Slow Performance Topic publish method in 9.1 vs 6.1

We are migrating from WebLogic 6.1 to 9.1 and are currently running both in parallel. We will eventually shutdown 6.1 permanently once we are happy with 9.1.
          We have a severe performance problem in 9.1 that does not happen in 6.1.
          Using the same code in both versions, when a Topic publish method is executed in 6.1 it returns within 0.001 to 0.002 seconds no matter how mainy users are subscribed to it. But, in 9.1 the same method can take minutes to return, the more users that are subscribed to it the longer it takes.
          We have tried many JMS settings that we thought would fix this for us, but no luck. Our messages are non-permanent, and not transactional.
          I see in 9.2 there is a new feature called "one way send mode", we really don't want to upgrade to 9.2 just to see if this feature might solve our problem.
          As anyone come across something similar to this? any ideas?
          thank you

Hi,
          If anything 9.1 should perform faster than 6.1. Some random shots in the dark:
          - Perhaps the messages are persistent even though you actually mean them to be non-persistent. There's a "delivery mode override" configurable on the destination you can use to force messages non-persistent.
          - Perhaps paging is active in 9.1 but not in 6.1, you might want to tune your 9.1 paging.
          - Perhaps you used "MULTICAST_NO_ACKNOWLEDGE" on 6.1 but not in 9.1.
          - Check for stuck threads on the server (look at thread dumps).
          All that said, at least on the surface, it looks like you might be running into some kind of bug: you might want to contact customer support.
          Tom
          P.S. I don't think "one-way send" will help, as your problem seems to be on the subscriber side. How many subscribers are there?

Slow performance with javax.xml.ws.Endpoint.publish method

I've published an endpoint on my computer with the javax.xml.ws.Endpoint.publish method. When I'm load testing my endpoint on the local machine, with the client side in another jvm, the endpoint reacts very fast (server side(endpoint) and the client side on the same computer). There's not performance problem there.
But when I try to run a load test with the server side endpoint on my local computer and the client side on another computer the endpoint reacts slow, very slow compared to the local scenario. Instead of 500 requests / second I get like 3 requests / second. Why?
When I look at the traffic between the client and the server running on different machines it's like 4,5 kB/sec on a 100Mbit connection. And almost no cpu activity (neither server or client).
When I've a web server, like Tomcat or Sun Java Application Server and deploy my endpoint there the traffics goes up to 400kB/sec. So then it works fine with good performance over the same network, same ip address, same port and everything.
Why is my endpoint so slow when I publish it with javax.xml.ws.Endpoint.publish instead of on a for example Tomcat. And why is the endpoint fast when I'm running client and server on the same machine?

the timeout is a client side thing, most likely. you need to set the http request timeout on the client.

OCFS slow performance in ImpDP

Did anyone encounter slow performance using ImpDP on OCFS ? We have Oracle RAC 10.2g running in window connecting SAN storage and was formatted to OCFS. We compared the performance of running the same import in Local Drive (NTFS) and SAN storage (OCFS) and found that the time required to complete the import is 10 times than Local Drive (NTFS). Any tuning or troubleshooting that we could do ? Thanks in Advance.

Not aware of ocfs installing automatically when installing CRS/RAC. But then have never used Windows as a production o/s for Oracle. never mind using it to run RAC.
ocfs2 is the latest version as per Oracle's [Open Source project list|http://oss.oracle.com/projects/]. Am not aware of "ocfs 9" for 9i or "ocfs 10" for 10g on Windows.
What do you use ocfs for? Do you have the OCR and voting disks on the file system as files? Do you use it for Oracle datafiles too?
As for the SAN infrastructure being "+okay+" - there's more than that to it. You need some kind of driver on the o/s to interface with the HBA card.. where cables (dual 2Gb fibre?) run into a SAN switch and where the SAN switch is connected to the physical storage system.
A faulty cable can cause performance issue (e.g. reducing the dual path to the SAN via 2 fibre channels to a single one). There could be errors on the switch. The driver could be problematic (older version). Etc.
So there is a number of layers, both s/w and h/w, to check before going "+okay+". Trust that your infrastructure team is jacked up in this regard.
One method to benchmark the import problem is to use NT's performance monitor and monitor the import process. Not exactly sure how you would do it dealing with threads (as a thread in the oracle.exe executable will be servicing the import process) - but this should give you a somewhat accurate figure of the I/Os per second and bytes and blocks per second that the process is reading from the ocfs file system (assuming that you are writing it via ASM to raw devices).
At the same time you can monitor the process for other potential performance bottlenecks.
The only other factor that comes to mind that can impact ocfs performance is the ocfs cluster's communication layer. Like CRS that uses Interconnect for communication between nodes, so does ocfs. On a Unix system this is configured in the +/etc/ocfs2/cluster.conf+ file - and lists the number of ocfs nodes in the cluster and the network interfaces/addresses used for communication.
If this network layer is already quite busy, using it for ocfs2's cluster communication could be a problem performance wise.
You can test this aspect by unmounting ocfs2 (and stopping the ocfs2 cluster communication/heartbeat s/w too) on all but one node and then running the import. As there is only a single node in the ocfs2 cluster, the communication with other nodes is pretty much made redundant.
Last comment - ocfs2 is not slow as a cluster file system. It does a pretty decent job. And its performance is directly related to the h/w it runs on, and also how it is configured. That said, it is not a s/w component that really plays a role in Oracle CRS and RAC as ASM should be used (and is the recommended option from Oracle). ocfs2 at best can serve as a cooked file system for the RAC cluster (only used via directory objects in Oracle).

