How can we analyze high CPU usage on JRockit ??

Is it possible to analyze high cpu usage through JRA recording ??
OS : Red Hat Linux
Or is there any other way we can analyze it .
Please let me know its urgent ....
Thanks in Advance

Hi!
It is indeed possible to use JRA to find out where the time is spent! The hot methods table in JRA shows where the JVM is spending the most time executing.
Kind regards,
Marcus

Socket and high cpu usage

Hi, am I using a multithreaded chat system: so a server and clients which can connect to the server.
The cpu usage is too high...probably because:
- The server is waiting for connections all the time
- The socket.getInputStream is continuously waiting for data
Running the server with: java -Xprof Server gives:
98% serversocket listening
82% socket.getInputStream reading
So probably the inputstream does this continuously:
is there data? no
is there data? no
is there data? no
and so on.
How can I decrease the cpu usage?

Are you sure that the inputstream doesn't look for
data?
So this doesn't happen:
is there data? no
is there data? no
is there data? no
is there data? no
No other threads are running. Just for each connecting
client a new Thread
Well, this does happen, but not in your program. This check
is usually done at OS level or hardware level.
BTW, how do you know that CPU usage is too high? Which tool
did you use to see the CPU usage?

Everytime time I try to upload a document or an image, it takes for ever and ever. I get a warning saying " High CPU usage by Firefox " How do I change this ? Can anyone explain ? thanks Lazarus 3

Mixer window can cause high CPU usage, crashes

This is probably one of the weirdest bugs I've seen for a while. Here are the steps that I reproduce it for me, maybe someone will want to try this out and see if they get the same.
1) Open an Empty Project template.
2) Create 16 instrument tracks when it gives you the dialog. (even 1 will be enough, but the effect is clearer the more tracks you create)
3) Open the mixer. Either in a window or in the pane.
4) Now create a "multi-timbral" instrument track with the plus button (use the checkbox there).
5) Select the 16th track, and now select one of the arrange tracks of the multi-timbral instrument.
6) Open up Activity Monitor from your Utilities folder in Finder and see how much Logic is taking up CPU. It should be significantly higher than the idle state. On my MBP it'll be around 80%.
This is not a problem in itself, because when reproducing it like this the high CPU usage goes away when you select another track and won't return if you select the multi-timbral instrument again.
However, I have sessions where this will continue happening with a multi-timbral instrument all the time. Not only that, I've had Logic crash when this starts happening. And this whole thing will slow down the UI considerably when it's active.
The workaround that seems to work for me is simply not keeping the mixer window/pane open.

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .
There is good post here in below link for this issue
http://thoughtsofmarcus.blogspot.co.uk/2013/06/leaving-password-blank-in-biztalk-2013.html
Another greate artcicle is by Nino which states these issues .SFTP adapter is protocol sensitive and some configuration by server side, can cause a lot of crazy situations

High CPU usage warning, how to fix??

Hey all -- First off, my laptop is brand new, and it is a Satellite C875D - S7120, using Windows 8. So far so good, everything seems to be fine EXCEPT...I am an artist and I have a couple of 3D programs installed. But every time I try to use them I get a "High CPU usage" error, like the art program is taxing the computer too much. I'm not a gamer... it seems to me that simple 3D imagery wouldn't cause this. But how do I fix it? I'm not that computer savvy...I've heard about registry problems but wouldn't have a blind clue how to get in there and fix anything... PLEASE ADVISE! -- Thanks in advance, Krystal

Ahh, Jerry, you are a friend in (my) need...will pounce on this ASAP! Twiddling around with this new device of mine is a challenge but also a learning experience. Probably the most important thing right now is NOT getting it 3D-ready but instead, teaching myself how to manage the innards...
Moki, someone on deviantART who is very skilled w/ Blender has said that they don't like the latest version because it is quite different from earlier versions. I haven't done anything with it in yonks, so once I get into it again, that shouldn't bother me. But it's true, "improvements" always seem to just weigh a program (any program) down instead of making it easier to use. That was why I have preferred older versions of some things instead of what's new out there, as the older ones are slimmer and not such resource hogs...
Disabling RayTracing...hmm! I shall definitely do that...plus try all the many other tips! *bookmarks page* I could even try that on this old XP, since I have Blender installed here also.
So if Toshiba is strong enough to handle graphics projects way beyond my modest little ventures (I doubt I'll be making movies anytime soon!), I ought to be able to get this puppy set up for it without too much trouble....let us hope....

need a quick opinion as i have another backbone abroad that uses only 5-10% of cpu usage.
- same config
- same setup (2BB for Sec/firewall, 2BB for Integration, 6Distro SW)
- different number of users
thank you and god bless.

