100% CPU usage when importing cd and downloading from store, please help!

I am using itunes 8.2.1.6. The problem is that whenever I import a cd or download any music from the store my cpu runs at 100%. I have a pentium 4 (which manages nicely with any other task, even importing cd's with another programe) with 3gb RAM.
Is anybody else having this problem? Does anybody know how to fix it?

Server 2012 R2 100% cpu usage when using search

Hi all!
We are experiencing issues with the built in search in WS 2012R2 (Win+Q). Upon starting to type, the explorer.exe process peaks and stays at 100% until typing is done and the search is complete. It also can't keep up with typing and hangs after
a few keystrokes. We have done tests on 2012 R2, 2012 and 2008 R2 running as VMs with 1 cpu. The tests performed have been run on a host running only the test VM with underlying 2x8 core cpus, SSD, SAN storage and 256GB RAM. Also, we have tested
both Hyper-V and VMware ESXi 5.0. We see that if we add another CPU to the guest it alleviates the keystroke lagging, but the explorer.exe still consumes 100% cpu.
When the same tests are run on a physical machine (approx. same specs as the virtualization hosts) the cpu usage reaches 15-20% on one of the physical sockets (numa node). Totally negligible, but still a high number.
We are afraid of service impact and are keen to know if anyone else is experiencing the same? Maybe someone has a fix?

Hi TrondWH,
Thanks for contacting Microsoft.
Currently, would you please try cleaning boot the server and test how the issue goes. Cleaning boot can exclude some third-party application affect. Following are the detailed steps about clean boot:
Log on to the computer by using an account that has administrator rights.
Click Start, type msconfig.exe in the Start Search box, and then press ENTER to start the
System Configuration Utility.
On the General tab, click Selective Startup, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
Click OK, Choose Don’t show this message again and then click Restart.
Please check if the issue is still the same.
Please let me know the result.
Best regards,
Sophia Sun

Bug!?! 100% CPU usage when referencing secured JARs in unsecured JNLP

hi,
i think i just found a bug in jws but i'm not sure yet. it would be nice if somebody can verify this before i create a bug report.
this is my JNLP file (test.jnlp):
<jnlp ...>
<information>
    <title>Test</title>
    <shortcut online="true">
      <desktop/>
    </shortcut>
</information>
<security>
    <all-permissions/>
</security>
<update check="always" policy="always"/>
<resources>
    <java version="1.6"/>
    <jar href="jar/mySecuredJar.jar" download="eager" main="true"/>
</resources>
<application-desc main-class="test.MyTest"/>
</jnlp>this is the file structure on the server:
download/      // public folder
   test.jnlp
   jar/        // private folder secured via basic authentication
      mySecuredJar.jarwhen i access the jnlp file for the first time via browser the jws login dialog opens asking me for credentials since test.jnlp internally references a jar that is in a secured area. while this jws dialog is open my cpu usage is normal - javaw.exe takes about 5%.
however, when i open my application for the 2nd time via desktop shortcut, the jws authentication dialog opens again (jws looks for updates of my jar before the application starts) and javaw.exe takes about 95% of my cpu as long as the dialog is open!!!
when i put the jnlp file in the secured area as well, everything works smoothly. however, this forces users to enter credentials in a browser authentication dialog (browser needs to access the secured jnlp) as well as in the above mentioned jws authentication dialog.
can anybody reproduce this? should i file a bug report?
i tested this on win xp with jre 1.6.0_11.
regards,
stephan

100% CPU usage when writing to disk

Hi.
I have an Athlon XP 2000+ with 768 MB RAM, a SATA disk, formated to ntfs (running XP) and a IDE disk running Arch (ext3, KDE).
When I copy a big file, the CPU usage stucks to 100% . Doesn't matter the disk I write to or from. The CPU usage is always 100%.
My maximum writing speeds are:
ntfs-3g-->ext3 max ~30 MB/sec
ext3-->ext3 max ~28 MB/sec
ext3-->ntfs-3g max ~15MB/sec
ntfs-3g-->ntfs-3g max ~15 MB/sec
I understand that writing to ext3 is much faster because it is a native linux fs, but I cant understand why the high CPU usage.
While coping, ksysguard shows that the progress with the higher system% is kio_file when coping ext3-->ext3, or kio_file and ntfs-3g, when coping from or to a ntfs disk.
The problem is not with the CPU, in windows the writing speed is higher and the CPU usage is much lower. So I thing this is an Arch configuration problem but don't know where exactly to look. Searched the forum but didnt find any solution.
Any ideas? Anyone with similar problems?

It says ATA device, with non-removable media but this is a SATA disk!
Also,
# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 166 MB in 3.01 seconds = 55.23 MB/sec (SATA Disk)
and
# hdparm -t /dev/hdb
/dev/hdb:
Timing buffered disk reads: 176 MB in 3.02 seconds = 58.26 MB/sec (IDE Disk)
hdprm says dma is on for the ide disk, but says nothing about dma for the SATA.
I think the problem is because the kernel recognize the SATA disk as IDE.

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 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.

I have very high 100% CPU usage when I run itunes.

Normally I don't have any problems, but now when I start iTunes it eats up my CPUs. Any thoughts?

