BookmarkDav Client spikes my cpu usage when I start up my computer

Has anyone noticed that the BookmarkDav client spikes the CPU usage when it first starts up? Is this something that can be fixed or is there a problem? Thanks for the help.

It has to startup just like everything else in the system, so it's probably normal

Upgrade to iTunes to 10.4.0.80 caused 100% CPU usage when I start iTunes. Task manager shows iTunes 50% mobile 50%. I am running Windows XP Professional sp3. iPhone 3 ios 4.3.5

I upgrade to iTunes 10.4.0.80. Since then iTunes uses 50% of the CPU and Mobile uses 50% CPU. I let it run for hours and the CPU usage stayed at 100%. The phone will partially sync but takes a very long time. This was not a problem before the iTunes upgrade. I am running iTunes on Windows XP professional SP3. It does not matter if the phone is connected to the USB port of the PC. When iTunes starts it runs the CPU at 100%.

Yes! I am not the only one with this problem. Ever since the latest iTunes update, the CPU runs up to 100% using both the mobiledevice and itunes itself. The store won't work either! I'm also on Windows XP. I too have tried everything I can think of but nothing has helped. I really hope they get an update out with fixes soon. This is really annoying!!

High CPU usage when graphics card is put at work

I have a 13inch Air with 2GB RAM and 256GB with Windows 7 Ultimate 64bit. All possible updates have been installed.
I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
Has anyone experienced the same or know what could be causing the beavior?
Many thanks

Maybe my initial post was not clear so let me add some clarifications.
I have the problem with Aero disabled
I have the problem on the Apple site which does not have any flash content.
I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
It would be great if someone you also do the test to check the cpu load:
- when playing a 720 mkv
- when dragging a window across the screen
Just open task manager and see if the CPU spikes.
Many thanks!

High CPU usage when downloading from ITunes Match

When attempting to download matched songs from ITunes Match, ITunes utilization spikes to over 70% and makes it almost impossible to do any other function on the computer. Eventually ITunes fails to respond. I have tried several remedies including reseting winsock. Is there any other options I should try?

Hiya,
could it have something to do with the write speed/ cache/ram? On a "slow" disk, or one that is nearly full or one that is partitioned, it will take a great deal more ram and cache to "digest" the faster download and write it onto disk. I tend to do downloads to a separate drive. Have you got one? and can you repeat the high CPU usage when downloading / saving to the external drive? I note your drive might have 5,400 rpm, with "just" 8mB cache and 320 GB (quite a few SATA's have 7,200 rpm and 32 mB cache).
NB: If anything, I found SL more efficient, especially on my 4 year old Macbook, which is running much faster and has got more responsive after installation of (full version of) SL.

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks

Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Hello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look.

Reduce CPU Usage when Runnig Telnet on Win2000

Does any one knows how to reduce CPU usage when iam running my telnet developed using java classes.Every time when i start Telnet CPU usage is shooting to 100%.Can any one help to me solve my problem.

You are probably doing some kind of loop that is eating all the CPU idle time. You could reduce your use of the CPU by calling Thread.yield() when you do not need to do anything for a bit, or even better, Thread.sleep(...) to pause your program for a specified number of milliseconds.
Hope this helps some.

High CPU usage when downloading Files

Hi there,
i noticed somethign strage when I download file off the internet or intranet. As soon as my download speed surpasses 1MB/s the CPU usage increases. To be exact the process kernel_task.
For example:
2,5 MB/s -> ~30%
10 MB/s -> ~60-70%
10+ MB/s -> ~80%
This is really annoying and I have now clue how to fix this. The Harddrive is a SAMSUNG HM320JI with a Journaled HFS+ partition. No Virus Scanner or anything. Also just reinstalled Snow Leopard yesterday.
Hope someone can give me some useful information how to fix this.

High cpu usage when moving application windows

Hello all,
I have two machines with arch installed:
- an eeepc 701 surf/intel gpu(xorg driver) with xfce
- an amd 3800+ X2/nvidia 8860 gt(proprietary driver) with kdemod3(also checked with xfce4)/arch amd64 installed.
I noticed that when i move a window of an application(for example konsole, etc..) too fast i get high cpu usage(30-40 %), when checking with htop.
Is it normal that the X server uses the cpu so much when moving a window??
EDIT: up to now i tested it in a friends windows machine, and it happens exactly the same, so i guess is normal. It seems i need to be informed better about how X works :-)

today i switced back my desktop system to debian unstable and tried to see what the difference is concerning this problem.
I found out that in kde3 the solution to the "problem" is debians kde default configuration about window behaviour.
Especially the one mentioned below :
In debian this is not ticked and this has as a result zero cpu usage when windows are moved.