I also agree with Stephan that this is not a concern that the cpu you are seeing it sohuld reduce down.
If in case still want to do the troubleshooting here is the procedure:
Here are some of the commands you can refer while you see the high cpu:
•1- Show proc cpu sorted | ex 0.00% >> First check whether CPU is due to Interrupt or due to Process Switching.
Eg: CPU utilization for five seconds: 6%/2%; one minute: 2%; five minutes: 2%
6% is total CPU utilization and 2 % is due to Interrupt. You would see this on a higher bit when you have the high cpu. Total-interrupt will give you the value of Process.
More info: http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a00804916e0.shtml
b) Show proc cpu history :---Check since how long is the CPU been affected.
2- Check if there is any interface drops are been seen:
show interface | include line|drops   ( Check if any vlan/interface are having input drops)
3- check if there are any STP issue:
show spanning tree detail
show spann det | in ieee|from|occur|is exec
show spann det | in executing | changes
show interface | include line|drops
show cef drop
show ip traffic   >> Check the traffic utilization.
4- There are some internal debugging which would help to find out which packets ( from Src,dst) is hitting the CPU:
debug netdr capture rx <<<<( DEBUG OF NETDR IS VERY USEFULL TO CHECK WHAT PACKETSS ARE COMING TO CPU)
show netdr capture-packet >> This will give you the captured outputs were you can see the Src and dst . Then you can take the action with those src ip address guys to check why they are punting the traffic.

SBS 2011 - High CPU usage - Help me Microsoft forums! You're my only hope!

My company supports a client that has a SBS 2011 server. For about the past year, we've been fighting a recurring issue with performance on this server. There are about ten local users and four remote users. The server's CPU idles at
about 60%-80% but is usally running when under *any* load from 80%-100%. If you do anything on the console, it will stay pretty much at 100%. These are not power users by any means. The server is utilized for file/printer sharing, Exchange
2010, and one flat file database application (non-SQL). SharePoint is not utilized.
Needless to say, our client is frustrated. When opening files, using their database application, or doing anything Exchange-related, there is a large amount of lag on the client side. First, here are the server's specs:
Make:Dell PowerEdge T420
OS: SBS 2011 Standard SP1
CPU: 2 - Intel Xeon E5-2407
Memory: 32GB
RAID: RAID 1 - Operating System (C:)/Data Volume (E:) | RAID 5 - Data Volume (D:)
Here is what we have tried to resolve this to finality:
* Doubled resources - Initially the server had a single physical processor and 16GB of memory. While these specs alone should have been fine, and were fine when the server was installed, we had periods of time where the server would just sit all day at
100% usage. We doubled the resources and while this seemed like it would fix the issue, we are still seeing abnormally high processor usage.
* Removed all monitoring tools, antivirus, and backup software - As part of our testing, we removed our monitoring agent (LabTech) and antivirus (GFI Vipre). Mozy is utilized for an off-site backup so that was disabled. No dice.
* Verified updates - We made absolutely sure the server was 100% patched.
* Malware/Virus/Rootkit checks - We have ran scans checking for any potential issues with security.
* Ran MBSA and MBCA to fix any issues with the server's configuration.
There is no single process which is using all of the CPU, or we would simply be able to narrow it down. Our calls to Microsoft support have yielded no answers. The last call ended with Microsoft stating that a SBS server should always be running
at high CPU usage. Meanwhile, we have many other clients with less-beefy servers, with more users, who have no issues like these.
So, I'm turning to you all. I will gladly provide logs, configuration settings, even remote assistance sessions if you all can help shed some light on what might be causing my issues.
Thank you!

Some comments/ideas:
How long was the server running after this screenshot? I ask because store.exe is only got a 1GB of RAM which is really low - it should grab most of the RAM within a few hours.
The server was up for about 12 hours. I believe an adjustment was made before to limit the Exchange memory usage.
Strange that SearchIndexer (wsearch service) is so high although that may be a startup condition.
The LT* processes seem to be a 3rd party monitoring tool - no idea why it would ever need that much CPU though (I thought you disabled this?).
We had, but we cannot go forever without monitoring our client's server. It has been pulled off in the past and results on performance are pretty much the same.
The taskmgr process run by amnet_admin has used a lot of total CPU Time. What is it? (can't see the command line).
That's the user I was logged in as when I took the screenshot. Even the task manager seems to eat up the CPU.
The sqlserver process right above it is also busy - may want to look at the command line and figure out which SQL database that is (SBS has 3 - WSUS, Sharepoint, and SBS monitoring)
I believe that's the SharePoint database. They don't currently use their site. Would you recommend a removal and reinstallation? I would not completely remove as I know SBS doesn't like you removing parts of the complete package.
Strange that vds.exe is 10% - that is the interface to the disk management interface IIRC. Perhaps your monitoring service has gone awry here - definitely lose it.
I'll see about pulling it off and I'll see if there are any improvements.

