Slow System Performance on SunOS 5.10

Dear all,
Our system experienced very slow response time a few days ago. After checking the wp trace file, we found the oracle is out of memory and there were some malloc failed(not enough space). Our system is ECC6 SR3 SP 16 and Oracle 10g dbase with RAM 4GB and swap 16 GB on container of SunOS 5.10.
My assumption when the process running out of memory, it should retrieve from virtual memory. At command vmstat -s the output of swap in/out and pages swapped in/out is zero. Guess problem with vm of container. Anyone can help? Thanks.

Slow system performance...

Hey guys, i recently installed Arch Linux via my 0.7.2 CD. I then did a full system upgrade, up to the 2.6.19 kernel, boots fine, followed the new kernel instructions.. however it just seems like my overall system performance is SLOOWW. Keep in mind, i have installed Arch on this computer when 0.7.2 first came out, and it ran perfectly fine, everything ran fast. However now since i did a fresh install, upgraded to the latest, things seem slow.
i have installed xorg as well as gnome, including the nvidia drivers. When ever i type startx, it takes more then a few seconds for anything to happen after the command has been entered, before it would be VERY snappy. Gnome seems to take longer to load as well. When i launch xterm from within gnome, it takes a while for the xterm window to show, this includes any other windows. When i move windows around overtop of firefox, it seems alot of ghosting is happening, alot of trailling over the desktop when the window is being dragged overtop another window. I checked to see if Nvidia drivers are being loaded which they are. a glxtest reports back a 1500fps + as well as showing nvidia corporation in the glxinfo....
This is a fresh BASE install, upgraded to the current, then Xorg and gnome installed. Top shows no high cpu spikes and i cant figure out why suddenly, application loading seems to be slow...
P.S also, with all of this, accessing webpages seem very slow as well....this includes Pinging an IP address...

well, i added that in, startx as well as gnome + application seem to load as they should now, if that was the reason thanks for telling me about that.
However my internet is still very very slow. Booting into Windows XP i can confirm its not my internet connection, no lag in XP, however in Arch, seems very slow. If its any help, im using the sundance driver
actually, now that applications seem to be loading as they should, my internet connection probebly can be asked in the network section?

Slow System Performance after binding Machine to OD

Hello,
I've recently installed Leopard Server using standard configuration. I bound two machines to test and I noticed immediately that I took a performance hit speed wise just doing regular stuff like opening applications and browsing internet takes longer than usual for some reason now they use to pop instantly prior to binding to Server. So I broke the connection to see if the server was causing the lag but both machines for some reason now continue to lag. Does the server alter the client in some way that affects its performance? and why does it still affect the machine after the connection is broke? Any input is appreciated.

Just binding a client to an OD server shouldn't make any noticeable difference in speed, assuming that the network is set up correctly. Network homes certainly will slow you down compared to local homes.

Slow System Performance! [With Benchmark Results]

Hello,
I've a MacBook Pro (mid 2011) 15" model with the following configuration:
Core i7 2.3 GHz
8GB RAM
256GB SSD
OS X Lion 10.7.2
(No 3rd party software installed expect GeekBench tool)
I ran the GeekBench tool and result is available here: http://browse.geekbench.ca/geekbench2/view/498196
I primarily suspect SSD, since it's performance is not up to the mark. I would appreciate if anyone can provide me more info based on the SSD performance for the above result (link.)
Thank you!

I just ran X-Bench tool and compared it to Anandtech benchmark results (with the same SSD and tool types) and the screenshots are provided below:

Process Order tables and Production System Performance

Hi All,
What are the different tables of Process order? Also how do i know which table affects the system performance of Production system and to what extent if Change Logging is made active ?
The issue is in our clients place we would like to set the Change Logging ( Records changes made for any transaction ) for Process orders and we would like to know to which tables change logging should be made active so that Production system performance is not affected.
Please help me regarding this.
Thanks in Advance,
Neetha Avani.

All the changes done in any transaction are saved in CDPOS table.
when there is any report developed based on this table then the performance will be very slow.
Tables used for process orders are
AFKO            Order header data PP orders
AFPO            Order item
AFRU            Order Confirmations
AFRUHR        Order Confirmations for HR
AFRV             Confirmation pool
AFVC             Operation within an order
Hope the above helps.

T520 - 42435gg / Sound stutter and slow Graphic performance with Intel Rapid Storage AHCI Driver

Hi everybody,
I have serious Problems with my 42435gg
Any time I install the Intel Storage AHCI Driver (I've tried plenty of different versions) which is suggested by System Update I experience a horrible Sound stutter and slow Graphic performance in Windows 7 64-Bit.
The funny thing in this case: If the external e-sata port is connected the problems do not occur. If the port is unused again, the stutter begins immediately.
The only thing I can do is using the Windows internal Storage Driver with which I am not able to use my DVD recorder for example.
The device was sent to lenovo for hardware testing with no result. It was sent back without any repairing.
Anybody experience on this?
Kind regards,
Daniel

Did you try the 11.5 RST beta? Load up DPClat and see if DPC conditions are favorable.
What are you using to check graphics performance?

