IMovie 09 Memory-Performance Problems-Desperate for an answer!

I am in the process of using IM09 to create a slideshow using stills combined with music and a couple of movie clips. It is approx. 24 mins in length.
I have noticed that performance is getting pretty bad, including lag times in positioning transitions, etc., as well as preview playback when tapping the space bar. Sound pops, and certain frames either don't show up, are replaced with the wrong ones, or appear as black.
Appleman1958 mentioned it might be a virtual memory problem, I have restarted several times, with no improvement. So, I am wondering if it might be because the source jpegs are on another drive, or because 2GB of ram aren't enough. I read in these posts that the cache for the project can be trashed from within the package located in the movies folder. I have no idea what to do---I'm going nuts, PLEASE HELP!!!!
Thanks, Carl

Performance Problems with "For all Entries" and a big internal table

We have big Performance Problems with following Statement:
SELECT * FROM zeedmt_zmon INTO TABLE gt_zmon_help
FOR ALL ENTRIES IN gt_zmon_help
    WHERE
    status = 'IAI200' AND
    logdat IN gs_dat AND
    ztrack = gt_zmon_help-ztrack.
In the internal table gt_zmon_help are over 1000000 entries.
Anyone an Idea how to improve the Performance?
Thank you!

You can't expect miracles. With over a million entries in your itab any select is going to take a bit of time. Do you really need all these records in the itab? How many records is the select bringing back? I'm assuming that you have got and are using indexes on your ZEEDMT_ZMON table.
In this situation, I'd first of all try to think of another way of running the query and restricting the amount of data, but if this were not possible I'd just run it in the background and accept that it is going to take a long time.

Performance problems when using Premiere Elements for photo slideshows

Hello,
I had been using Premiere Elements 9 (PE9) to make a simple slideshow for my parents from their vacation trip and I ran into some serious performance problems. I had used it to create similar projects before, but not nearly as big. This one is like 260 photos, so basically it is 260 seperate clips. I have a POWERHOUSE workstation (see below) so it isn't my PC. Even when PE9 crashes, looking at my performance monitor my CPU and RAM aren't even halfway being utilized. I finally switched to Windows Movie Maker of all things and it worked seemlessly, amazing really. I'm wondering if I was just using PE9 for something other than what it was designed for since there weren't really any video clips, just a ton of photos that I made into video clips, if that makes sense. Based upon my experience with this so far, I can't imagine using PE9 anymore for anything really. I might have the need for a more professional video editing program in the near future, although it does seem like PE has a lot of features. How can I make sure it utilizes my workstation to its full potential? Here are my specs:
PC
Intel Core i7-2600K 4.6 GHz Overclocked
ASUS P8P67 Deluxe Motherboard
AMD Firepro V8800 Video Card
Crucial 128 GB SATA 6Gb/s Solid State Drive (Operating System)
Corsair Vengeance 16GB (4x4GB) Memory
Corsair H60 Liquid CPU Cooler
Corsair Professional Series Gold AX850 Power Supply
Graphite Series 600T Mid-Tower Case
Western Digital Caviar Black 1 TB SATA III Hard Drive
Western Digital Caviar Black 2 TB SATA III Hard Drive
Western Digital Green 3 TB SATA III Hard Drive
Logitech Wireless Gaming Mouse G700
I don’t play any games but it’s a great productivity mouse with 13 customizable buttons
Wacom Intuos5 Pen Tablet
Yes, this system is blazingly fast. I have yet to feel it slow down, even with Photoshop, Lightroom, InDesign, Illustrator and numerous other apps running at the same time. HOWEVER, Premiere Elements 9 has crashed NUMERUOS times, every time my system wasn't even close to being fully taxed.