High CPU Usage on Terminalserver (Win2k3)

Hi,
at the moment we are running an Exchange 2010 SP3 in combination with Outlook 2010 (Ver. 14.0.6123.5001 32bit).
Outlook is installed on Windows 7 fat clients, but most users access their mailbox with Outlook running on a Win2k3 Terminalserver (extended support till 2016).
While the users on the fat clients don't have any problems, the thin client users experience problems with high cpu usage.
Following example:
Terminalserver, 12 users, 6 running Outlook, 2 users splitting almost the whole cpu between them (usage around 90-100%).
This makes working on that terminalserver nearly impossible.
I tried safe mode, I tried disabling their add-ins, I tried deleting their terminalserver profile to no avail.
How can I figure out what's causing this?

Hi,
Anti Virus email scanners are known to cause similar behavior, please first check if you have any Anti Virus scanner integrated with Outlook. Try to disable it, and check result.
A corrupted data file might also cause this kind of issue, try to repair your data file with Scanpst.exe tool.
Please refer to this article on how to use scanpst.exe:
http://office.microsoft.com/en-us/outlook-help/repair-outlook-data-files-pst-and-ost-HA102749454.aspx
Please also have a look at this thread, try the workarounds in it and see if issue persists:

High CPU usage

I'm using Vibe Desktop Version 1.0.1 (17445) on Mac OSX 10.8. During file syncronization there is a realy high CPU load:
Does anybody else see high CPU usage while using Vibe Desktop?

I'm the Novell developer responsible for Vibe Desktop and I'm sorry for the delayed response...I've been out of the office. Can you give me a little more information? I want to get a better feel for when the high CPU usage occurs.
Approximately how many files are synced to your Desktop?
When you click on the icon in the menu bar and select "Synchronize Now", how long does it take and how is the CPU usage? The first time you sync all the files down to your desktop can take some time, but once everything is in sync, forcing it to synchronize should not be very resource intensive. Is the high CPU utilization only when it is has files to download, or is it also high when there is nothing to download?
When Vibe Desktop is not syncing, it's still watching the file system for changes you make to the local copies of the files. Do you see noticeable CPU utilization when Vibe Desktop is not syncing?

High CPU usage - Rapid Battery Drain - Running HOT

Looking for help.. PLEASE!
Z10 - Model STL100-3 Software release 10.2.1.2179
Symptoms;
Occasionally, and for no apparent reason, I notice my Z10 getting hot in my pocket. I run the device monitor App and see a very high CPU usage, which consequently drains the batter very quickly.
I've tried all the solutions from every support group thread and blog. And I mean ALL!
Pulling the battery
Replaced the battery
Removed the SIM
Deleted G Mail
Removed all 3rd party Apps (2)
Stopped email sync
Stopped calendar sync
Turned off all radio
Turned Off Wi-Fi
Let it sit for hours, even days to let it finish doing whatever its trying to do
Etc Etc Etc.
Finally, I called BB support, they wanted $50 to talk to someone. I told them the issue, they said the device is bad and must be replaced. I said its software related!! They said.. no, its a hardware issue. Device is under warranty and they want me to just go get a new one. I don't want a new one, I want a fix! Stop the waste of BB $
Temporary solution
Eventually, I decided I would do a restore, back to the factory settings, and here's when I found something
I run BB Link, connect the device, do a back-up... and LOW AND BEHOLD.. this fixes the high CPU usage and the device runs great, very cool, low cpu and extremely long battery life.
Sadly! .. this problem reoccurs, after a few days, sometimes after a couple of weeks and just out of the blue.
I can force this fault to occur, simply by doing a restart of the device. Sure enough, it will run hot, use all the cpu and I will have to do a back-up to get it to settle down again. I've tried to wait for the so called 'indexing' to finish, but it never stops running with high cpu and doesn't help.
Can any one tell me whats happening and how to make this a permanent fix?
There are hundreds if not thousands of people having very similar issues, and many different methods to fix it. Its my belief that there is an underlying bigger problem that relates to all these differing fixes, but as yet.. I cant find it and none of these fixes work for me. For now... I will keep doing the occasional back-up and hope I get a response that can help.
Thanks to all that read this.