I am having this same problem. When running iTunes on my macbook pro, i notice my CPU usage is hovering around 94-97% constantly. Has anyone found out why?

HT3702 My bestfriend signed in to my iTunes and her account owes money and i tried o log back into mine on setting and her account still seems to appear when I'm trying to update and download an app please help. We have tried everything.

My bestfriend signed in my phone as her iTunes which she owes money to i tried logging back into mine and it won't let i tried setting and iTunes logout logged in as me and it say it but when i go to update and download a app its still showing up her username and stuff so i can't do anything .

What id shows at the bottom of the Featured tab in the App Store app ? You could try tapping on the id there and logging out of it and then log back in with your account - if your friend downloaded any apps then those apps will be tied to her account, so only her account will be able to download updates to her apps.

I am getting no sound from my iPod, although it works when on dock and with headphones. Please help

I am getting no sound from iPod, although works when on dock and when headphones are in. Please help

Does Ford say it will work with the 4G iPod?
Contact them.
Sometimes this works:
- Reset the car system
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
It just may not be compatible.

100% CPU Usage, Sound configuration Error and Unknown Error (0xE8000001)

Hi, I just bought a iPod Touch - amazing iPod I must say.
Pluged it in to my Windows Xp to sync some music. (I've been using iTunes for several years now and just upgraded from a 1st generation iPod nano to a 16 Gb touch).
It connected very well and I was ready to sync but then I made a stupid mistake - I updated iTunes to be sure that every thing was up to date.
After the update I get an error about my sound configuration (I've tried uninstalling QuickTime and installing again - didn't work). iTunes open up and starts to sync and now a second issue apears. It uses all of my CPU - flatlinig at 100%, so I cannot use my computer at all. It is now syncing but extremely slow - one song takes about a minute. Now the iPod touch starts to say these weird sounds and rebooting every 20 seconds or so. Finally I get an eroor in iTunes saying that there has been an unknown error (0xE8000001).
So I'm stuck with iTunes not working and no songs on my iPod.. :o(
What to do..?

Lion, external monitor, and wake from sleep - please help!

For the most part I love Lion. However, the changes they made to the external monitor support are not helpful for me. Let me explain...
I have a 13" 2009 MBP. In my office I use a monitor stand that the laptop can slide into from either the left or the right, and the monitor sits on top. Previously I would simply take my closed MBP in sleep mode, slide it under the stand, and plug everything in. Once the power cord and monitor cable were plugged in, as soon as I inserted something into the USB or SD-Card slot (or I think even the ethernet jack) the laptop would wake from sleep and the monitor would come on.
Now, however, this doesn't happen. My only option is to plug everything in, open the laptop so it wakes up, then close the lid, then slide it into the stand. This is definitely NOT an improvement! Before I had my phone at the left of the monitor stand, and would slide the laptop in from the right. Now, though, I have no choice but to slide it in from the left (after going through the above hassel), which means I had to move the phone off of my desk.
The energy saving preferences have the "wake on network access" box checked, which would make me think that it would wake up as soon as the ethernet cord is plugged in - but no such luck. I also have wireless in the office, but it's hard for it to recognize that when it's in sleep mode.
Has anyone else had this problem? Is there a solution I'm missing here? I'm using a wireless keyboard and wireless mouse, so of course those won't do anything while the computer is asleep.

I'm beginning to hate Lion because of this one problem. It's great that Lion doesn't sleep when you close the laptop with external monitor connected. But I can no longer wake the external monitor with USB mouse movement. I have to open and close the lid. This is very inconvenient when switching between two systems with KVM. The MacBook is awake; it just won't wake the monitor.

100% CPU usage with XP Cooler from PCAlert4

Any idea why I would be running 100% cpu usage when running XP Cooler from PCAlert4? I noticed PC was sluggish when running it so CTRL+ALT+DEL and under performance is 100% CPU with 245MB Ram Usage. No other TSR's running - several application but under 10% CPU usage without PCAlert and XP Cooler.
I was also wondering if anyone had any ideas on the video? I have the K7N2G with 768MB DDR PC 2100 (3x256) XP2200+ 266FSB running 1804MHz - Maxtor 30GB 7200RPM - 350W PSU (raidmax - yea yea I know, dont say a word though LOL) on board video and here is the problem - graphics are great, but they get choppy - running NFS HotPursuit 2 at 32bit 800x600 (doesnt seem to matter even when running 16bit 640x480still does it.) what setting am I missing? Thanks in advance.

Deathstalker (Richard),
I did what you suggest in memory management and also changed out the mem on the board - it did make a difference, not as much as I had hoped, but it did.
Raven,
I have used Fraps in the past, forgot about it, but went ahead and downloaded it to get a better look.
To the Both of you,
Thanks so much for your replies, sometimes it just takes someone outside looking in to see the things overlooked. But I went ahead and also ran all of the latest updates for the board (semi new system and I only installed with the CD that came with the Mobo) and everything is running better than expected. Thanks again for your thoughts - keep 'em flowin, it's amazing whom we could help. Take care.

100% CPU Usage caused by HMI

Hi everybody:
I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
Thanks in advance!

100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
CPU Usage 100% Symptoms
When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
CPU Usage 100% Cause
These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.