Andy,
There ARE some differences between PrE and PrPro w/ an approved CUDA-capable and MPE hardware acceleration-enabled nVidia video card, but those differences show up ONLY in the quality of the Scaling. The processing overhead is almost exactly the same, when it comes to handling the extra pixels.
As of PrPro CS 5, two things changed:
The max. size of Still Images went up from 4096 x 4096 pixels, to quite a bit larger (cannot recall the numbers now).
The Scaling algorithms have been improved, though ONLY with the correct nVidia cards, with MPE hardware support enabled.
Now, there CAN be another consideration, between the two programs, in that PrPro CS 5 - CS 6, are 64-bit ONLY, so one benefits from the computer and OS to run it. PrE can be either 32-bit, or 64-bit, so one might, or might not, be taking advantage of the 64-bit program and OS. Still, the processing overhead will be almost identical, it's just that the 64-bit OS can spread it around a bit.
I still recommend Scaling the large Still Images in PS, prior to Import, to keep that processing overhead as low as is possible. Scaled Still Images work just fine, and I have one Project with 3000+ Scaled Still Images, that edits just fine in PrPro, even on my older 32-bit workstation. Testing that same machine, and PrPro some years ago, I could ONLY work with up to 5 - 4096 x 4096 Stills, before things ground to a crawl.
Now, Adobe AfterEffects handles large Still Images differently, so I just moved that test Project to AE, and added another 20 large Images, which edited just fine. IIRC, AE can handle Still Images up to 10K x 10K pixels, and that might have gone up, as of CS 5.
Good luck, and hope that helps,
Hunt

3D performance problems after upgrading memory

I recently purchased an additional 2GB of memory to try and extend the life of my aging computer. I installed the memory yesterday and Windows seems to recognize it (reporting now 3.3GB) but when I dropped into WoW (pretty much the only game I have) the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages). Basically WoW was being software 3D rendered!!!
I went through the usual reinstall drivers, reboot, etc... and couldn't find a fix. I powered down, pulled out 2 of the memory sticks, booted up, and dropped into WoW - it ran at the full 60FPS and CPU utilization was very low (i.e. back to GPU Hardware 3D rendering). I powered down again, swapped the 2 sticks for the other 2 sticks, booted up, and dropped into WoW - again it ran 100% fine. So I powered down, put all four sticks in, booted back up, and when I dropped into WoW it was running in the software 3D rendering mode (20FPS at best and High CPU/Kernel usage).
I've tried the /PAE option in boot.ini - no joy. I've tried /MAXMEM = to 3300, 3072, 3000, and even 2048 - no joy in any of those cases. Has anyone seen anything like this before? Or have suggestions to fix (other than going to Win7-64)?
All info in signature is up to date.
Thanks in advance for any help!

PAE or Physical Memory Extension will not do anything as Microsoft has castrated this feature to such an extend that it has nothing to do with memory addressing anymore when in comes to Windows XP:
http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows
Quote
Windows XP Service Pack 2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX. The NX (or XD) bit resides in bit 63 of the page table entry and, without PAE, page table entries only have 32 bits; therefore PAE mode is required if the NX feature is to be exploited. However, desktop versions of Windows (Windows XP, Windows Vista) limit physical address space to 4 GiB for driver compatibility reasons.
The feature is already automatically enabled. But since is original function (Address Extension) does no longer exist when it comes to the desktop versions of Windows XP, it won't really do anything you would ever notice.
About the /MAXMEM Switch: In Windows 32bit operating systems, every process is limited to 2GB of memory. The point of the switch is to allow certain applications (or their run-time process) to occupy a higher amount of system memory than 2GB. However, the culprit here is that only those applications are able to utilize this ability that have been programmed (or compiled) accordingly. A special flag (large memory aware) has to be implemented. Otherwise, these application will be restricted to 2GB even though the /MAXMEM Switch has been set to extend the 2GB limit to 3GB. Most 32bit applications come without the "large memory aware" flag and that is why usually, settings the switch won't change anything.
In any case, it is unlikely that /PAE (even if it would not be castrated) and /MAXMEM would have an impact on your actual issue because I doubt that it has much to do with either memory adressing or the memory limit of an indiviual Windows process.

