CPU Load not balanced

hi,
I'm having trouble figuring out why one of the cores in my server is carrying most of the load.
I run Oracle 11g R1 on Oracle Unbreakable Linux 5. The server has a quad-core CPU. Core 1 is at 17%, Core 2 is at 100%, core 3 is at 5% and core 4 is at 5%. I wanted to see if someone could help me to find out why all the load seems to be going to core 2.
I appreciate any help I can get.
Newbie.

Hi,
Maybe this is a better example of the CPU with a moderate load:

AFP-High CPU Load-Not Using Home Directories-10.5.6

We recently rolled out a Leopard File server (AFP, SMB services only) this past Monday using 10.5.6. We have about 30 AFP and 15 SMB users. We have 5 Apple XRAIDS connected through a Sanbox 5200 switch to the Leopard server. We are not using home folders for the users.
Similar to some users in this article (http://discussions.apple.com/thread.jspa?threadID=1685965&tstart=0), I have noticed an increase to 100% CPU usage in just a few hours, and the second day 200%. Although the server does keep allowing new logons, performance is being affected. As noted by others, manually disconnecting all active or sleeping connections does not lower the CPU usage.
I though that following the suggestions in this article (http://support.apple.com/kb/HT1765) about disabling Allow Host Cache Flushing in the XRAID performance tab would help, and it did, but just for a short while, and then at about noon, when the XRAID had been accessed for about 6 hours, and the 20th AFP user logged in, the CPU usage spiked back to 100%.
I am wondering if this is related to the number of AFP connections (more than 20), or if I have some client machine causing havoc when it logs in.
Here's my XRAID configs:
Use Controller Write Cache
Not Allow Host Cache Flushing
Use Drive Write Cache
Read Prefetch: 8 stripes (512 KB/disk)
Fiber Channel:
Speed: Automatic
Topology: Automatic
Firmware: 1.5.1/1.51c
At this point, I really am stumped as to why the AFP service won't let go of the CPU, even when users are kicked off. I haven't added any of my XRAID shares to the private portion of Spotlight, but the volumes have already been indexed long ago, and since then I've rebooted several times, and not many new files are getting created any way.
At any rate, I don't think this issue has anything to do with Home Directory sharing, as I'm not using them.

I'll also mention that most (95%) of our clients are still using Tiger 10.4.11. We have very few Leopard clients (10.5.5 & 10.5.6).

How to Show Real CPU load, and not just Average Load on Server Performance or CPU metrics

Hi There,
we are currently using application insights for one of our customers, and they have raised the question with me, regarding CPU spikes. Is there anyway to show these when viewing the server performance or within the CPU metrics?
The reason for the question is that for our particular application the average CPU load is 4%, however when viewing task manager real time, I can see spikes go anywhere from 20-60% for a second or two.
Also do you know if the ability to grant user access to the likes of our customers so they can see the results so I don't have to send screen shots etc. on request.
Any help on this would be greatly appreciated.
Best Regards
Antony

