 laptop (LT069AV)
I posted this as a reply on another thread (xxx). Thought I might get a quicker response starting a new question.
Persistent BSODs and disk errors culminated in a "disk not found" error yesterday on my dv6-6000 laptop PC. Windows 7 Home, Intel i5 processor, 6GB RAM. I like the PC overall - nice screen and usually great performance. I look forward to getting it back online as it serves as my work as well as personal computer.
So, I need to replace my hard drive and reinstall the OS with a an HP recovery disc that I have yet to purchase (I can't find a recovery disk I produced myself after several moves), and then restore using my cloud backup solution.
The HP part number for the SATA hard drive is 621046-001 (this is a 640 GB volume). I noticed that a replacement for this drive is available at CPU medics for about $90. Would I be foolish to order a replacement, having just experienced a drive failure with this part? Should I look to other manufacturers and perhaps go with a 750 GB volume? Also, do I need to replace with a 7200 rpm drive? Is there any disadvantage if I went with a 5400 rpm HDD?
Any suggestions?
majohaYou have options when installing Windows 7 to create partitions, you could just select the complete space & install as one partion then once installed use windows disc partition manager to adjust it to you requirements.
Windows 7 can be loaded to a memory stick & the link provided includes a tool to make the bootable memory stick.
Plenty of step by step guides on installing windows can be found on google, it is quite easy but first time is always going be slower due to learning curve, if you like super simple then hp recovery discs could be worth the money dor you.
Link below is guide on installing Windows 7, useful as a rough guide on what involved.

The cost is the same because the plan is the same. The optimiser chose to use that index anyway. The point is, now that you have removed it, the optimiser is free to choose other indexes or a full table scan if it wants to.

I can't tell you if there's a better way to write this query or if indeed there is another way to write this query because I don't know what it is attempting to achieve.
I can see that you're accessing 100k rows from a 110k row table and it's using an index to look those rows up. That seems like a job for a full table scan rather than index lookups.
