[SOLVED] External USB mouse causes very high CPU load

Hello,
this is far from a scientific test, but if I launch a cpu load monitor and wiggle the mouse cursor over it with the built-in touchpad, the CPU load goes up by 3-4%. When I do the same with a USB mouse, it's 30-40%. Also, in a 3D game, moving the camera around with the touchpad drops the FPS from 35 to 25, while doing the same with the USB mouse drops it to about 5-10 FPS, so something is definetely wrong here.
If I don't touch the mouse, it doesn't produce any load.
The CPU load comes from both X and the window over which I am wiggling the cursor, whether it is a terminal, browser or whatever, with the window contributing about 2/3 of it. If I don't do it over a window, the excessive load comes only from X and is much smaller (but still several times bigger than the load the touchpad produces).
I have no idea how to even tackle the issue.
I run Arch 64, on an Asus 1201N laptop. The mouse is Logitech G5 (laser mouse).

Have you tried with a different mouse, to check if it is specific to this mouse /driver? Does lowering the polling rate help? (https://wiki.archlinux.org/index.php/Mouse_Polling_Rate) .I remember vaguely that laptop mode caused this too.. search the forums for mouse and cpu.

Flash causes very high CPU load (including high Xorg load)

Hello everybody,
this is my first message. I'm an Arch user since a few months, and I'm pretty sure this is the distribution I'll stick to - I pratically love everything about it, especially its simpleness. It's the first Linux that doesn't scare me away with tons of configuration files scattered around dozens of different locations. I've already gotten quite a number of things fixed by myself without even looking at the forum or wiki.
Well, it seems most of these statements can be found in most first forum posts, so I'll stop to bore you...
The problem: Playing flash videos or animations causes incredible processor load: Even youtube takes a whole CPU core (or even a little more), top shows around 80% for Xorg and around 20-30% for Firefox (a little less with Opera). I'm on Arch64 with XFCE, Athlon X2 4600+, NVidia 8200 chipset (which has severe driver problems anyway; I'm using the latest NVidia beta driver). I'd try the open source nvidia driver, but (it seems that) there's no support for my chipset yet.
Currently I'm using Adobe's Flash64 alpha, before that I used various versions fo the nspluginwrapper. 32-bit Flash also caused high CPU load, but it wasn't that much and it may have been related to nspluginwrapper rather than anything else; however I have got the impression that things became even worse with the switch to the x64 alpha (performance-wise; on the other hand, it at least loads faster and doesn't crash anymore). Like said before, youtube takes one core, but it mostly works ok then, but videos with higher resolutions that youtube's are practically impossible to watch (except when there is very little movement in the film). Neither Flash hardware acceleration on nor off makes any difference.
I've already read half of the web, searched in forums, wikis, etc., but didn't find anybody with the same problem. When Flash64 was released and people were reporting good improvements, I was hoping it would be the same for me...
What I'm looking for is suggestions of things to try... I'm out of ideas what to try and where to look. It just seems strange that I seem to have problems that others don't...
Thanks for reading and for any comments.

Hehe, I'm also wondering how many Cerbies are out there...
Really funny. The internet is a small place, obviously. Us meeting in a Linux forum also explains why nobody writes to the LSML anymore.

Which will cause a higher cpu load, the sampler instrument or the original audio tracks?

I have some piano that I wanted to loop. I had no problem using the convert track to sampler instrument. My question is about CPU performance. Which will cause a higher cpu load, the sampler instrument or the original audio tracks?

Hi Mesaboogiewes,
Welcome to Apple Discussions
Ableton.com recommends disabling Energy Saver, fullscreen mode, and Exposé. I would recommend putting the 1Gb of RAM, you will find a better result. I suggest going to the Ableton.com website and looking for more troubleshooting issues.
I hope that helps,
Jon

[SOLVED] External USB mouse doesn't work

I've installed Arch on my laptop and today faced with a problem. When I boot with AC off my external USB mouse doesn't work. Also it looks like USB ports don't work. If I detached AC when working mouse works fine.
I can suppose there is some problem with laptop mode. May be it turns off usb ports to save energy. Anyway quick search doesn't brings any results. If someone give me a hint how to solve this problem I'll be very grateful.

Well, after diving into configs solution has been founded. The point was to disable auto suspend feature in laptop-mode-tools config by setting BATT_SUSPEND_USB variable to 0 in /etc/laptop-mode/conf.d/usb-autosuspend.conf
Hope this information will be helpful for users who probably faced with the same problem. Thank you!

XML select query causing very high CPU usage.

How can i generate execution plan?

How can i tune this query?
How can i find that this is the only query causing High CPU usage?

Xorg causes extrem high cpu load

Hello,
from time to time xorg causes a extrem high cpu load on my system.
http://imageshack.us/f/38/xorgload.png
After a reboot it should looks like that
http://imageshack.us/f/16/xorgnormal.png/
Is there any possibility the figure out why this happens sometimes?
Thanks for your help!

Hehe, I'm also wondering how many Cerbies are out there...
Really funny. The internet is a small place, obviously. Us meeting in a Linux forum also explains why nobody writes to the LSML anymore.

