[Desktop][OS X] CPU Use 90%

Thread: 443498
Status: New
Description:
After updating to Spotify version 0.9.2.18 CPU usage goes up to 90% and more on OS X
Additional information:
This seems to be limited to the latest Spotify version (0.9.2.18), on OS X
Please provide this information so we can investigate:

OS X version
CPU Usage before and after launching Spotify

I'd like to offer a solution that worked for me instantly. High CPU usage has been an ongoing problem for me with Spotify. CPU usage was consistently at 80-120%. I have a very large music library on my computer and I wondered if that might have something to do with the problem. I went into preferences and unchecked all local music sources as shown here:
Once I unchecked these, my CPU usage immediately went down to about 5%. Apparently the app was slogging though indexing and listing all of these songs. I tried re-checking the boxes, and as soon as I did the CPU immediately shot up to 80%+ again. When this scanning/indexing is happening, you will see this animated blue circular arrow indicator next to "Local Files" in the left menu.
I tested by checking only iTunes in the preferences and I let it keep running and when the blue animation stopped, the CPU went back down to 5% again. I restarted Spotify to see if the scan would last and it did, CPU was still at 5%. Then I checked "Music" and the scan started back up and CPU shot up again.
I wondered if I made changes to my iTunes library if the scan would start over, so I quit spotify, started iTunes, made a few changes and created a new playlist and quit iTunes. I reopened Spotify and the scan only took a few seconds and CPU was normal again.
I hope this info is helpful for Spotify to do something to manage this scanning for large libraries, because it really renders the computer unusable until the scan is completed.
Version Info
Spotify 0.9.1.57.ge7405149

[SOLVED] [KDE4.1] Mucho cpu use with desktop effects enabled

With KDE4.1rc1+ desktop effects enabled, I'm consistently getting figures of 40-60 percent CPU usage, even when I'm not moving anything around the desktop.
With desktop effects disabled, CPU use is negligible.
This is on a Thinkpad T61p with a T9300 2.5GHz C2D processor, 4Gb RAM, nvidia Quadro FX 570M graphics, running Arch64.
Is this normal?

Following a suggestion by Pierre, I disabled vsync, which helped dramatically. CPU usage -- with desktop effects enabled -- has dropped from 40-60 percent to < 10 percent, usually around 2-3 percent.
Vsync can be toggled under System Settings / Desktop Effects / General / Advanced Options. I tried all kinds of other xorg.conf tweaks and nvidia-settings options, but this is the one that really helped (the others, I'm not sure about).
Several other users have reported the same thing.
I'm tagging this "solved".

How do I get messages to go back to an AIM account? It's only seeing the iPad's Facetime email address and not seeing the old AIM account name that is on my desktop. I am using my iMac using iChat to talk to a newer iMac that doesn't have iChat.

How do I get messages to go back to an AIM account? It's only seeing the iPad's Facetime email address and not seeing the old AIM account name that is on my desktop. I am using my iMac using iChat to talk to a newer iMac that doesn't have iChat. We had this working using Messages and Facetime (on the new machine) talking to my existing iChat account. One day last week, when Facetime rang, my kids answered on the iPad. Dang! Now it's all fouled up! The new iMac won't see my AIM account name and shows that I'm offline, because the iPad is off. We were able to call using "most recent call" in Facetime, but now I can't go and control that new iMac remotely to help with some email concerns the user is having. I'm trying to not personalize this too much, but it's grandkids talking to Grandma and Mom and Dad trying to solve new machine hiccups. Normally, I could just go in via iChat and control the other machine and troubleshoot, but I can't do it with Facetime only. My buddy list doesn't see the other computer even though we are connected on Facetime right now. My name is not highlighted for the other computer. What could have gone so wrong?
Any help would be appreciated.