The heat may be normal. After a little water damage incident, which I repaired, I disassembled my Z10 the find a small heat sink will thermal compound. This helps dissipate heat efficiently. I found a large number of air bubbles and possibly a large air pocket by the way the paste stuck to both sides. I removed the old paste and replaced it with artic silver paste and the z10 has been much much cooler. It use to run about 105*f and now it is around 85*f.
See this thread I posted for before and after pictures using a thermal imager.

@Curve8530 .....as much a s your discovery is appreciated, I hardly believe that most people will actually dismantle their phone to remove the paste and replace with arctic silver. Besides, what you are doing is not a fix for the actual problem....
In most cases, this heat is associated with apps using the CPU resources beyond the normal limits.
As an easy fix, finding and removing the app(s) in question followed by a reboot, solves the issue. In some cases an OS reload is necessary.... but under no circumstances I would even remotely suggest to any member to dismantle their phone and do what you did...

High CPU usage (more than 100%) while running video applications

Hello everyone,
I desperately need help with this.
I have a late 2007 White Macbook running Mac OS X 10.6.8 :
Model Name:          MacBook
Model Identifier:          MacBook2,1
Processor Name:          Intel Core 2 Duo
Processor Speed:          2 GHz
Number Of Processors:          1
Total Number Of Cores:          2
L2 Cache:          4 MB
Memory:          3 GB
Bus Speed:          667 MHz
The issue that I am having is, whenever I play a video (Netflix/Silverlight player, YouTube, Skype, etc.) the CPU usage shoots up above 100% and the video or the video chat becomes VERY choppy. It becomes impossible to keep going once that starts. Originally I had 1Gb RAM (512 + 512) ... then I upgraded to (1GB + 512mb) ... it was fine for about a year and then started chocking on memory... so recently I made it (1GB +2GB) and that's when this high CPU usage thing started (according to my knowledge)
I have had this machine since last 4 years and its very dear to me. I dont wanna buy a new one. I will really appreciate if someone could help.

I am spending sleepless nights, researching for a fix. From what I found so far, a considerable amount of people were able to fix this issue by simple cleaning the insides of their machines using air dusters, especially the fans. I don't know how cleaning would help with CPU utilization, but by interpolation, I feel it's worth a try. At least it will be clean, if not perfectly functional. lol
Now the next big challenge ahead of me is getting the screws on my Macbook open. I was following the Fan Repair Guide on ifixit.com. I went and got the #00 Phillips screwdriver as suggested in the guide... came home and found out the screwdriver is too big.... went back got a #0000 Phillips (I also found out that screwdrivers with same number might be of different sizes in different stores)... got a couple of screws out and then--- another road-block!! there are a few extremely tiny Phillips screws on my macbook. Now I am hunting for the smallest Phillips screwdriver in the world. Hopefully, I will find it in some watch repair or eye-glasses repair kit in a store such as CVS or Walgreens... aaaah... this is sooo frustrating!!! I just want to get his done so that I can check it off the list of probable solutions that I want to try. Will update here if this works.
From what you say, I think that the Silverlight upgrade might be the culprit in my case too. But the effect is there also for Youtube, Skype , or any other Video/Graphics intensive application that I use. Although, Silverlight/Netflix performs the worst among all the apps.
I love my Macbook... don't want to part with it.

Skype 4.2.0.11 has abnormally high CPU usage while...

Skype 4.2.0.11 has abnormally high CPU usage while idle.
I can't get my laptop under 70 degrees celsius unless I cpulimit or quit skype, and cpulimiting it actually makes it completely unresponsive, as if some other thread is constantly generating a lot of work and taking priority over the UI thread.
What the heck is skype doing? (And why do any of its threads need nice -10?) It takes up more CPU time than pulseaudio, truecrypt, and deluged combined.
Its CPU usage is constantly between 5 and 50 percent*, it's absolutely horrible.
*While idle. I'm unable to make calls.
I know this is expected from a linux user, but for all I know, Skype is malware. It's not open-source, so I can't find out for myself, and there are no open-source alternatives so the frankly shameful amount of bugs I encounter in Skype will never be fixed.
There are several bugs I'd love to be fixed in Skype, but first, PLEASE, optimize your code. It's absolutely horriffic at the moment.