[SOLVED] Audio playing bad except with high CPU load

I recently switched to a new motherboard: Asus Z97-Deluxe
This motherboard has a ALC1150 audio chip, which uses the snd_hda_intel driver.
CPU: Intel i5-4670K
Kernel: 3.14.4-1-ARCH #1
alsa-info: https://drive.google.com/file/d/0Bymxsc … sp=sharing
Audio is playing bad: 'radio noise', skipping, repeating. It is unusable.
Before I used pulseaudio, but to diagnose this problem I have removed it.
Now with alsa left, it plays a little bit better, but the problem is still there.
The only moment when the audio works great is when the CPU is busy, such as compiling a Linux kernel.
Sometimes moving the mouse has a positive impact too.
My gut feeling tells me the cause might be the BIOS, the driver, power management or CPU scheduler.
Since I have been searching for about a day on the Internet and trying most of the offered obvious solutions, I am now searching for active help.
Any suggestions how to approach this audio issue?

The option "options snd-hda-intel enable_msi=0" does not seem to have any effect.
For each change in alsa-base.conf, I have rebooted the machine.
There are no other sound cards in the system.

High CPU load after firefox 18.0 update, causing periodical hang

Hi, I am basically getting crazy here after the update to firefox 18.0 yesterday.
Firefox periodically causes very high CPU load, which makes it impossible to use.
http://img805.imageshack.us/img805/702/firefox18.png
The problem does not occur immediately after restart, but you can already see the spikes of CPU load in the taskmanager with a peak of ~4%. After a couple of minutes this will go up to almost 50% utilizing a whole core and causing the hangs.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

VI causes high CPU load after several days of running

Hello,
I have a strange problem. I have craeted a test bench control VI and it runs on five PCs, controling five test benches. All PCs have almost the same hardware, same motherboard, same CPU, etc.
Normaly the CPU load is around 50% when I run the VI, but at one PC the CPU load climbs up to 85% after several days (maybe one week) of continuous running and the PC is almost tied up - the VI execution becomes very slow (10 times slower) and the mouse only moves very slowly.
First I thought that the PC has a problem but the problem dissapears as soon as I stop and restart the VI!
I don't even have to terminate LabVIEW - only my VI and then everything is okay again.
The problem does not seem to occur at the other four PCs, but I can not tell for sure.
The task manager says only LabVIEW causes the CPU load - swap file utilisation is little.
Is there a way to analyze what causes the high CPU load?
I Use LabVIEW 7.1 professional
Operating System: Win XP (SP 2 or 3 I don't remember)
P.S. I have no loops without wait-functions.
Greetings Johannes
Using LabVIEW 7.1 and 2009 recently
Solved!
Go to Solution.

Do all PCs have the same amount of RAM?
What is the memory use over time as seen by the windows taks manager. Does it increase gradually?
An increase in resource usage if often cause by sloppy programming.
Do you grow arrays forever or constantly resize arrays in memory? (built array, insert into array, delete from array)
Do you often create new references and never close them?
What does the program actually do? In my opinion, a constant 50% CPU load seems too high for my taste. It means it would not even be able to keep up on slightly older hardware.

High CPU load and com.apple.ImageCaptureExtension2 crash after upgrade

After upgrading my Macbook Air from Lion to Mountain Lion, the system has a very high cpu load, and the crash reporter is the process that causes thee high load. In the error log I see this entry several times per second:
17.08.12 12:58:46,011 ReportCrash[5998]: com.apple.message.domain: com.apple.crashreporter.writereport.crash
com.apple.message.signature: Image Capture Extension
com.apple.message.signature2: com.apple.ImageCaptureExtension2 ||| 8.0 (8.0)
com.apple.message.signature3: 03A96CBDA3C85A114383537BFC5C8999
com.apple.message.result: NO
com.apple.message.summarize: YES
I investigated a bit more and recovered, that it has something to do with the printer drivers. When I remove all printers from setting, everything is fine. As soon as I add a printer (Brother MFC 9440CN printer/scanner, printer driver provided by Mountan Lion), the crash reporter starts it's work and the error log is full of those entries.
Any suggestions?
Thanks in advance,
Marcus

I did more exploration and found the cause of this, but I don't know how to fix it:
I removed all Brother and Lexmark printer drivers and rebooted (and also tested with a virtual machine using 10.8.0 as guest os that never had any printer installed). As soon as I enter the printer settings and press the "+", the crashes begin, so it looked like the bonjour one of the printers announcing themselves via Bonjour were causing this.
When watching a picture in the preview app the same happend. We have two multi function printers in our network, the already mentioned brother printer and a Lexmark X204N. Switching off the Lexmark (which wasn't installed on my Mac) solved the problem. Switching off the printer is no solution in our office (it's our fax device and main printer), but switching off mDNS on the Lexmark also solved it. But this can only be a workaround.
Is this a known problem with Lexmark devices and Mountain Lion (it works fine with machines using Lion)? Are there any fixes known? It's just the Lexmark device announing itself via Bonjour that causes trouble, even if the driver is not installed.