There are a couple of hardware based explanations to consider here. Let's start with the most obvious one:
1. 975X Memory Controller
The main reason that the system chooses to automatically set the Memory Speed to DDR2-667 even though DDR2-800 modules are installed, is that by design the memory controller of the Intel 975X Chipset does not natively support DDR2-800 modules, but
>>Intel® 975X Express Chipset Datasheet - For the Intel® 82975X Memory Controller Hub (MCH)<< [Page 20]
This means, that from the point of view of the memory controller, operating the memory @DDR2-800 actually means overclocking it (with all potential side effects).
Basically, if your initial problem disappears as soon as you reduce the memory speed to DDR2-667, the design limitation of the memory controller may explain your findings.
2. Different memory modules
If I read your signature correctly, you are actually mixing two different kits/models of RAM (CM2X1024-6400C4DHX and CM2X1024-6400C4). This can work of course, but in practice it not necessarely does under all circumstances.
This list (-> http://ramlist.i4memory.com/ddr2/) indicates that there are at least 14 different module types/revisions of Corsair DDR2-800 / CL4 modules that utilize a wide range of different memory chips (Elpida, ProMos, Micron, Infinion, Powerchip, Qimonda, Samsung, Infinion etc.). Even though the superficial specifications for these chips appear to be pretty similar (DDR2-800 / CL5 / CL4), this does not necessarely mean that the modules will respond to the same operating conditions in the same way. There may be small difference in sub-timings/sub-latencies and/or the general responsiveness of the ICs which may affect the operating behaviour of the memory controller (which by the way also includes the PCI-Express interface which your video card is hooked up to).
And again: If running the system @DDR2-667 solves your issue, the possible explanation is that higher clock speeds may amplify (or trigger) potential performance problems that could have to do with the use of non-identical memory modules.
Furthermore: It is also possible that the memory controller's design limitations and the potential compatibility problems that may be attributed to mixing different modules types may reinforce each other in terms of reduced system performance.
3. The BIOS may have an impact as well
There has been known issue with the use of certain video cards in conjunction with 4GB of system memory on this mainboard:
https://forum-en.msi.com/index.php?topic=107301.0
https://forum-en.msi.com/index.php?topic=105955.0
https://forum-en.msi.com/index.php?topic=99818.msg798951#msg798951
What may have come out as graphics/display corruption in earlier BIOS Releases may come out as reduced system performance when using the latest BIOS Release. Of course, this is hard to prove, but I thought I'd mention it anyway. May I ask what amount of video memory your card has onboard?
Fortunately, there is a BIOS version that you could consider to try in this matter. It is not only the last BIOS Release that could be used in order to avoid the corruption issue, but it is (in my oppionion) the best BIOS Version that was ever released for the 975X Platinum PUE Mainboard: W7246IMS.716 [v7.1b6]. I have been using this mainboard for almost two years and have tested almost every BIOS Release that ever came out and I always went back to v7.1b6 as "ground zero".
It will properly support your E6600 (so you don't have to worry about that) and as far as I remember, there are no known compatibility issues with other components. So maybe, you want to give this a shot.
The bottom line is that in a worst case scenario, the problem you describe could be caused by all of the above things at the same time. You cannot really do anything about the 975X Chipset Specifications and the only way to rule out explanation #2 is to test modules that are actually identical (same model number, revision and memory chips). A test of the 7.1b6 BIOS Release is something you should consider. It may be the only way to test the BIOS Hypothesis.
This post turned out to be longer than I intended, but then again, I am well-rested after a good sleep and the wake-up coffee is kicking in pretty good.

- Have a look at metalink note 3951017.8 for a possible fix
- Check that your interconnect is properly configured
- Try running the query with PARALLEL hint. This would mean doing disk I/O instead of buffer & interconnect I/O.