Extremely slow performance on projects under version control using RoboHelp 11, PushOk, Tortoise SVN repository

We are also experiencing extremely slow performance for RoboHelp projects under version control. We are using RoboHelp 11, PushOk and a Tortoise SVN repository on a Linux server. We are using a Linux server on our IT guys advice because we found SVN version control under Windows was unstable.
When placing a Robohelp project under version control, and yes the project is on my local machine, it can take up to two hours to complete. We are using the RoboHelp sample projects to test.
We have tried to put the project under version control from Robohelp, and also tried first putting the project under version control from Tortoise SVN, and then trying to open the project from version control in Robohelp. In both cases, the project takes a ridiculous amount of time to open. The Robohelp status bar displays Querying Version Control Status for about an hour before it starts to download from the repository, which then takes more than an hour to complete. In many cases Robohelp becomes unresponsive and we have to start the whole process again.
If adding the project to source control completes successfully, and the the project is opened from version control, performing any function also takes a very long time, such as creating a topic. When I generated a printed documentation layout it took an astonishing 218 minutes and 17 seconds to complete. Interestingly, when I generated the printed documentation layout again, it took 1 min and 34 seconds. However when I closed the project, opened from version control, and tried to generate a printed documentation layout, it again took several hours to complete. The IT guys are at a loss, and say it is not a network issue and I am starting to agree that this is a RoboHelp issue.
I see there are a few other discussions here related to this kind of poor performance, none of which seem to been answered satisfactorily. For example:
Why does it take so long when adding a new topic in RH10 with PushOK SVN
Does anybody have any ideas on what we can do or what we can investigate? I know that there are options for version control, but am reluctant to pursue them until I am satisfied that our current issues cannot be resolved.
Thanks Mark

Do other applications work fine with the source control repository? The reason I'm asking is because you must first rule out that there are external factors causing this behaviour. It seems that your it guys have already looked at it, but it's better to be safe than sorry.
I have used both VSS and TFS and I haven't encountered such a performance issue. I would suggest filing it as a bug if you rule out that the problem is not related to external influences: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform&loc=en

Very slow performance / format

How can i formate ???
OS taking so much time to set when started...
Slow performance very slow
Any solution?

See your performance is slow because the app you are using doesnt get enough memory or CPU. SO try to minimize the load off so that the requistite power goes to the app which you are tending to use. One such method is to open task manager. Then startup. Disable the app which you dont want to. Like I have disabled them. This would definitely power up your system. Try removing unwanted apps from your PC.

Printer redirection Slow performance

We have a Remote Desktop Server 2008R2.
When a user logs in (trough TS Gateway) with Printer redirection enabled (Using Easy Print method) the performance is very bad.
It's not printing that is slow, it's the performance of the RDP Session/server
For our test we disabled AntiVirus on the server.
Fox example: A user logs in with Local Printers, opening a small Doc file takes about 10 seconds. If the user logs of and logs in without local printers the doc file opens within a second.
Also generally everything is much faster without printer redirection.
The server is fully updated and we are using the most recent RDP Client.
The server is connected to an internet connection with 50/5 Mb Down/Up speed.