Degraded system performance - possibly caused by external LaCie HD

I'm stumped over what to do to solve a serious performance problem with my iMac. Here's the setup:
Prior to today, I've been running:
An iMac Intel Core 2 Duo 17" (late 2006). The guts of it all OEM: 1 GB (2x512) RAM, 250 GB HD, SuperDrive.
A 500 GB LaCie USB 2.0 External HD.
Two external optical drives; one that can read/burn CDs and one that can read//burn DVDs/CDs. Both of these are connected via FireWire
Operating system: Mac OS 10.4.x
Network: Wireless Airport on iMac to DLink wireless router to Sympatico DSL. Using OpenDNS
Over the last few weeks, system performance (and by this, I mean basic tasks like copying a file or selecting a menu option or switching between apps) has degraded to the point where it could take several seconds simply switching from one app to another. No new software or devices were added over this time.
Running Apple's Hard Disk Utility, I discovered some "Minor" problems on the internal hard drive. I booted up in safe mode, which automatically forces a disk repair, and, upon running disk utility again, the disk appears fine.
Performance problems persisted.
I ran disk utility on the external drive. No problems.
Earlier this week, I decided to upgrade the OS.
The upgrade took 5+ hours to install. (I'd heard it can take a while but 5 hours seems silly).
Performance problems persisted.
Last night, I loaded everything I needed on the internal drive and backed up to the external drive. THen I proceeded to do a clean install of the OS 10.5.6. I ran Software Update to get the latest Java machine and other updates.
Still got problems. (Copying 2 GB of files I'd backed up on my external drive back to the internal drive took more than 2 hours! via USB 2.0)
Ran Hard Disk Utility again. Everything's fine. Still have performance problems.
Shut power down on all external drives and re-booted.
Ah-ha! Now we're gettin' somewhere. Performance seems normal. System is responding to basic commands in the what seems like a normal way.
But I need those external drives. First bright idea: Perhaps it's the cheap Dyntech 5-port USB hub that's gumming things up. To test, I disconnected the hub and connected the LaCie external drive directly to the iMac.
Back to the same old problem.
Ok -- so it seems pretty clear that the iMac and the LaCie drive, which once got along famously, are now like an old married couple -- grumpy and slow to respond to each other's requests. Again -- neither the LaCie drive nor the iMac internal drive report any problems via Hard Disk Utility. Files are being successfully copied back and forth albeit at a mind-numbingly slow speed. But for all intents and purposes, so long as the iMac is attached to the LaCie drive, it has all the zip and functional usefulness of my old Centris 610.
Any and all suggestions gratefully welcomed.

True unless you frequently attach and detach the drive so that indexing never is completed. To see if this may be the case with the drive attached, open Spotlight preferences, click on the Privacy tab, then drag the drive's icon into the list.
You can also try a few other things, but start by downloading and installing AppleJack - VersionTracker or MacUpdate. Read instructions and run the program to do some cleanup. For other maintenance tips see:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. CloneTool Hatchery (Shareware)
12. Clone X (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.

Windows 8.1 File System Performance Down Compared to Windows 7

I have a good workstation and a fast SSD array as my boot volume.
Ever since installing Windows 8.1 I have found the file system performance to be somewhat slower than that of Windows 7.
There's nothing wrong with my setup - in fact it runs as stably as it did under Windows 7 on the same hardware with a similar configuration.
The NTFS file system simply isn't quite as responsive on Windows 8.1.
For example, under Windows 7 I could open Windows Explorer, navigate to the root folder of C:, select all the files and folders, then choose
Properties. The system would count up all the files in all the folders at a rate of about
30,000 files per second
the first time, then about 50,000 files per second the next time, when all the file system data was already cached in RAM.
Windows 8.1 will enumerate roughly
10,000 files per second the first time, and around
18,000 files per second the second time -
a roughly 1 to 3 slowdown.  The reduced speed once the data is cached in RAM implies that something in the operating system is the bottleneck.
Not every operation is slower. I've benchmarked raw disk I/O, and Windows 8.1 can sustain almost the same data rate, though the top speed is a little lower. For example, Windows 7 vs. 8 comparisons using the ATTO speed benchmark:
Windows 7:
Windows 8:

Configure The Windows 8 "To Work" Options

No worries, and thanks for your response.
The problem can be characterized most quickly by the slowdown in enumerating files in folders. Unfortunately, besides some benchmarks that show only an incremental degradation in file read/write performance, I don't have any good before/after
measurements of other actual file operations.
Since posting the above I have verified:
My system has 8dot3 support disbled (same as my Windows 7 setup did).
Core Parking is disabled; CPU benchmarks are roughly equivalent to what they were.
File system caching is configured the same.