Problem setting up data collection for a performance problem

We have a performance problem on our production environment: there is a query that is long to display specially on specific records involving a lot of détails. I had the idea to set up data collection to investigate the problem.
I used the wizard to set up data collection with default settings.
I had created a database PERF_DW on our test server for that purpose.
I didn't have any problem with the wizard: it created data collection sets and SQL Server agents tasks and probably many objects. But I don't know where I missed something but I didnt, have the chance to specify the database I wanted to tune
and even when I started data collection, I couldn't figure out where were the reports.
Then I tought that I did it all wrong so I stopped data collection and dropped the database and tried to deleted the jobs created and I had the following message:
TITRE : Microsoft SQL Server Management Studio

OK
Now I understand that the collectors prevent the jobs from being deleted but I can't delete the collectors.
What should I do?
Any help is appreciated.
Thank you for your advice.

Problem: Out-of-memory condition? : waiting for an available stack

Hello,
I'm evaluating jrockit and trying to run in ita java application that I normally
run with the Sun JVM on WinXP.
After a few seconds I get the message "Out-of-memory condition? : waiting for
an available stack".
I'm running it on an Intel machine, WindowsXP 392Mb RAM.
I have played with different GC options, heap, stack size, native/thinthreads
but it always stops around the same point. When I turn -Xverbose:codegen on I
can see that it's trying to compile a method in my own security manager. The message
is something like that:
[codegen] 500 84732 5169 de.irt.mhp.security.MySecurityManager.checkRead(Ljava.lang.String;Ljava.lang.Object;)V:

It looks as though it's in a loop.
This is the code for this method (the super class of the containing class is SecurityManager):
public void checkRead(String fileName, Object context) {
try {
if(context==null) {
super.checkRead(fileName);
} else {
super.checkRead(fileName, context);
} catch (SecurityException ex1) {
// If a file in the persistent storage is accessed we need to consider additional
MAC/DAC possibilities
ServiceDomainIdentifier sdi;
sdi=ServiceDomainIdentifierManager.getInstance().get(fileName);
FileSystem filesys=(sdi==null)?null:sdi.getFileSystem();
if(filesys!=null && !filesys.checkReadPermission(fileName)) {
throw ex1;
I also use many native methods in different libraries.
Any ideas?

Hello Staffan,
Thanks for the info. I had v1.4.1_05 and I have now installed v1.4.2_03.
Unfortunately, the error still happened at the same point in the code, although
much earlier on, but this time no message was displayed. It was just stuck there.
However, I changed the code a little bit (I put the catch block in another private
function) and now everything works. I'm writing the different snippets down. Perhaps
it would be interesting to find out why it behaves this way.
So, can you tell why this code won't works?
public void checkRead(String fileName, Object context) {
try {
if(context==null) {
super.checkRead(fileName);
} else {
super.checkRead(fileName, context);
} catch (SecurityException ex1) {
ServiceDomainIdentifier sdi;
sdi=ServiceDomainIdentifierManager.getInstance().get(fileName);
FileSystem filesys=(sdi==null)?null:sdi.getFileSystem();
if(filesys!=null && !filesys.checkReadPermission(fileName)) {
throw ex1;
But if I write it like following, it works!
public void checkRead(String fileName, Object context) {
try {
if(context==null) {
super.checkRead(fileName);
} else {
super.checkRead(fileName, context);
} catch (SecurityException ex1) {
myFunction(fileName,ex1);
private void myFunction(tring fileName, SecurityException ex1) {
ServiceDomainIdentifier sdi;
sdi=ServiceDomainIdentifierManager.getInstance().get(fileName);
FileSystem filesys=(sdi==null)?null:sdi.getFileSystem();
if(filesys!=null && !filesys.checkReadPermission(fileName)) {
throw ex1;
Thank you!