Permanent high CPU load and timeouts in communication channels

Dear Colleagues,
we've a strange issue since last week. At first we had an problem with a redirect to the cytrix online booking engine within the travel management application of our SAP NW Portal. There is a redirect.jsp file deployed in our PI system that connects to cytrix and passes the URL with session link and session cookie to our Portal. We fixed that issue by restarting the PI system.
We have a PI 7.0 stack 23 on HP-UX.
After restarting we found that we've got a very high CPU load (about 75% overall CPU, or 300% at 4 CPUs) probably caused by very frequent (3 per second) minor garbage collection runs (as seen in GC.log).
On friday we had timeouts within one of our communication channels in the PI system.
We changed the heap size from 2GB to 3GB and the new generation from 341MB to 768MB and restarted the PI system. But after a few ours the system uses 75% RAM of the CPU high CPU load and the GC runs are still the same.
This is a short excerpt of our GC.log:

Does anyone know what can cause the high load?
Is the frequency of the GC runs normal?
Can the timeouts be connected to the high CPU load?
The error ony occurs on our productive system.
I'd appriciate your help very much.
Kind regards,
Paul

hi Paul,
I believe an issue like that needs to be done onsite and not via a forum
as it probably requires doing lots of checks/tests
my suggestion would be to get a PI consultant expert with basis experience onsite or do it via OSS with SAP

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.

Sm3K3R
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...

Too high cpu load with HP 6510b

Hello guys,
I have a very high cpu load on my laptop even if nothing despite htop is running. I guess it's a problem with acpi because when I deactivate acpi completely over the bootline I have no such problems.
How could I fix that?
Thank you in advance.

Hello B,
unluckily noacpi doesn't help but acpi=off. That seems to be the only way to stop the high load.
Is there any patched acpi or something else?
I also think I picked the bad revision with fan problems and some more...

High CPU load

We use vSphere 5.5 with latest updates, Web Client and the VMware Remote Console 7.0.1. But we have problems on our Citrix Terminalserver (Windows 2012 R2): When we close a Remote Console, the prozess "vmrc.exe" didn´t disappear and causes a high CPU load (one complete core). This happens when we use the IE, Chrome or Firefox.
I don´t know why this happens, have anyone an idea? Thank you!

One thing to check is that there isn't some other process running in the background which is also using a lot of the CPU. Open Activity Monitor and select "All Processes" at the top and "CPU" on the bottom bar. If you find some process other than the BOINC that is using a lot of the CPU, highlight it and quit it and see if this helps.
If you haven't already, install iStatPro from the Apple site and keep an eye on your computer temperatures and on your fans. As long as your fans are working properly, they should keep your processor cool enough to not overheat.
It might also be worth investing in a chill mat, just to help keep your Mac cool overnight.
Good luck!

Having touchpad auto disable when external usb mouse is present

Apparently as hardware and drivers change this feature got dropped. Just purchased a Probook 450 and was very used to my touchpad having the option to turn off when a external usb mouse (logitech wireless) was plugged in. This new system had no such feature and I spent several hours searching for a solution of reason why.
Finally found one I took a shot on that worked just like I was used too. Now when usb mouse is inserted the pc pops up message saying touchpad disabled and when unplugged the touchpad comes back on and pc pops up message saying pad enabled. No software change. No hardware change. Just a simple registry edit and feature back on.
Seems after doing my searches I might as well share this info for those looking for the answer.
***disclaimers***
*make sure your usb mouse works before you do this because if it dose not and this fails to work or you do it wrong you may have no "mouse" to navigate with.
*warning- editing the windows registry is not something for the clueless*- errors can cause major problems that said this is a very simple simple fix and hp should just perma fix it for all synaptics touchpad laptops.
*can not test this with non synaptics touchpads tho it may work if you can find the registry entry for that brand*
*this was done on windows 7 system with Synaptics touch pad and my prior one was windows 7 and so was my wifes dell laptop, all Synaptics, all Windows 7- no clue on windows 8 or vista*
*if someone has found an easier fix post it because took me hours to even find this*
Windows 7 OS- Start menu- in the programs and files box at bottom type "regedit" without the quotes and press enter.
Click ok to continue on popup box. Window comes up with your system registry. Expand the "HKEY_CURRENT_USER" then expand the "Software" then down to the "Synaptics" and expand that one. Left Click on the "SynTPEnh" and to right will open the sub entries. The one your looking for is "DisableIntPDFeature". Just write down the last two numbers in the ( ) at far right of this line incase this does not work so you can put it back to what it was. Once you wrote it down, now you can change it- right click on the DisableIntPDFeature and a window pops up. Left click on "Modify..." then in new popup window on right side left click on decimal and in the window on left of this popup type in the numbers 51. Left click OK once numbers entered and close it and and then close the whole application and reboot. Done. System should auto switch from usb mouse to Synaptics touchpad.
If it does not work I am sorry- follow the above steps and type back in the number you wrote down before the change and save and reboot or reinstall the mousepad driver for your system from hp.