ITunes 10.6 has High CPU Usage when switched to Mini Player

iTunes has high CPU usage when switched to mini player. The CPU usage goes to 80-100% when the next song is played in Mini Player. iTunes then stays at high CPU usage.
Upon exiting mini player the CPU usage will drop back to the normal 0-5% levels.
This only happens when playing from the main music library; which my library is at 7089 items, 42.04 GB.
When playing from a smaller playlist such as a smart playlist with about 15 songs in it for example, the CPU usage stays low/normal.

Do you have any better luck with that if you update to iTunes 10.6.1.7?
From the notes for the release:
iTunes 10.6.1 provides a number of improvements, including:
• Fixes several issues that may cause iTunes to unexpectedly quit while playing videos, changing artwork size in Grid view and syncing photos to devices.
• Addresses an issue where some iTunes interface elements are incorrectly described by VoiceOver and WindowEyes.
• Fixes a problem where iTunes may become unresponsive while syncing iPod nano or iPod shuffle.
• Resolves an ordering problem while browsing TV episodes in your iTunes library on Apple TV.

Low cpu usage when exporting

Is it normal to have only 4-12% of cpu usage when exporting video out of ae? I´m exporting it from render queue.
My computer is 2x dual 3,0 ghz prosessor, 8 gb ram, nvidia 8600 gt in xp professional x64
thanks

As Jonas suggested, CPU utilization may be somewhat low because the bottleneck isn't the processing of the data but moving (reading and writing) it.
I'm not saying that this is necessarily what's going on for you, but it's worth pointing out that the CPU is often not the bottleneck.
If disk I/O is what's slowing you down, one way that you can speed things up is to use three disks for your work: one to run the program from, one to store input assets, and one to write output files to.
There are a lot of tips for improving performance in the
"Improve performance" section of After Effects CS3 Help on the Web.

High cpu usage when the system is idle

I do have a high cpu usage problem when the system is idle. I bought the laptop (lenovo x230 tablet) with windows 7 installed in it. Then upgraded to windows 8. But ever since I have problems with high cpu usage by the system even when the computer is idle.
Only the system by itself uses around 30% of the cpu all the time. I ran xperf, and here is the result of it:

I appreciate any help you can provide.
Thanks,

Hi,
I'm sorry for that the log you provide can't be opened on my computer. While according to your description, it should had a special process that consume CPU usage when system idle Iguess, isn't it?
You can use
Process Explorer to monitor the process activity, may be we can find the reason of this problem.
Note: We can use Process Explorer to check the Stack of every process then analyize the problem in deep.
To gave a better insight about this problem, you can take a ScreenShot for this problem and provide the picture here.

High CPU usage when importing CDs. HELP.

Help me! Whenever I try to import CD's or music on to itunes, it automatically spikes my CPU usage to 90-100% and usually stays there, hogging all the activity on my system and making my system run incredibly slow. It also slows down my importing speed to sometimes 0.9x. Which is incredibly frustrating. Also, it is really starting to worry me because sometimes my computer will just shut down without any warning because it is being overworked. Does anyone else have this problem or have any clue what to do? I am afraid it may eventually cause my entire system to crash or something terrible like that. HELP ME!!!

High CPU use should not shut down the system. Yes it produces more heat but if your system has proper cooling then it shouldn't matter.
Look aroung about slow importing. There has been many threasds on this issue here. One workaround is to not watch the progress if the importing, i.e. change iTunes focus to library or store. This has helped many people.

High CPU usage when editing large MXML files

I am using Flash Builder 4.5 Plug-in on OSX. When I have a large MXML file open, Eclipse will consume 100% of the CPU as long as that file is open, even if I am not doing anything. If I close that editor the CPU usage goes back down. I've seen this in Flash Builder standalone as well as the plugin. Is there a workaround to stop this CPU usage problem?
Thanks

hello i have a problem when i start woorksheet, my computer crash with blue screen.
OS: Win 2000 pack 2 and dasylab 7.00.05 ;ddi7.02 ;nidaq 7.0
I hve this problem sometimes and need to reebot my computer.This worksheet is used to generate 4 signals to output and have an acquisition tooin this 4 channels.
The error is in the blue screen:0x00000076 (0x00000000 , 0x81358300, 0x000001c2, 0x00000000).
Thanks for your help.

The DASYLab development team has read your message, and advises that there is insufficient information to be able to even start diagnosing the problem. We suggest that you send a note directly to [email protected], with your full contact information, DASYLab serial number, and the following technical information:
-The Help-->Report information - this will tell us more about the computer, video and installed memory
-Installed hardware - what DAQ devices are you using (exact models!)
-The worksheet that crashes - we need to see how the timing is configured in the worksheet
-What other programs are running at the same time?
-Does the worksheet crash every time?
-Does the NI-DAQ Test Panel work correctly for both inputs and outputs?
Sorry that we cannot be more help in this forum; we do not have much experience with blue screen under Windows 2000. This is very hard to do, and is almost always related to a hardware problem - either a resource conflict, or problems with one of the installed hardware devices (DAQ, Video, Memory...).