MAC OS X Lion performance problem - broken memory management

Starting with OS X 10.5 there are evident memory management problems in MAC OS X. The web was already then cluttered with complaints about system slowing down dramatically after some time. Back then i had slower machine, Mac Mini with 1GB RAM, so i (wrongly) concluded that it was due to inferior hardware.
Now i have 2010 MBP, core i7, 8 GB RAM, dual GPU.
Mac os X Snow Leopard was pain, but after migrating to OS X Lion, working some serious stuff on MAC started to be a nightmare.
I finally managed to reproduce the problematic scenario, so i run the test and recorded the screen, into video.
http://www.youtube.com/watch?v=u5wZwZh61_4
I run the tar+bzip command, which is basic unix stuff, on the large amount of picture files, in my Pictures/ folder. Just before start, i run the "purge" command, to delete inactive/cached program data.
You can see on the video that free memory starts to drop very fast, and inactive is constantly rising. If you take a look at "bsdtar" command, it takes only a fragment of RAM, so the problem is not in this process. You cannot say that it is a program memory leak, because then the problem would not be in inactive ram, rather in active/wired.
When the free memory dropped below 100mb, i started some apps, like Safari, iPhoto and MS Word, and you can see in the video, that it takes even minutes to start an app, when normally (when there is free RAM), it would take some 3-5 secs to load.
I run the same scenario and the same commands on my Linux Centos 6 box, no problem there ! Memory usage is some 10-20mb, no problems with cache/buffer.
The memory management must be very broken in Mac OS X !

Broken? That's a bit harsh.
Immature? That's perhaps a better explanation.
This paper describes Priority Paging as implemented in Solaris 2.7 back in 1998, and that's essentially what Mac OS X is in need of today:
The problem is that when pages are needed, no differentiation is made between system file cache pages and application pages, and worse, the file cache can actually steal pages needed by applications.
Finally when Dynamic Pager starts up and needs to start swapping things out, it's fairly heavy weight in operation, and causes the UI not responding cursor (aka the spinning beach ball) to appear.

Crazy problem with X-Fi ExtremeMusic. Desperate for He

I have done some research on this problem over the forums and haven't quite found the answer.
I have an Asus P5GDC Deluxe Mobo, P4 3.2 Ghz, GB DDR2 memory, Win XP sp2 with all updates. I have disabled the onboard sound card.
After inserting the X-Fi and starting the machine, XP finds the card and I install the drivers via the CD. After install, I am asked to reboot which I do. The machine comes up, card works great. When I am done, I shut down the machine. The next time I boot the machine, XP tells me it has found a multimedia audio device. When I go into Device Manager, the X-Fi has an exclamation point next to it under unknown devices. If I point XP to the location of the X-Fi drivers I am told they are not there. I reinstall the drivers and nothing happens. I usually have to uninstall the X-Fi drivers, reboot, reinstall, reboot and it works until I shut down and then the process starts all over again.
I am hoping someone can please help me with this because I have only a couple of patches of hair left to pull.
Thank you.

First install the Audiodriver from the CD. Then update your drivers. I could not install the updated drivers directly without having the same problems.

IMovie '11, still images as frames for time lapse problem

As strange as this may seem, I cannot find a way to change the stills I import to just be 1 frame each in iMovie '11. That is, I have 30 still images (a time lapse) that I want to put together for a 1 second sequence (i.e. 30 frames per second). The slowest I can seem to get is down to is 1 frame per second which gives me a total time of 30 seconds, which makes it useless.
Are still images able to be set to 1 image per frame? Am I missing something?
Thanks for any help you can provide.

You can do this in iMovie but it is quite cumbersome.
Long-time contributor Jon Walker created this Video Tutorial to show how to do this.
The Tutorial is for iMovie 08, but I verified that it still works for iMovie 11.
There are better tools for Stop Motion, including iStopMotion and QuickTime Pro. After doing it in iMovie, you may see why.

