Poor performance after server port to SUN

Hi all,
porting our C++ corba server to SUN was not very successful, because the performance of the SUN version was 15 times bad then the performance on Windows with the same source code and some reference tests.
I have attached our build options and the configuration of our develepment equipment.
We have done this port also on earlier versions and we see also, that the server was slower, but only the factor 1.5 to 2, so I was wondering why I have such a big difference in this release.
What we have changed between the releases was, that we use the boost libraries (V 1.32) and therefore we compile and link now with stlport4 library. We changed also from Forte 6.2U2 to SunStudio 10.
First I thought, that it is the old development equipment, what make the diffrence, but also our newest available machine (SunOS sudecgn0032 5.10 Generic_118833-23 sun4v sparc SUNW,Sun-Fire-T1000) show the same runtime performance. Any idea? Are there some tools that can help to analyse, if there is perhaps a structural difficulty?
regards
Arno

The programs was ported also in earlier versions 1,5 year ago we use forte 6.2 and the performance was o.k.
Possibly the program design was based on Windows
features that are inappropriate for Unix. So the principal design didn't change, the only thing is, that we switch to the boost libraries, where we use the thread, regex, filesystem and date-time libraries
Have you tried any other Unix-like system? Linux, AIX, HPUX,
etc? If so, how does the performance compare to
Solaris?Not at the moment, because the order is customer driven, but HP and Linux is also an option.
Also consider machine differences. For example, your
old Ultra-80 system at 450Mhz will not keep up with a
modern x86 or x64 system at 3+ GHz. The clock speed
could account for a factor of 6. That was my first thought, but how I have wrote in an earlier post, the performance testcase need the same time on a 6x1GHz (some Sun-Fire-T1000) machine
Also, how much realmemory does the sparc system have? 4 GB! And during the testrun the machine use less than 30% of this memory.
If the program is not multithreaded, the additional
processors on the Ultra-80 won't help. But it is!
If it is multithreaded, the default libthread or libpthread on
Solaris 8 does not give the best performance. You can
link with the alternative lwp-based thread library on
Solaris 8 by adding the link-time option
-R /usr/lib/lwp (for 32-bit applications)
-R /usr/lib/lwp/64 (for 64-bit applications)The running application use both, the thread and the pthread library can that be a problem? Is it right, that the lwp path include only the normal thread library?
Is there a particular reason why you are using the
obsolete Solaris 8 and the old Sun Studio 10?Because we have customer which do not upgrade? Can we develop on Solaris 10 with SunStudio 11and deploy on 5.8 without risk?

Poor performance after altering tables to InnoDB

I have an application using CF MX, IIS, and MySQL 5.0.37
running on Microsoft Windows Server 2003.
When I originally built the application, access from login to
start page and page to page was very good. But, I started getting
errors because tables were sometimes getting records added or
deleted and sometimes not. I thought the "cftransaction" statements
were protecting my transactions. Then I found out about MyISAM (the
default) vs InnoDB.
So, using MySQLAdmin, I altered the tables to InnoDB. Now,
the transactions work correctly on commits and rollbacks, but the
performance of the application stinks. It now takes 20 seconds to
log in.
The first page involves a fairly involved select statement,
but it hasn't changed at all. It just runs very slowly. Updates
also run slowly.
Is there something else I was supposed to do in addition to
the "alter table" in this environment? The data tables used to be
in /data/saf_data. Now the ibdata file and log files are in /data
and only the ".frm" files are still in saf_data.
I realize I'm asking this question in a CF forum. But, people
here are usually very knowledgable and helpful and I'm desperate.
This is a CF application. Is there anything I need to do for a CF
app to work well with MySQL InnoDB tables? Any configuration or
location stuff to know about?
Help, and Thanks!