Hi,
I did a couple of tests:
- Step1: Removed all local printers, logged on with printer redirection enabled on the RDP client. Result: No performance problems with opening DOC files.
- Step2: Added printer 1, logged on. Result: Slow performance with opening DOC files.
- Step3: Removed printer 1, added printer2, logged on. Result: Slow performance with opening DOC files.
- Step4: Repeated Step3 with all printers. Result: Slow performance with opening DOC files.
So it doesn't matter which printer we add, it always results in slow performance. The printers are all from different brands. I happens with all user accounts, also with users that are Domain Admins.
OS:
RDS Server: Windows Server 2008 R2 Standard SP1
Client: Windows Server 2008 R2 Standard SP1
We monitored the CPU and Memory usage while starting Word, the cpu's doesn't use more then 4% utilization and the memory usage is low.
The Remote Desktop Services server has Office 2003 installed with SP3. We cannot upgrade Office to 2007/2010 because it's incompatible with our database.
Can it be that Word 2003 is loading the redirected printers while opening a document what is causing the slow performance?
Kind regards,
Bas

Win 2012 shared-nothing live migration slow performance

Win 2012 shared-nothing live migration slow performance
Hello,
i have two standalone hyper-v servers - A) 2012 and B) 2012 r2.
I tried live migration on non-shared storage between them. The functionality is alright but performance is low. The copying take a long time with max 200 Mbps.
I am not able to find the bottleneck. Network a disk performance seems to be good. It is 1Gbps network and when I tried simple copy paste the vhd file from A to B through cifs protocol, the speed was about almost full 1Gbps - it was nice and fast.
Is it feature? I am not able reach full network performance with shared-nothing live migration.
Thank you for reply
sincerely
Peter Weiss

Hi,
I don’t found the similar issue with Hyper-V, Does both of your hosts have the chipsets in the same family? Could you try to switch the three Live Migration Performance
Option method then monitor again? Or It seems there may have some disk or file system performance issue, please try to update your RAID card firmware to the least version.

IPad air slow performance

Hello there I bought a new iPad air 32 4g model and I have been noticing slow performance when opening a pictures of an app in the AppStore
knowing that I didn't face this problem an iPad 2 also I have restore the iPad air and still the problem is there

I had a 3rd Generation iPad on iOS 7.0.4. It's what I sold to buy the Air. It was terrible. I mean if the criteria you are using is efficiency and speed in moving around and using the OS, then it was terrible.
Safari was sluggish in scrolling with basic pages, closing apps, opening new ones, the Music app would take 4 to 5 seconds to open with a small library of around 12 to 15 artists. Tapping on items would result in a delay leading you to thinking you missed it and hitting it again.
I think the criteria you are using is "Did it work", then yes. Did it work well? Certainly not. It was a bit like Windows on an Intel Celeron CPU. it worked but drove most of us mad with how poor it performed.

UI: Matrix - Slow Performance, Urgent

Hi:
We are having problems with the performance of the Matrix.
We are developing with Visual Basic 6.0.
SAP Business One 6.50.50 SP:01 EF:07.
We are using DataBinding and UserdataSources to fill the Matrix because this is the best option, but the performance is slow.
We have a Matrix with 8 columns and we have problems with the performance of load rows into the matrix.
We load items and we have the below results:
For 1,000.00 Items or Rows the time is 7 seconds.
For 2,000.00 Items or Rows the time is 15 seconds.
For 3,000.00 Items or Rows the time is 20 seconds.
For 4,000.00 Items or Rows the time is 27 seconds.
For 5,000.00 Items or Rows the time is 34 seconds.
For 8,000.00 Items or Rows the time is 52 seconds.
For 10,000.00 Items or Rows the time is 1:08 minutes.
and we can calculate for 50,000 and 100,000 rows.
Our customers have 50,000 or more items.
Our matrix is into a windows that we are using for search items, and we need one faster method for dislay the items into matrix because this is a big problem now.
We want to know if the Matrix have limits of number of rows.
Some of our customers have 100,000.00 records on Item Master Records, with this performance the real time 113 minutes to load all rows into the matrix.
In a normal screen of SAP Business One we don´t have problems, but in our screen we have a slow performance.
What is the limit of rows into the Matrix ?

Hi Plácido,
I cannot give you a real good advice for 6.5
Running a select that fills a UDT + then displaying the content with DBDataSource will maybe not be much faster.
But in version 2004 this should be really fast as DBDataSources will be much better usable:
You can fill a matrix in one go (no iteration record be record necessary anymore) + you can access the contents of the DBDataSource + even add/remove lines!
This is only for non-system (i.e. B1) forms, but maybe could help you.
Maybe you should wait for that, if it could be a way to fulfill the logical requirements.