Performance problem with WPF Viewer CRVS2010

Hi,
We are using Crystal Reports 2010 and the new WPF Viewer. Last week when we set up a test machine to run our integration tests (several hundred) all report tests failed (about 30 tests) with a timeout exception.
The testmachine setup:
HP DL 580 G5
WMWare ESXi 4.0
Guest OS: Windows 7 Enterprise 64-bit
Memory (guest OS): 3GB
CPU: 1
Visual Studio 2010
Crystal Reports for Visual Studio 2010 with 64 bit runtime installed
Visual Studio 2008 installed
Microsoft Office 2010 installed
Macafee antivirus
There are about 10 other virtual machines on the same HW.
I think the performance problem is related to text obejcts on a report document viewed in a WPF Viewer. I made a simple WPF GUI with 2 buttons and the first button executes a very simple report that only has a text object with a few words in it and the other button is also a simple report with only 1 text object with approx. 100 words (about 800 charchters).
The first report executes and displays almost instantly and the second report executes instantantly but displays after approx. 1 min 30 sec.
And execute in this context means that all VB.Net code runs in the compiler without any exception or performance problem. The performance problem seems to come after viewer.Show() (in the code below) has executed.
I did another test on the second report and replaced the text obejct with a formula field with the same text as the text object and this test executed and displayed the report instantly.
So the performance problem seems to have something to do with rendering of textobjects in the WPF Viewer on a virtual machine with the above setup.
I've made several tests on local machines with Windows XP (32 bit) or Winows 7 (64 bit) installed and none of them have this performance problem. Its not a critical issue for us because our users will run this application on their local PCs with Windows 7 64-bit but its a bit problematic for our project not being able to run all of our integration tests but I will probably solve this by using a local PC instead.
Here is the VB.Net code Im using to View the reports:
Private Sub LightWeight_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)
        Dim lightWeightReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
        lightWeightReport.Load(Environment.CurrentDirectory & "\LightWeight.rpt")
        ' Initialize Viewer
        Dim viewer As LF.LIV.PEAAT.Crystal.Views.ReportViewer = New LF.LIV.PEAAT.Crystal.Views.ReportViewer()
        viewer.Owner = Me
        viewer.reportViewer.ViewerCore.ReportSource = lightWeightReport
        viewer.Show()
    End Sub
    Private Sub LightWeightSlow_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)
        Dim lightWeightReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
        lightWeightReport.Load(Environment.CurrentDirectory & "\LightWeightSlow.rpt")
        ' Initialize Viewer
        Dim viewer As LF.LIV.PEAAT.Crystal.Views.ReportViewer = New LF.LIV.PEAAT.Crystal.Views.ReportViewer()
        viewer.Owner = Me
        viewer.reportViewer.ViewerCore.ReportSource = lightWeightReport
        viewer.Show()
    End Sub
The reports are 2 empty default reports with only 1 textobject on the details section.

Performance problem in ABAP code

hai guys,
I created report using tables like bsis,t001 etc,( tax report).
I have performance problem in this report.
COuld you pls tell me how to analyse the report and find out the place where process is taking more memory etc.
i did abap trace and runtime analysis..but could not find out exact point.
how to do this..
i want to analysis each subroutine,internal table and query process.
could you pls give me some ideas.
ambichan

There is an excellent tool available in SAP - Code Inspector.

Transaction is SCII
Try the following link and I am sure you will find a bunch of useful documents.
<a href="http://www.google.co.in/search?hl=en&safe=off&q=site%3Asdn.sap.comfiletype%3ApdfCode+Inspector&btnG=Search&meta=">ABAP Performance</a>
I use the Code Inspector to search for
a) All the select statements which are present within the loop
b) Nested Loops
c) Select query without providing criteria for primary keys, depending upon situation
d) Can the search be narrowed with extra conditions
e) Using READ .. BINARY SEARCH if internal table has lots of records.
The list is actually endless, but this is something to start with.
You can actually have a checklist, and depending upon it, go through your code. The more you adhere to checklist, you will find that, the performance would dramatically improve.
Also use ST05 transaction, for SQL Trace and find out which select query is taking the maximum time for response.