Poor Performance after start up and Frequent Crashes

I have a brand new imac i order a little over 6 months ago, i immediately migrated my old imac's files to the new mac and everything worked great but then slowly began to degrade in performance and now i have nothing but problems that have gotten worse.
The first problem occurred with a slow performance speed after about a month of amazing performance.
Then I noticed the new magic mouse i had ordered with the computer would lose connection with the computer causing it to crash, also the new mouse would not hold a charge for long. My last magic mouse did not have this issue.
My computer would fall asleep and then i could be unable to wake it by using my mouse, even plugging in an apple pro wired mouse would not work, i had to turn the power on and off to restart
My bluetooth was acting funny trying to connect to devices i hadn't authorized
Then came a kernel crash.
Then came apple 3 tired support who after weeks of diagnosis over the phone were stumped.
I tried the following to fix the problems myself:
reset the Pram
Repaired Disk Permissions
Checked the hardware
reinstalled the OS
Checked for and installed all software updates
Reset the SMC
Ran 3rd party software "mackeeper" to optimize my files and check for viruses
Clean up unneeded files so plenty of memory
And finally downloaded a 3rd part program called "idrefrag" to defrag my system files.
nothing worked
I was unable to take additional time to deal with the issue, i work and attend school online and was extremely busy during the summer so i had to just deal with the issues because being without my computer was not an option i had.
After my busy summer ended, the problems had only gotten worse
Now, not only does the mac fall asleep and not wake up and not respond to the magic mouse to wake up or reconnect when the mouse and mac lose signal, but now when i plug in a usb flash drive to my external flash drive port, it's like playing russian roulette, half the time it's fine, the other half the computer freeze upon insertion of the drive. I shouldn't have so much anxiety plugging in a 8gb flash drive.
but now on to the worst part, before the summer when i had to restart after crashes it was normal, but now when i restart, the computer acts like it has to remember how to even be a computer again. Upon restarting after the classic Mac tone:
My mac desktop begins to reload, although the icons on the top right appear then disappear and then appear to load back up very slowly.
Moving files to another folder or tp the trash is painstakingly slow, i get a message saying "preparing to move file" that goes on for 10 minutes.
Simple tasks like trying to copy and paste or access my "places" on the side bar like "movies, "Pictures" etc cause a pinwheel and then each "place" has to load all the files as if it's searching the computer for them all before i have access to them, this can take 5-10 minutes
When i click on an application from the dock to load, it just bounces for a while and then finally starts up but takes 5 minutes or more to be able to access without a pinwheel
Overall the computer basically forgets how to be a computer and has to relearn how to do the simplest tasks, the next 24 hours is plagued by pinwheels and slow performance and then it acts fine again, but i can never shut it down or it start all over again, so i just let it fall asleep when not in use and cross my fingers that when i come back it will respond to the mouse and wake up, half the time it does, the other half, i have to restart by holding the power button down and then pressing it to start up again.
I had to just adapt, so i have a good system down now and so when I restart i run the system disk utility and repair the HD 1 & 2 's permission which always seems to have a lot of issues and that kinda helps speed along the 24 hour relearning process. But i shouldn't have to do all this stuff, i spent 3,000 on this computer, i bought all the upgrades and after a couple of months of amazing performance i was left with a time bomb and 3 tier apple support who have no idea where to go and now wont even call me back despite my paying for 4 years of apple care, I am at a total loss of what to do, i can't afford to send the machine off for diagnosis and repair and frankly think Apple should send me a new machine since not only does the mac itself present problems, but so does the new magic mouse, and the rechargeable batteries and charger i purchased from them as well.
My Mac info:
Mac OS X Version 10.6.8
Model Name:          iMacModel Identifier:          iMac12,1
Processor Name:          Intel Core i7
Processor Speed:          2.8 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          8 MB
Memory:          16 GB
Serial -ATA
any suggestions?

Thats a shame, you should be enjoying your mac!, what was the final outcome of the Apple support guys?. I think if it were me and i had tried tried everything that you have including the support tech. i would be pressing for a replacement mac.