What does kind "PowerPC" mean for system performance?

Hello,
I installed Kompozer to edit some HTML. I went to Activity Monitor and saw the Kind as "PowerPC". What does that mean for system performance? Will the system run slower overall or will just the program? Thanks.

PPC means it will run via Rosetta. You may notice no difference, or even a slight increase in performance due to higher processor and RAM specs on your Mac as opposed to a PPC model.

CS5 on mac 10.6.4 slows system to a crawl, render times really long

We recently upgraded our towers to 10.6.4 and all productivity has slowed to a snails pace using After Effects. On 10.5 the speed was almost TOO fast on our renders...it was awesome. Now I'm looking to get that speed back.
I have a few very simple comps. 1920 x 1080, 23.98fps, 5 layers (4 QT renders from final cut XDCAM and Animation codec, 1 adjustment layer with levels and hue/saturation for color correction). Approx 40 seconds long each.
I've followed the Adobe advice of turning the multiprocessing on and using the following settings from here http://forums.adobe.com/thread/543440
leave 4gb for other apps, set minimum 3gb per processor = 33min render
setting it back to what WAS screaming fast on 10.5:
leave 3gb for other apps, set minimum 0.75gb per processor = 19min render
turning multiprocessing off = 5min render
same project on 10.5 system with multiprocessing turned ON with the above mentioned settings = 2min render
what is going on here? is there a compatibility problem with CS5/10.6 and Animation codec files? that seems to be the bulk of the slowdown, but still over twice as slow?
additionally, when AE is rendering the rest of the system becomes unusable...every action, even dragging a finder window around, results in beachballs and a 30 - 40 second lag in response. this happens with or without multiprocessing.
I just want to get back to work...any ideas on how i can configure this beast to get back to my former speeds?
8 core mac Pro
OS 10.6.4
12gb RAM
many thanks in advance. i'm willing to send beer for a winning fix.

Good to know, thanks for the update. 10.6.x does manage memory differently, but our testing for performance has shown a slight improvement in the newer OS. So I am guessing that the OS update is not the issue. I just ran another test on a Mac with your configuration and saw a 4% improvement on 10.6.4 over 10.5.8.
It's uncertain what state the system memory was in when you started your tests. That's why I asked for a restart of the computer. The times reported seemed like there was a possibility that the OS was swapping. XDCAM footage places a high demand on system resources. But it's hard to say without being there.
What I was seeing with the initial post was that the two extremes of allocation per background cpu were tried, but not the middle ground. To better see this, launch the Activity Monitor utility or look at the last line of the MP preference. With the 4GB reserved and the 3GB/ bkgnd cpu setting you weren't getting any extra processes spawned for multiprocessing. You can see this in the preferences multiprocessing section as "Actual CPUs that will be used = 0". Then, by setting the pref to .75GB/bkgnd the app launched 8 bkgnd processes, but for the task at hand, I am guessing that they were starved for memory and sometimes failed to render. This was faster than the first test, but still slow. By setting the pref to 1.5GB/bkgnd cpu you were now getting 4 new processes spawned for multiprocessing. The background processes had enough memory to succeed so that made it render faster still.
Now, try setting it to 1GB/bkgnd cpu. That will launch 6 processes which should render faster as long as that is enough memory for the task. If the Memory pref for Reserve RAM for other apps is set back to 3GB, it will allow the spawning of 7 bkgnd processes. If that is a successful balance for this project then it will be the fastest render time. But, our testing shows it will be at the risk of starving the OS for memory, thus the more conservative 4GB recommendation for a 12GB system.
It's a fine line and why we are recommending that one give up a little speed by reserving more memory for other apps. True, there will be less processes spawned for multiprocessing, but there will also be less chance for the OS to start swapping to disk which greatly slows down performance for all tasks. If that compromise is not acceptible, then the alternative is to buy more ram so that all 8 processes can adequately receive enough memory for the job, and yet still maintain adequate reserves for the OS and other apps.

Ironport System Performance

Hello,
Just wondering if anyone is noticing that after each upgrade they do of AsyncOS, the performance of the system goes down and down.
We have been running our C60s for 1 1/2 years, starting with the 3.8 build of AsyncOS.
After this last build (4.5.5) we are averaging over 70 percent on our CPU's.
We process about 30,000 inbound connections per hour, which is well below the 140,000 advertised that the box can handle.
We are not running anything strange... no content scans, no dictionary matches. Just your basic file attachment blocking, AV and Antispam.
Thanks!