Performance problems when running PostgreSQL on ZFS and tomcat

Hi all,
I need help with some analysis and problem solution related to the below case.
The long story:
I'm running into some massive performance problems on two 8-way HP ProLiant DL385 G5 severs with 14 GB ram and a ZFS storage pool in raidz configuration. The servers are running Solaris 10 x86 10/09.
The configuration between the two is pretty much the same and the problem therefore seems generic for the setup.
Within a non-global zone Im running a tomcat application (an institutional repository) connecting via localhost to a Postgresql database (the OS provided version). The processor load is typically not very high as seen below:
NPROC USERNAME SWAP RSS MEMORY TIME CPU
 49 postgres 749M 669M 4,7% 7:14:38 13%
 1 jboss 2519M 2536M 18% 50:36:40 5,9%We are not 100% sure why we run into performance problems, but when it happens we experience that the application slows down and swaps out (according to below). When it settles everything seems to turn back to normal. When the problem is acute the application is totally unresponsive.
NPROC USERNAME SWAP RSS MEMORY TIME CPU
 1 jboss 3104M 913M 6,4% 0:22:48 0,1%

Average 77.34 763.71 771.43 19680.67 0.00Making more memory available to tomcat seemed to worsen the problem or at least didnt prove to have any positive effect.
My suspicion is currently focused on PostgreSQL. Turning off fsync boosted performance and made the problem less often to appear.
An unofficial performance evaluation on the database with vacuum analyze took 19 minutes on the server and only 1 minute on a desktop pc. This is horrific when taking the hardware into consideration.
The short story:
Im trying different steps but running out of ideas. Weve read that the database block size and file system block size should match. PostgreSQL is 8 Kb and ZFS is 128 Kb. I didnt find much information on the matter so if any can help please recommend how to make this change
Any other recommendations and ideas we could follow? We know from other installations that the above setup runs without a single problem on Linux on much smaller hardware without specific tuning. What makes Solaris in this configuration so darn slow?
Any help appreciated and I will try to provide additional information on request if needed
Thanks in advance,
Kasper

raidz isnt a good match for databases. Databases tend to require good write performance for which mirroring works better.
Adding a pair of SSD's as a ZIL would probably also help, but chances are its not an option for you..
You can change the record size by "zfs set recordsize=8k <dataset>"
It will only take effect for newly written data. Not existing data.

Performance problems with File Adapter and XI freeze

Hi NetWeaver XI geeks,
We are deploying a XI based product and encounter some huge performance problems. Here after the scenario and the issues:
- NetWeaver XI 2004
- SAP 4.6c
- Outbound Channel
- No mapping used and only the iDocs Adapter is involved in the pipeline processing
- File Adapter
- message file size < 2Ko
We have zeroed down the problem to Idoc adapters performance.
We are using a file channel and every 15 seconds a file in a valid Idoc format is placed in a folder, Idoc adapter picks up the file from this folder and sends it to the SAP R/3 instance.
For few minutes (approx 5 mins) it works (the CPU usage is less then 20% even if processing time seems huge : 5sec/msg) but after this time the application gets blocked and the CPU gets overloaded at 100% (2 processes disp_worker.exe at 50% each).
If we inject several files in the source folder at the same time or if we decrease the time gap (from 15 seconds to 10 seconds) between creation of 2 Idoc files , the process blocks after posting 2-3 docs to SAP R/3.
Could you point us some reasons that could provoke that behavior?
Basically looking for some help in improving performance of the Idoc adapter.
Thanks in advance for your help and regards,
Adalbert

Hi Bhavesh,
Thanks for your suggestions. We will test...
We wonder if the hardware is not the problem of this extremely poor performance.
Our XI server is:
 Windows 2003 Server
 Processors: 2x3GHZ
 RAM: 4GB (the memory do not soak)
The messages are well formed iDocs = single line INVOICES.
Some posts are talking 2000 messages processed in some seconds... whereas we got 5 sec per message.
Tnanks for your help.
Adalbert

What are the best coding technics which will avoid performance problems

Hi Experts
What are the best coding technics which are avoiding memory problems and performance problems
Some times one of few reports are taking too much time to executing while handling large data.
1.What are the best way to declare a internal table to avoid performance problems.
2.what is the best way to process data.
3.what is the best way to clear memory.
Can you guys help me give some good suggestions for writing better programs to avoid performance problems.
Thanks
Sailu