SGD + Poor Performance After 3 Hour Connection

Hello,
I have a user who connects from home via a DSL connection to the internet then to a Windows XP VM (VMWARE) through SGD. The performance is good for the first 3 hours or so and then begins to slow down. The user is mainly working in MS Word 2000 and what starts to happen is the screen refreash becomes so slow that she is able to type several sentances with nothing showing on the screen. Then after a few minutes everything appears all at once.
The issue happens everytime the user connects for a long period of time. At first she has no delay issues but 3 hours later the screen refreash is so slow it is not usable. To fix the issue the user reboots the Windows XP VM and closes the SGD connection. She then reconnects and it is good for another 3 hours.
I have logged into the VM here locally when she reports that it is slow and the VM is running fine at normal performance so the issue is not with the VM. We are using RDP to make the connection to the Windows XP VM.
Any ideas why this session is slowing down after about 3 hours of use. She might be my only user who is on SGD for that long (3+ hours) so I am not sure if it would happen with other sessions (users).
Thanks
Bryan Gawronski

Hello,
What you need to know is if the issue is between your SGD server and the VM or between the SGD server and your client?
Might i suggest that you get her to immediately report the issue when it happens next to you and you have a look at the load on the network, cpu and ram on the SGD server and if that doesn't show up anything unusual then login to SGD with her account and resume her session to the VM and see if it is also slow for you.
You could also try other things like giving her another VM to try both when the first one slows down and also instead of the first one to see if it slows down at all.
If you can replicate the error in your own office then it will help you to better troubleshoot the issue.
Hope this can be of some help to you.

Oracle database performance after server reboot

hi masters,
this is not some kind of question, but a discussion. some statements come from our client that after weekly reboot of system, the oracle database performance is low for some time and increase after some time(say 2 days).
i think it is but obvious, because at reboot oracle flushes all cache, and temporary space, so it need to re parse the sql statements and perform some disc I/O's so it might need some time and hence performance will degrade.
but at the same time some people claim that after reboot their database performance is better than their normal performance for some days. it seems controversial that's why i am posting it here.
what might be the reason behind this?? prior can have a valid reason of hard parsing, but what with second case??
any clarification is highly appreciated...
thank you

Vikrant,
You should wait for some time buddy, its weekend ;-) .

I would start from saying that checking the performance when the system just started, is a wrong approach. There would be lots of IOs , parsing, calculations(related to memory allocations) happening so there would be a delay/bad performance at that time. Very simple example can be parsing, another can be memory allocation. Oracle doesn't allocate the entire memory in the instance startup that is allocated to the memory areas but allocates just the bare minimum that is needed to start the instance and than after the startup, it keeps on allocating the memory. So surely enough, with the startup and after a while of it, there would be a different performance than that after the instance hsa already been started and the workload informations have started coming up.
Its correct that Oracle would deallocate all the caches with the reboot as the instance is on the memory(physical) and with the reboot , that would be flushed including the SGA which is allocated over it. Temporary tablespace is now not freed with the reboot. I guess its a rather illogical thing to do but that's what is there now. Oracle keeps the segment allocated even after the reboot is issued, hence the reason for larger temporary tablespaces.

>
This should not come as a surprise once we understand what might be happening with this process. Assume a situation where you have undersized caches. For example, shared pool . which is very heavily used for database , if this is going to be undersized and you are not using automatic memory management, you won't be enjoying the dynamic management of this parameter. Now, if you do lots of parsing , thanks to your wrongly written queries, you would eventually end up filling up shared pool to its max thus leaving no space for incoming new hard parsed cursors. Here , if you can't manage to add more memory to add to it, the only solution left would be to flush the shared pool( as good as rebooting the db because this would do the same) and than make space for the new cursors. The performance is going to be better becausethe cursors would not be getting flushed out immediately and will be kept in the shared pool as long as its not filled up again.Once you have reached to limit of it, again there would be performance benefit. So there are always odds added to the statements like this that I rebuilt my index , I got better, I rebooted my server, my querie are much faster now. Most of the time when these kind of statements are given, they are based on what we have seen, without understading what actually might have happened. So I would siggest to hear the statement but not take them as a rule of thumb to follow.
Hope this all makes some sense for you and would help somewhat.