Problem... High CPU load with HDD. Please Help

Hello all,
Im stuck. Ive got a MSI KA790GX which has poor HDD access/transfer, low burst rate and very high CPU load.
As far as i know the Western Digital 640gb WD6401AALS Black should be a fast hard drive. Which according to reviews/HD Tune,
should be:-
Minimum 60mb/sec
Maximum 120mb/sec
Average 95mb/sec
Access 12ms
Burst 110mb/sec
CPU 5%
No matter what I try, i always get poor results...
My MSI KA790GX
Minimum 41mb/sec ~ 54mb/sec
Maximum 104mb/sec ~ 108mb/sec
Average 86mb/sec ~89mb/sec
Access 12ms
Burst 60mb/sec ~ 80mb/sec
CPU 26% ~ 44%!!!!!!!!
I could accept not getting the same high speed results as the review/reference, even if the burst rate sucked.
But one of the cores goes to 50%-60% load during hdd activity. Thats just crazy!!
I have tried...
IDE mode, AHCI, RAID Ready, RAID Single Disk
SATA Port 1, 2, 3, 4 + 5
Different SATA cables
Flashed bios, cleared bios, optimised defaults, failsafe defaults
Windows XP 32bit, Vista 32bit, Vista 64bit. fresh installs
MSI CD Drivers, MSI Web Drivers, AMD/ATI Web Drivers
... and combinations of.
I have also tested the WD640gb Black on another older PC, with Nvidia (55?) chipset and slower (1.9ghz x2) cpu.
Transfer rates were slightly better than my KA790GX but, Burst Rate = 115mb/sec and CPU usage = 13%.
I also tried a Seagate 1.5tb (ST31500341AS) on both PCs,
Nvidia chipset
Minimum 65mb/sec
Maximum 134mb/sec
Average 107mb/sec
Access 14ms
Burst 83mb/sec
CPU 7%
On my MSI KA790GX
Minimum 55mb/sec
Maximum 120mb/sec
Average 100mb/sec
Access 14ms
Burst 87mb/sec
CPU 33%!!!!
Could someone please please help, ive spent hours and hours on this. Its doin my head in.
I just hope its something stupid ive missed, cos i still not used my HD4850 from christmas :-(
Thanks.

Not sure how to check PIO/DMA mode on a SATA device. IDE devices show DMA enabled.
BIOS version 1.4 - 29 December 2008, and now version 1.51
Fredrik
I have Vista 64, but i did try XP32 and Vista32 and got similar poor results.
I tested HDD speed with, HD Tune 2.55 and HD Tune 3.50 trial.
No auto-start programs really, Windows clean installs + any drivers.
Quadrifoglio Verde
CPU @ default 2800mhz, All mem bios options to auto/defaults
Windows Experience Index, CPU Score = 5.3
AMD Overdrive
Integer Computation = 8220
Floating Point Computation = 5325
Memory speed = 1770
Cache Speed = 10790
System Performance = 7403
Bas
I used HDTune because I could reference to other results. Whats a better program to use?
Windows Experience Index, HDD Score = 5.9.
But I have no reference and cant be sure of cpu load.
Sepher
Bios defaults to C&C and C1E off so i have tried them. Also windows power settings, balanced/high performance.
UPDATE
Reinstalled Vista64 but loaded the AHCI driver from the disk config screen. This seems to have stopped the high cpu usage during disk activity.
HDTune with Windows Power settings @ High Performance,
Min = 52mb/sec
Max = 106mb/sec
Ave = 88mb/sec
Access = 12ms
Burst = 77mb/sec
CPU = 3.4%
HDTune with Windows Power settings @ Balanced
Min = 54mb/sec
Max = 104mb/sec
Ave = 87mb/sec
Access = 12ms
Burst = 65mb/sec
CPU = 12%
So now transfer speed is about 10% slower than reference. But burst speed is terrible.
I also used IBM Feature Tool to change the HDD AAM to 'performance mode' 254 as suggested elsewhere.
Long shot as the hdd performs ok with other hardware. same results.
Also MSI support asked me to try a newer bios, version 1.51. same results.
Anyone know what the AMD 7-Series Chipsets Disk Performance Utility does, and should i run it in Vista64?
Thanks for all the replies, hope i can sort this, not played any PC games since Quake 3 on my ti4600...

J2EE Processes using 25% CPU load without load

Hi
We are running a Portal cluster with 2 cluster application nodes with each 2 J2EE server processes and a dispatcher.
We experiences that after some time the J2EE server processes can start using typical 25% CPU without any load on the portal - after some time the load typically increase to approx. 50% CPU (still without user load) and the only "solution" is to restart the processes.
Anyone you have experienced a similar behaviour?
BR
Tom

Are you doing load balancing too somewhere?
I though I read somewhere about some replication between nodes that goes on. If they transfer their information and drop it, that is fine. But they don't. On the next round they exchange the new info and info from the last time. It just grows. Look at you DB server, check to see if one of the DB's grows with the CPU load.
The other thing is logging. I am a log freak myself but, sometimes I get into trouble by logging too much. Next time your CPU loads check *.log and temp logs, see if there are any over 10 gig.
Not that I never had one,
no,
never.