No -
I only changed the reportinglevel. Ironport tells me the following facts about this issue (please read from downwards to up)
Hi Jens-Uwe,
Some more data for this case. I'm not sure if PostX will be on box for a
C100 or not. The action to encrypt will be as fare as I know, but the
whole PostX web front-end functions will not be on box. The main problem
C10/C100 are facing is the small amount of RAM. It's only 1GB and the
raid is a soft raid, which is way swapping becomes really expensive in
terms of CPU usage.
Reporting in 5.0 and 5.1 has become more resource hungry and needs a lot
of RAM if used in full mode. Moreover the GUI has a very low priority
(for the CPU scheduler), which is painful for administration.
We don't sell extra RAM for any IronPorts.

Mark Strasheim

Hello,
If you say "30% disk swap space being used, which is high" you means that is not enough ram at the C10 ? Should and could I place some additionally RAM in the C10 ?
Yes at the moment I do a dual scanning with brightmail und ironport anti spam. But this is not the cause, for the heavy load, because I was able to enable this with the update to 5.1 2-3 weeks ago. The performance leak was already there, before I enabled the dual scanning and the situation was not gone awry after this action. But please disabled it, If you would test it.
Remember, you are you looking at our time 11.30pm. At this time there is nobody in the office. Therefore there is no mailflow (or much fewer).
Also we are already minimized the logging (limited monitoring functions)
I mean, to see really what is happened, you have to log in at 10.00am our time and we have to maximize the logging.
Best regards
Neumann
I think that is clear, waht was happend after the update :(

EXTREMELY SLOW XQUERY PERFORMANCE AND SLOW DOCUMENT INSERTS

EXTREMELY SLOW XQUERY PERFORMANCE AND SLOW DOCUMENT INSERTS.
Resolution History
12-JUN-07 15:01:17 GMT
### Complete Problem Description ###
A test file is being used to do inserts into a schemaless XML DB. The file is inserted and then links are made to 4
different collection folders under /public. The inserts are pretty slow (about
15 per second and the file is small)but the xquery doesn't even complete when
there are 500 documents to query against.
The same xquery has been tested on a competitors system and it has lightening fast performance there. I know it
should likewise be fast on Oracle, but I haven't been able to figure out what
is going on except that I suspect somehow a cartesian product is the result of
the query on Oracle.

Hi Arnold,
you wrote -
Please use Sun JDK 1.5 java to perform the test case.Right now I have -
$ which java
/usr/bin/java
$ java -version
java version "1.4.2"
gcj (GCC) 3.4.6 20060404 (Red Hat 3.4.6-3)
sorry as I told you before I am not very knowledgeable in Java. Can you tell me what setting
s I need to change to make use of Sun JDK 1.5. Please note I am testing on Linux
. Do I need to test this on a SUN box? Can it not be modify to run on Linux?
Thanks,

Poor System performance after EHP4 upgrade

Hello Experts,
We have just finished our Upgrade to EHP4 for ECC6 system. After the upgrade we are noticing awfully slow system response time.
My SGEN is currently executing and it's showing another 45 hours before it is finished. Are there specific post Upgrade activities that I am missing? Once I try to perform some action it takes ages to compile the program. I undesratand that since SGEN is not run yet so it will need some time to compile and generate load for the application but still the response is takinng agaes before I see the actual Application/Program active in GUI.
Please suggest what I can do to boost up my system performance.
Thanks,
M

Hi Sunny,
Another Update
I looked at SAP Note 146289 - Parameter Recommendations for 64-Bit SAP Kernel
Following is the recommnedation:
Implement the SAP profile parameters as follows:
em/initial_size_MB 1024 up to 1TB (note 835474)
em/blocksize_KB 2048, 4096 or 8192 (note 835474)
ztta/roll_first 1
ztta/roll_area 6500000
The deafult value of the following parameters is 2000000000 (2GB).
They can be changed depending on the HW (RAM) and the configured
SWAP Space:
ztta/roll_extension 2000000000 (2GB)
abap/heap_area_dia 2000000000 (2GB)
abap/heap_area_nondia 2000000000 (2GB)
abap/heap_area_total 2000000000 (2GB)
But same SAP Note refers for windows:
For Windows 64Bit recommendations see note 88416:
As per this note recommendations are as follows:
Standard values for zero administration memory management
[HS] = size of the physical main memory
[PM] = value of the profile parameter PHYS_MEMSIZE (standard value=[HS])
[BE] = maximum possible number of users (calculated from [PM])

PLease note that ours is a 64Bit kernel for WIndows 2003
x86_64
So is it ok to change the value of abap/heap_area_nondia ?
Thanks,