InDesign (and Acrobat) poor performance after virus - ideas?

Hi everyone,
we have a problem with our system (spec listed below); I've also posted in the Acrobat forum since it is affected as well.
System
Dell Precision T7400
CPU(s): dual quad core Xeons
RAM: originally 2GB, upgraded to 4GB 1 day ago
OS: XP 32-bit
Adobe Software: Originally CS3 Suite, now CS5 Suite
Acrobat 9 Pro
Problem
Acrobat: 1. stutters slowly when scrolling, almost crashes
2. Takes 4X longer than before to "Reduce file size" for PDFs
InDesign: stutters slowly when working with text and tables, almost crashes
Cause
Virus infultrated system about 1 month ago.
Attempts
1. Re-imaged disc and installed software based mirroring software with 2 extra backup drives: system still lags
2. Re-formatted, reinstalled: system still lags
3. Turned off mirroring: helped a little
4. Ran various memory, motherboard tests: nothing found
5. varified all BIOS and firmware up to date
6. Uninstalled mirroring software, installed hardware based mirroring software, reformatted, reinstalled: system still lags
7. Tried working with files directly from C:/ with no mirroring: system still lags
8. Installed fresh 4GB memory: system still lags
9. Have tried all methods of helping InDesigns performance but no luck.
Thoughts
Comparing this system to my old laptop (Centrino Dual Core), the laptop runs about 4X faster since the virus. Before the virus, this system was a dream to work with, super fast speed, never lagged.
I keep thinking that the virus must have damaged somthing on the motherboard, but error messages or motherboard beep codes.
Any other suggestions (short of shotting this system) would be greatly appreciated.

You didn't actually re-flash your BIOS, did you? Yes
If it was fast before the infection, and slow after the reformat, then this is pretty much the only place that anything could be different. I'd be more inclined to test hardware than continue chasing software, in your shoes.
Ran various RAM tests, and the BIOS shows nothing out of the ordinary.
But it's certainly nothing to do with the software, unless the new install was botched for reasons having nothing to do with the virus, or that the virus is actually hiding in one of the spots on the motherboard that can be written to, like the BIOS.
Clear one thing up for us - you say
Adobe Software: Originally CS3 Suite, now CS5 Suite
Does that mean "it ran like a dream with CS3, but now that I have CS5 it's running slow?" Because, if so, you're chasing a red herring - CS5 consumes a lot more in terms of computing resources than does CS3. You should be looking at how to tame CS5's resource consumption, and there are plenty of threads about that.
After the reformat, CS3 Indesign was a dog as well as Acrobat 9 Pro. Upgraded to new CS5 Suite (all but Acrobat 9 Pro). CS3 & 5 Indesign still a dog as well as Acrobat 9 Pro
Lastly, I haven't seen malware hiding in flash ROM on the motherboard more than once in the last decade. It wouldn't generate any error messages or beep codes, either.
Same here, have not witnessed malware/viri infultrating the BIOS since back in 99'. Never the less, it's the only idea I can come up with. I have yet to locate any software for testing the NVIDIA NVS 290 video card. This is the strangest issue I have seen ever.