90% cpu load on ubuntu 8.04

Hello all,
I made a visualization for sorting algorithms. (The code is to long to post it here)
I developed the app under this system:
Windows Vista Home x64
Dualcore ~2.6GHz
Java Version: 1.6.0 Update 7 32bit
and i have a cpu load of ~10% when i run the app.
I asked my friend to test the app under his OS:
Ubuntu 8.04
Dualcore ~2.2Ghz
Java Version: 1.6.0 Update 7 32bit
and he got a cpu load of over 90%!
We both had no running tasks in background. It was only the java app.
Are there any known issues about this problem or could could it be a coding problem?
Btw the programm uses round about 8 Threads.
TIA

But with the sleep time it's just 1 or 2%.
I want to know if there is a known issue in the JVM that causes threads on some systems to use to much cpu load.
Or could it be a coding problem?
What do you think about the sleep time in this loop?
Or could the high cpu load be caused by bad coding?After reading this post I could not read further. There is the problem. You're doing a sleep(1) .....
Even in C that will most likely kill any cpu. Try to use joins: elegant and faster ;)

How do you spread CPU load over more cores?

Hi
I recently bought a macbook pro quadcore i7 because my 2007 macbook couldn't cope with the demands of Logic when using it rewired with Ableton Live, and had lots of CPU overload messages.
I am really disappointed that having spent so much money to overcome this problem, it has only slightly improved the amount of overload messages. I read the article below about how to spread CPU power over the cores, now I have 8. I still can't figure out though how to control which channels are using which core and spreading the CPU load to cores 5-8 which don't seem to be being used. Any ideas?
Can I rewire from ableton to different cores?
In my project, the 2nd core keeps overloading whilst the others are down. Is it to do with aux channels, master channels, buses etc?
Or should I upload my memory to 8GB RAM?
Thanks
Steve
Here's the article:
About core activity
Logic breaks tasks down into threads that can be assigned to a single core for execution. It's not possible to split a single thread across multiple cores, although a single core may run multiple threads at the same time. This is one reason that you may sometimes see uneven load distributions across the available cores on your computer. If one thread is very processor-intensive, the core running that thread may show much more activity than the cores running less demanding tasks. This is the main reason that you may get "Core Audio Overload" warning messages even though some of the cores on your system may not show significant activity.
To monitor Logic as it uses the cores on your system, double-click the CPU meter in the Transport area.
A window displays a meter for each core.
The same concept applies to channel strips as well. Each channel strip—and all plug-ins it contains—is processed by one core. If you are using many processor-intensive plug-ins on a single channel strip, the core running it may show heavier activity. This is especially true if you are working at high sample rates (88.2 kHz or higher).
Redistributing core loads
If you find that a single core has much higher activity, use these strategies to redistribute the load.
In the example below, there is a single Software Instrument channel strip with plug-ins routed directly to Output 1-2. The channel strip for Output 1-2 has a large number of plug-ins.
In this example there is activity on two cores: the left core is handling the Software Instrument while the next core processes the Output 1-2 channel strip. You can use routing capabilities in Logic to distribute the load to more cores without changing the sound, as in the next image.
The resulting signal chain is Inst 1 > Aux 1 > Aux 2 > Out 1-2, as shown in this table:
Channel strip
Input
Output
Inst 1
Bus 1
Aux 1
Bus 1
Bus 2
Aux 2
Bus 2
Out 1-2
Also, the first four plug-ins have moved from Output 1-2 to Aux 1 and the remaining four plug-ins to Aux 2.
After adjusting the volumes to the respective channel strips appropriately, the result sounds identical, but now the load is distributed among four cores instead of two. You can use this concept to redistribute plug-ins from Audio channel strips, Software Instruments, Auxes, and Outputs (as in this example).
In the image above, there is still a very heavy load on a single core, even though it's using the routing described above. Notice the Inst 1 channel strip is selected. When a Software Instrument track is selected in the Arrange window, Logic enters "Live Input Mode". In this mode, Logic turns on every plug-in in the channel strip's signal path so the channel strip can be played live from a MIDI controller. All of this must be handled by a single thread and therefore just one core. It's a good idea to keep a track that uses an Audio channel strip selected in the Arrange window, unless you're actively playing or recording to a Software Instrument.