Attached are statistics from my desktop over approximately a 24 hour period for the processes shown (other than firefox and adb).
Pulseaudio tops skype this time but that's because I've had music playing through mpd for a few hours. Skype uses more than 16 times the CPU that pidgin does, and almost double the RAM! RAM isn't shown in the screenshot but take my word for it. Bear in mind that I haven't taken (or made) any calls in this period of time, and pidgin has been signed into three different services and using encrypted chat.
I really wish that at least the protocol would be documented so someone could work around this, at the moment I don't think the guys writing skype realize just how unstable the linux port is. At least it's better than the Android port.
[Edit for those unfamiliar with linux processes: "TIME" is the cumulative time that the program has been scheduled for on any core, effectively making it a measure of total CPU usage for a given time period]

High CPU Usage with Flash Player 11

I am not sure what the problem is but ever since I had those issues I went back to flash archive and installed a previous version that did not come with the flash plug in and I never had any problem with it since I am currently using the Adobe flash version 10 plug in with an adobe flash player active X. and I find out it was the new flash plug in that is the issue it suck all your ram. If you get some people who is having the same issues where flash player is duplicating and eating all their ram then ask them to try the version 10 plug in with the flash 11 active x it will work fine. I tried to run the version 10 flash as a complete set but some dynamic site that plays videos require a later version of flash active x to work and will be asking for an update however by keeping the flash 10 plug in there won't be any other issues. Adobe need to find out what is wrong with the new flash plug in and run a comparison with the flash 10 plug in. I hope this will help some user to get over the issues that made my online experience a nightmare for a while too.

The best way to get a resolution is to address your individual issue. Your complaint is that RAM usage is high, which is unrelated to the thread from the guy on Mac that was seeing High CPU usage on high definition video.
In order to fix the issue that you're describing, we need to be able to reproduce it. Please provide the information below, and the results of the basic troubleshooting steps as you work through them. This will help us narrow down the root-cause, and allow us to find comparable hardware in our compatibility lab to reproduce the issue with.
Basic Troubleshooting Info
To help troubleshoot we'll need the following system information:
- Operating system
- Browser
- Flash Player version - http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
- Antivirus/Anti-Malware software and versions
The first step is to work through the video troubleshooting guide for your operating system, here:
- Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html
- Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.htm
When reporting issues with video or audio, it's also helpful to get your system hardware and driver details. Instructions for finding this information can be found here:
- Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Windows_users
- Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Mac_OS_users
Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player. I recommend trying both of the links below to see how they perform. If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing. You can verify this by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the menu.

Unusually high cpu usage with iMovie 6.0.3

I'm having trouble with very high cpu-usage. Just the open imovie app is taking up about 50%, during playback it sometimes peaks over 100%! The project file is pretty big (about 30 gig), but that is mainly because of the amount of footage imported into it. The movie itself is about 25 minutes in length. There is some audio editing going on: some soundeffects, musicfiles (no drm-protection), audio commentary that i recorded within imovie. I know that imovie has trouble when there is a lot of audio/audio editing involved and this project is probably a little more complex than other stuff i did in imovie, but i never had such problems. i can hardly use playback anymore. I recently updated Quicktime to 7.6.4 and Perian to version 1.2.1. Any ideas what's going on or how to work around the problems? Since the movie is about 80% finished i don't really want to start all over again. Thanks in advance for your input!

Hi Klaus1
I have several plug-ins by cfx and the slick volumes 4, 6 8 and 10. I can post a list of all of them if you like. Up to now they never made any trouble, but you'll never know...
The edit in the timeline is about 25 minutes long. But the project file contains captured dv-footage of about 2 hours, so that alone adds up to something like 26 GB. Then there are a few rendered effect-clips done with some of the plug-ins like stabilizing or color correction which also add to the 30 GB, as well as some audio-files (some music, my voice-over commentary). I emptied the trash several times while working on the movie. At this moment there are only a few MB of erased audio in it.
It all sounds a bit like this is an insanely huge and complex project, but as i said, i have done projects like this in imovie without the massive cpu-usage. I'd like to continue to use imovie, but if this problem keeps coming up with future projects, i might as well take the step and switch to Final Cut Express.
For now I will try your idea of exporting the movie as it is now and open it in a new project file.
Thanks for your help and input so far!

Kernel_task high CPU usage yosemite

Hi,
I have a problem with my old macbook pro 15" Early 2011
The battery was dead so I bought a new one and replaced it. I also installed a new Samsung SSD.
Then after the startup (OSX Mavericks was installed) I had a high CPU usage on the kernel_task process.
After some research i managed to get rid of the problem with manipulating the IOPlatformPluginFamily.kext files.
After that everything worked fine.
Now I decided to upgrade to Yosemite (clean install from usb) and now i have the same problem again, but i can't find the IOPlatformPluginFamily.kext.
After I power up the macbook everything works fine, but after some minutes the kernel_task has again a very high CPU usage - the mouse is hardly moving.
How can I solve this problem and where do I find the IOPlatformPluginFamily.kext? Is there another solution for this problem?
I already reset the SMC and the NVRAM.
thank you
Hans