SQL 2005 x64 poor performance after migration from SQL 2005 x86

Recently We've migrated SQL 2005 x86 SP1 Enterprise running on Windows 2003 Enterprise to new hardware where is running Windows 2008 SP2 and SQL 2005 x64 SP4 with CU3.
In the work day, there are sometime SQL excpetions like this below. On other hand i can also tell that we already found some queries which has some inner joins and where clauses on nvarchar fileds, because of the nature of application. Such a query
is running for about 11 seconds on old SQL server, and about 6 minutes on new SQL server. My main question if is this possible just with a change to new architecture of SQL and more last patches and updates for SQL 2005. Is there any way how to get
this queries running faster, without rewritng them with new ones? Is this also possible this could be also cause for SQL exceptions, which we are facing on SQL server?
About new hardware, for now we can't find it something wrong. There is basic configuration:

>Is there any way how to get this queries running faster, without rewriting them with new ones?
You need to perform basic performance tuning steps in the new environment.
Software optimization:

Memory optimization:

REBUILD INDEXES, eliminate missing indexes & UPDATE STATISTICS.
If there is still a problem, look in Activity Monitor for expensive queries. Optimize them. As a general rule, you don't want to have expensive queries in RDBMS.

Poor performance after moving from hp to linux, oracle 11.2.0.1 to 11.2.0.3, filesystems to ASM

We moved a database from HP/UX to linux, upgraded oracle from 11.2.0.1 to 11.2.0.3, and from filesystems to ASM. The new server has 32 cores and 500gb of memory. the old server has less than half of that. Queries take twice as long to run on the new server as on the old server. We've tested to eliminate I/O as the issue by creating a local filesystem and creating the database there. The performance was still double over the old database. We also moved the database to a 3rd server, using ASM and 11.2.0.3 of oracle for testing to prove to the systems administrator that it wasn't a database problem. The performance on the 3rd server is incredibly fast. This points to something on the new server. Does anyone have any ideas of what to look at next, keeping in mind that we've tested the heck out of I/O.
Thanks for any assistance.

Well, a few details about your configuration could help:
What does /proc/meminfo on the server show?
How is the storage connected?
What does: "# /sbin/ifconfig -a" show?
Are you using ASMLIB or straight ASM?
Are you using multipath connections to storage? If so, make sure that "/etc/multipath.conf" actually identifies the composite device and not one of the physical paths.
Are there any entries in "/var/log/messages" while running the ASM testing?
I'm sure these questions will stimulate others.

Poor Performance after Compute Statistics

Hi Guys,
Has anyone had this problem before:
Database and application is running at about 700ms response time with very little io. After performing dbms_stats.gather_database_statistics, the performance drops to about 4 sec response time, with lots of FTS. After bouncing the DB, the performance goes back up to 700ms with very little io.
Version is 8.1.7 with db spread on two drive spindles with approx 1GB db buffer cache.
Any ideas? Urgent response requested.

Hi Donald,
Do you specify a large sort_area_size or alter any session parameters for dbms_stats to complete quicker?
Or did you run the query when the dbms_stats was running?
These could cause issues once the process completes.
A DB bounce does not alter the statistics for the tables and the performance before and after the bounce, unless there was something else that was running and impacting the performance of the query.
Hth.

Poor performance after format and OS install.

GT70 0ne
3610qm
680m
24g Kingston ram
Win7 64
Yesterday I formatted my drive and installed win7 64, after installing all the (old) drivers on the MSI website (link below), in the correct order, then waiting a good 8 hours for all the windows updates to install, I booted up WoW and found horrible FPS. I ran 3dmarks 11 and scored a dismal 2600 with my graphic and combined scores around 2500 and the physics at the normal 8500.
Searched online for some solutions, put the 680m as the default for WoW and 3dmarks but with no difference. I went ahead and got the latest drivers for the 680m off the Nvidia website and saw no improvement.
I did not install any utilities from the MSI website, are any of them needed for the proper function of the laptop or are they all fluff?
I did not install any firmware either, Is it needed?
Should I download the latest drivers for all the components or stick with MSI's?
The laptop itself is extremely quick when not needing graphical power.
Thank you.

The following factors will affect the performance score:
- Using AC or DC.
- Power plans (Windows). High-performance or Balanced mode.
- Numbers of background processes.
- Wi-Fi/BT on or off.
- Improvements from newer BIOS, EC, or Video BIOS versions.
- Screen brightness (slightly affected).
Your score is indeed a little lower. Check the points above to improve it.