OS X Snow Leopard introduced Grand Central, where the OS will distribute the load better to more cores, however it takes time for software to adapt to these changes and make a rewrite of the codebase and test it out, Apple's included.

Kernel_task running above 500% CPU load on my Macbook Pro running OSX 10.9.4

I recently upgrade my Macbook Pro to OSX 9.0.4 and the system is running sluggishly slow, Activity Monitor showing kernel_task always running above 500% CPU load, system fan always running loud at startup but laptop is not overheating. Below is the EtreCheck report, hoping if anyone can help me fix this issue, much appreciate it. Btw, I have done the SMC reset, but nothing has helped.

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

Hwmond high cpu load after 10.6.8 update

hwmond is causing up to 70% cpu load after every reboot on several xserves i manage caused by the update to 10.6.8. anybody else having this problem? it can be solved by hwmond -s5 to set the hwmond interval to 5 seconds but this command is not processed properly, is causing an error message "IOConnectMethodScalarIScalra0 call return err = 0xE00002BC" and has to be exited with cmd+c. Also, the com.apple.hwmond.plist in LaunchDaemons is empty.

In my case:
I installed 10.6.8 via the Combo Update, was running 10.6.7 previous to this.
/System/Library/LaunchDaemons/com.apple.hwmond.plist still exists and is not empty
/etc/hwmond.SMART still exists and is not empty
/etc/hwmond.conf didn't exist, so from Terminal.app I simply issued "sudo touch /etc/hwmond.conf"
I tried:
In Terminal.app, ran:sudo launchctl unload /System/Library/LaunchDaemons/com.apple.hwmond.plist
Then, backed up /usr/sbin/hwmond and /System/Library/LaunchDaemons/com.apple.hwmond.plist
From a Mac Pro running 10.6.7 Server, copied both the binary and the plist to the same spots on the Xserve, then, in Terminal.app, ran:sudo launchctl load /System/Library/LaunchDaemons/com.apple.hwmond.plist
That didn't change a thing. hwmond still spiked.
Put everything back the way it was.
And:
In Terminal.app, ran:sudo launchctl unload /System/Library/LaunchDaemons/com.apple.hwmond.plist
Backed up /System/Library/LaunchDaemons/com.apple.hwmond.plist
Made another copy to the Desktop
Edited this copy and added a string in ProgramArguments with a value of "-S255", but this still caused hwmond to spike after putting this copy back in LaunchDaemons, repairing permissions, and loading the plist via launchctl again. Any valid value still caused it to spike. However my Xserve now reboots if I set the value to an invalid value, like "-s256". Then again this also caused com.apple.hwmond and com.apple.launchd to create entries in the system log complaining about the value with hwmond attempting to relaunch itself every 10 seconds:
6/24/11 2:37:10 PM com.apple.hwmond[2697] hwmond: n should be 1 to 255 seconds
6/24/11 2:37:10 PM com.apple.launchd[1] (com.apple.hwmond[2697]) Exited with exit code: 1
6/24/11 2:37:10 PM          com.apple.launchd[1] (com.apple.hwmond) Throttling respawn: Will start in 10 seconds
OP, Armin, did something similar, but I think he tried doing it directly in Terminal, not using launchctl / launchd, which caused the error he mentioned.
Finally, added a "Disabled" item, with a boolean value of YES to the plist, recopied it, repaired permissions again (launchctl will complain and won't load the plist if you don't). This way hwmond is disabled, I can reboot my Xserve, and wait until Apple figures this out.
Full com.apple.hwmond.plist on my Xserve looks like this now:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
          <key>Label</key>
          <string>com.apple.hwmond</string>
          <key>OnDemand</key>
          <false/>
          <key>Program</key>
          <string>/usr/sbin/hwmond</string>
          <key>ProgramArguments</key>
          <array>
                    <string>hwmond</string>
                    <string>-s255</string>
          </array>
          <key>ServiceIPC</key>
          <false/>
          <key>Disabled</key>
          <true/>
</dict>
</plist>
Edit: I too have filed a bug report with a link to this thread included.
Second Edit: Server Monitor.app still works after disabling hwmond via the plist even after a reboot.
Third Edit: Sorry, keep remembering things, a modified /usr/sbin/hwmond was included the 10.6.8 Server Combo Update package, but not the Delta. Not sure if this matters. How has everyone updated to 10.6.8 so far? Like I mentioned, I used the Combo.