Frank

CS5 or Pc Slow performance?

Hi there,I have a problem with my pc at work and because I am not quite sure in which one is exactly the problem I decide to ask you.The pc is intel pentium 4 with 3 Gb Ram XP professional service pack 3 Photoshop CS 5.
The pc is connected to server(data base).When I open a bunch of photos (20-30) approximately 8 - 12 MB each one and sometimes I experience a slow performance(for example I am trying to retouch/clone something and it takes a lot of time for the pc to redraw/respond) the interesting part is that it doesn't happen always(sometimes can be even 3 photos and it will take ages to do something) also I notice that after appr. 20 minutes it's suddenly start to work as it should normally(it's like there was an update and when is updated/complete everything is fine).When that start to happen today I restart CS5 and load the same photos and it work fine, so it is really bizarre for me.I put a 89% ram usage to the CS5(I pretty much use only all the time Photoshop and bridge ) also made the history steps to 7 and the cache to 6 for big and flat files.I was checking the Efficiency and it's all the time 100 % so it's like it's not the photoshop but like I said today i just restard the ps and upload the same photos and got fix...I tried to copy the photos on my hard drive(so it should not be affect of the performance of the server but still the same as when I take them straight from the server.Because the hard drive is only 80 gb ( I don't store anything there ) i did clean up and disk defragment still the same situation.Do you know what can be the problem and is it the Photoshop or the Pc?I'll appreciate it.
Thank you

Could be that your PC is sometimes looking to check things on the server, and maybe the server or network is busy/bogged down and you PC gets caught in that cycle mess.....so,
suggest next time you use Ps, set win performance monitor perfmon.exe or perfmon.msc ; setup to view graph of disk use and network activity and cpu usage.....then you may see/track a problem area.
on win7, task manager does most of the same stuff

Slow performance of discoverer portlets

Hi,
I am running into slow performance of a particular page in portal, there are multiple sites hosted on the portal but these all have static text and are very quick to load but the one page with discoverer portlets and a web-clippping portlet is taking ages. If I run these reports on their own they are instant. Has anyone had similar problems with 9.0.2 portal and the discoverer reports ? I tried to identify a particular report that may be the culprit by deleting them one by one and to no avail. After a few hours effort I found the design mode was hanging as well. Again, just for this 1 page.
There are 3 tabs on this page with about 4 report portlets and 1 web-clipping portlet.
Thanks for any help,
Brandon

Thanks for the help.
Seems to have been resolved although I'm not sure if thats the end of the story. Will wait and see.....
So far apparently a port conflict of some sort in the discoverer config was causing it to hang and then also other system demands on the network and server housing the discoverer end-user layer were also causing problems.
No error messages unfortunately......

at all in event viewers for system, application, setup, no errors at all in DELL management tool, no hard drive errors, no controllers errors.... this server is replacing an old dell poweredge 2008 STD with 24GB RAM... the old DELL opens the same applications
way faster than the new one... same Quicken version; old server opens Quicken in seconds, new one 3-4 minutes..... Real time monitoring NEVER goes above 1% for CPU and 3% for memory utilization.... one more thing... removed antivirus 100% restart... same performance
without antivirus.....
Any ideas will be great as of how to troubleshoot the slow performance....
Thank you!

Slow Performance - Java Related?

This is an old box that I bought used recently, but the system install is recent. The system performs very slowly - about 50% of the speed of comparable Mac's in the XBench database. If I use Xupport to manully run "All" of the system maintenance crons I get some improvement, but it quickly goes back to being slow.
Looking at my logs I have a "boat load" of Java errors under CrashReporter; there will be a string of "JavaNativeCrash_pidXXX.log" entries - many of them, as follows:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : Bus Error occurred at PC=0x908611EC
Function=[Unknown.]
Library=/usr/lib/libobjc.A.dylib
NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.
Many of the line entries that follow, but not all of them, refer to SargentD2OL, which is a Java app, which I installed, but it did not work properly so I removed it. Yet I continue to get Java errors that refer to this now non-existant app.
I have read that Java apps use a lot of resources, and that D2OL in particular uses a lot of resources. Can my slow performance problem be Java related? If so, any idea of how I can fix this problem?
G4 AGP Graphics Mac OS X (10.3.9) 500 MHz, 512M RAM