Extremely poor performance after update to 1.6

Hi,
I've recently updated to 1.6 from 1.5 and now any webpage that contains java applets takes anywhere from 20 seconds upto 1 minute to open and start. Is there a problem or should i just uninstall java completely?

Can you give an example of the applet that you are using?
Also, what OS are you using on the computer having this problem?

Apple maps has received a poor performance rating just after introduction of the iPhone 5. I am running google maps app on the phone. Siri cannot seem to get me to a specific address. Where does the problem lie? Thanks.

Apple maps has received a poor performance rating just after introduction of the iPhone 5. I am running Google Maps app on the phone. SIRI cannot seem to get me to a specific address. Where does the problem lie? Also can anyone tell me the hierarchy of use between the Apple Maps, SIRI, and Google maps when the app is on the phone? How do you choose one over the other as the default map usage? Or better still how do you suppress SIRI from using the Apple maps app when requesting a "go to"?
I have placed an address location into the CONTACTS list and when I ask SIRI to "take me there" it found a TOTALLY different location in the metro area with the same street name. I have included the address, the quadrant, (NE) and the ZIP code into the CONTACTS list. As it turns out, no amount of canceling the trip or relocating the address in the CONTACTS list line would prevent SIRI from taking me to this bogus location. FINALLY I typed in Northeast for NE in the CONTACTS list (NE being the accepted method of defining the USPS location quadrant) , canceled the current map route and it finally found the correct address. This problem would normally not demand such a response from me to have it fixed but the address is one of a hospital in the center of town and this hospital HAS a branch location in a similar part of town (NOT the original address SIRI was trying to take me to). This screw up could be dangerous if not catastrophic to someone who was looking for a hospital location fast and did not know of these two similar locations. After all the whole POINT of directions is not just whimsical pasttime or convenience. In a pinch people need to rely on this function. OR, are my expectations set too high?
How does the iPhone select between one app or the other (Apple Maps or Gppgle Maps) as it relates to SIRI finding and showing a map route?
Why does SIRI return an address that is NOT the correct address nor is the returned location in the requested ZIP code?
Is there a known bug in the CONTACTS list that demands the USPS quadrant ID be spelled out, as opposed to abreviated, to permit SIRI to do its routing?
Thanks for any clarification on these matters.

siri will only use apple maps, this cannot be changed. you could try google voice in the google app.

Databases are not coming up after server reboot(sun solaris).

Hi
OS - Sun OS 5.10 local zone. RDBMS version - 11.2.0.3
Databases are not coming up after server reboot.
We have verified the below points.
Cat/etc/init.d/oracle
$ORACLE_HOME/bin/oradism file permissions are 4550.
lock_sga is parameter set to false.
cat /var/opt/oracle/oratab entries are set to Y
Still Databases are not coming up after server reboot.
Please advise.

Hi,
Can you post further information from alert log. Doesn't coming up, means you needs to share the information some thing about your environmente settings about kernel parameter and init$ORACLE_SID parameters details.
That would be easy for others to look into it further to analyze things.

Project Server 2013 Poor Performance

Hi Guys
On a new build of Project Server, we are experiencing poor performance across the board, Site Collection, Central Admin, everything is slow.
We have allocated 12GB and Quad core (lower end of the recommend scale). However as there are no users, I would expect it to be fine at the moment (Search is not setup or anything, just a simple service app with a pwa site provisioned).
What things can we check? From looking on the internet, Distributed Cache crops up a lot. Can this bring performance right down?
For the record, we have March 2013 PU and Oct 2013 CU applied.

Hello,
There could be a number of causes, it is very difficult to diagnose without understanding the farm infrastructure. Can you give details of:
Number of servers in the farm + Specs
If virtual, is the host server over committed? Have you set up reservations for memory and CPU?
What is the storage?
What is the network speed between servers / storage etc?
Do you have any Anti-Virus software installed on the servers? If so, have you tested with it disabled on all servers in the farm?