[Solved] Compiz eats up ~20% CPU load in idle after recent update

Today I noticed that Compiz eats up 10-30% of CPU load resulting in the CPU clock often go up to maximum. It might be related with the recent updates but it's not sure - maybe the problem appeared earlier and I just didn't notice it. Restarting Compiz doesn't help, restarting the whole system neither.

OSX Lion QuickTime Internet Plug-In causes high CPU load

I have OSX Lion installed.
Now I have a CPU load between 80 to 130% caused by the Quicktime internet plug-in if I watch my ip-camera with Safari. Also I get no Audio out of my ip-camera anymore. In SnowLeopard everything was fine, Safari CPU load at 30%. What is wrong ? Can anybody help me ? It is an Y-Cam Knight SD and a MacMini core 2 Duo.
Karsten Preussner from GERMANY

I had this same problem and couldn't get it to work at all. I tried to install the 3IVX plugin listed here and it didn't do anything. So I uninstalled it.
Then I thought to try my Macbook Pro and see if it was working on that computer, sure enough it was. I checked the HD/Library/Quicktime folder and it only had 4 items in it, whereas on the Mac Pro (that was not working) had 19 itmes in there. So, I moved all 19 out to a new folder and copied only the ones that were in the MBP. When I opened Safari IT WORKED!!! NO MORE PLUGIN FAILURE.
So, I must have just had too many old things in the quicktime folder that was causing it to fail.
Here is a screenshot of my HD/Library/Quicktime folder contents. The top folder shows the 4 items that should be in there (Perian is optional) and the bottom window in the screenshot shows all the stuff I previously had in there which caused the failure.
So If you are having this plugin failure, try removing all but these essentials from your HD/Library/Quicktime folder. It worked for me!

Start x11vnc -- X uses 100% cpu load

Hi.
I switched to arch64 and today I first used x11vnc and it is extremly slow. First I thought about the proxied connection but after looking into top I found X is using 100% cpu load. With arch32 everything worked as normal. Don't know whats the problem - any advices?
Regard, Andreas

Hmmm, I switched from official nvidia driver to xf86-video-nv and now works much better. I'll try it again with nvidia but not today...

Does the iphone cpu frequency change when the cpu load is different?

Does the iphone cpu frequency change when the cpu load is different, or it does not change, stay a fixed frequency? if it changes, how can i get the realtime cpu frequency?if anyone knows,please tell me, thank you so much!!!

As a general, historical statement Tonefox is correct. For certain particular cpus woodmeister is correct. Cpus have historically been single frequency units, though over-clocking has been done for several years. Doing so pushes the cpu beyond its guaranteed speed, but has tended to work since most cpus from quality vendors will actually operate at higher speeds. The manufacturer just does not guarantee the results...remember the Pentium fiasco in the early years of that chip? Today manufacturers are ceertifying particular product lines for over-clocking on a periodic basis. And that is what dynamic clocking really is, over-clocking but not at a constant clock speed as has been done in the past.
Much of the silicon on the market will function at higher clock rates, the only question is does the maker guarantee the accuracy and performance at those clock rates.

CPU Load not balanced