Sorry to take so long to respond, but other issues in life have demanded my attention.
None of the solutions given have had any affect. My Java folder has both a 1.3.1 and a 1.4.2 app - the Java Update 2 will not reinstall because it sees an up-to-date app in the folder. But reading the update file it says the older Java will be removed - but it is still there. Problem?
On XBench the system scores a 9 to 10, while similar boxes on the XBench database score around 18 to 20. My cpu, memory, and video scores are very low. The HD through-put scores are the only ones that are normal. TechTool Pro 4 finds no problems. I have removed the memory sticks one at a time and retested after each cycle - no difference.
I have two drives, each with a 10.3.9 install. One works fine, scores around a 17 on XBench, the other scores a 9 to 10. So it appears to be a software problem. The slower install is a drive from a iMac G3 that has been moved to the G4 - are there issues with this?
My favored drive is the prior G3 one (newer and faster than the other drive that system tests faster in XBench) - it has my profile and all my info on it. It worked fine in the G3 - no problems.

Slow performance on a iMac 27" (maybe originated by the HDD)

Hello,
Well, I've had my iMac for 10 months now, but have never really paid attention to its performance since it was my first Mac and I was upgrading from a quite old computer, so it obviously proved to be a far superior machine.
However, I noticed the problem when I started to be more critical with my machine's performance (this triggered by the fact that I bought, some months after, a MacBook Air which flies beyond time and space). Curious about this, I requested a friend to do a benchmark test with Xbench resulting in his machine (another iMac 27” with comparable specs) clearly outperforming mine. Even the Air, with its slower processor and smaller RAM, has a relatively close performance.
Additionally, I have started to notice how the computer takes a long time to start-up and, after the desktop is “layed out”, it takes a lot of time before the machine becomes “responsive” (I usually try to start Mail and Google Chrome as soon as the pointer pops in!) with the final result that I have to wait in company of the beach ball for quite some seconds (half a minute) and even after the application had started, I can still hear the HDD working it as if there would be no tomorrow! And then, it is slooooow. Funnily enough, “tougher” applications like Photoshop or Illustrator don’t seem to have as many problems, relatively speaking.
A little bit on the background info: I have two partitions: one for Bootcamp (since I was migrating from Windows, I had some software that I wanted to use there: Matlab and Office, basically, and then some smaller Windows-only programs).
Derived from the benchmark test, I think I might have isolated the problem to the HDD (not sure though!).
SO THE QUESTIONS ARE:
1. How can I verify that the slow performance is due to the HDD being defective/badly configured/etc.?
2. Has the Windows Bootcamp Partition any effect on my machine’s performance under MacOS? (I would assume not, but you never know!). I have more than 1.3 TB free space left
3. What kind of corrective measures should I take?
4. Any other type of advice will be warmly welcome: I will try to do some PRAM and SMC resets but I am not counting on it. I had also ran the disk utilities and there were no permission errors (not so sure what this means, but I’ve read that it is supposed to be good news.)
5. Any extra info you might need, lemme know!
Greetz,
Víctor.
PS: Sorry for the loooong post. I tried to be thorough!

1. How can I verify that the slow performance is due to the HDD being defective/badly configured/etc.?
Run Apple Hardware Test: http://support.apple.com/kb/HT1509
2. Has the Windows Bootcamp Partition any effect on my machine’s performance under MacOS? (I would assume not, but you never know!). I have more than 1.3 TB free space left
Probably not but 1.3TB of free space left on the total HD is not enough for OS X, OS X needs a minimum of 10-15% free space! If you mean 1.3TB of Windows space I'd recommend posting that question in the Boot Camp forum.
3. What kind of corrective measures should I take?
If the drive is failing per the AHT then it's covered by warranty and will need to be replaced. Remember back up!!!!!!!!!!
4. Any other type of advice will be warmly welcome: I will try to do some PRAM and SMC resets but I am not counting on it. I had also ran the disk utilities and there were no permission errors (not so sure what this means, but I’ve read that it is supposed to be good news.)
Can't hurt, make sure you read the instructions carefully and execute the tests exactly as they are described for Intel based iMacs.
5. Any extra info you might need, lemme know!
If you no longer have a need for Windows on your iMac I'd recommend removing that partition using Boot Camp Assistant. That may correct your problems.
I would also recommend checking if System Preferences - Startup Disk and see if your internal HD is highlighted as the Startup Disk.
In addition I would recommend checking your Login Items (System Preferences - Accounts - Login Items) and delete any applications you don't need launching at Login.