How do I transfer the songs from my desktop to my iPad using the same iTunes account? I can only sync the other way. Thanks

DaisyDoodle,
The songs on your Shuffle should still be in your iTunes library. That means you should just be able to connect your Nano to the same iTunes library and sync it just as you would with your Shuffle. There is no limit to the number of iPods, iPads, or iPhones you can sync to one computer, iTunes library, or account.
As for preparing the Shuffle for your husband, just restore it via iTunes and then let him sync it to his own iTunes library or if its the same iTunes library, let him configure it to sync only his content.
Here are instructions on how to restore the Shuffle if need be.

HT204053 How to I get music I purchased before the iCloud was created to show up on my new authorized iPhone? Right now I can only see the Apps I recently purchased on the actual phone but older music I purchased on my CPU using the same Apple ID doesn't

How to I get music I purchased before the iCloud was created to show up on my new authorized iPhone? Right now I can only see the Apps I recently purchased on the actual phone but older music I purchased on my CPU using the same Apple ID doesn't appear.

Does any music show in the Purchased tab on the iTunes store app on your phone ? Music can't be re-downloaded in all countries, and even where it can be it will only appear whilst it remains in the store. Do you have your purchases on your computer and/or on a backup of your puchases so that you can sync them to your phone ?

Some web pages causing 100% CPU use of iexplore.exe since Flash update

I'm having a problem with certain Amazon.com pages hanging my
Internet Explorer 6 using Flash Player 10,0,12,36, causing 100% CPU
use for iexplore.exe and requiring me to End Task to quit. All the
pages effected have an interactive mouseover Size and Color chart
that intially says "Loading" but then says "Select Size and Color"
once loaded. One mouseovers the various color patches and size
options, each time giving item availability in that option. When
the pages hang the IE browser with 100% CPU use that chart never
gets to the "Select Size and Color" point, instead stuck at the
"Loading" status. This happens most times, but not every time.
Sometimes the pages load correctly, after a brief lag as it loads
the chart.
Amazon pages without this chart load fine.
The start of this problem coincides with updating Flash.
I can prevent the problem from happening almost every time if
I can quickly get my cursor into that chart area while the page
begins loading. If I allow the pages to load fully with no
interaction they will hang almost every time.
I have not noticed any problems on those same web pages using
Firefox using Flash Player 9,0,124,0
I also have not noticed any issues with other sites using
Internet Explorer either. (YouTube, QVC, CNN...etc, all OK.)
I had posted for assistance on the Experts Exchange site and
there was some debate on whether the chart was a Java or
Flash-based chart, so initially it was being approached as a
possible Java issue, so I removed all Java versions on the system
and installed various versions, but the same problem persists.
I've downloaded but not run the Flash Uninstaller, as I'm
reluctant to uninstall the Firefox Flash version without knowing
for sure I could install 9,0,124,0 again.
I've downloaded an archived fp9_archive.zip, which seems to
indicate the contained files flashplayer9r124_winax.exe (Internet
Explorer) and flashplayer9r124_win.exe (Netscape) would be versions
9,0,124,0 to install after running the uninstaller.
Can anyone check a few of the links below and see if the
"Select Size and Color" chart is Flash based? If so, would
executing the files listed above install 9,0,124,0 into my
respective browsers again?

CPU used by ORACLE

Hi,
on 11G R2, on Win 2008.
In Windows we can not see background process (mmon, pmon, ...). Can we ?
How to see CPU used by Oracle background process ?
To day CPU was used at 90% by oracle.
I ran an AWR. But nothing about them in it. I wonder why Oracle was CPU intensive ?

Hi,
You can go to TASK Manager -> click on Resource Monitor and there can see different services/processes along with the amount of CPU they are consuming.
Hope this helps you.

Why do I have to update the remote desktop if I never use it

I have this update/install now? sitting in my software updates. It's for REMOTE DESKTOP CLIENT UPDATE. I will NEVER use REMOTE DESKTOP CLIENT UPDATE. Why do I have to install it to make it go away?

Apple Remote Desktop (ARD) Client is used for screen sharing.
It is also used by administrators of companies that have the "server" version of Apple Remote Desktop. They use it to remotely maintain and support the OSX computers in their charge. The ARD client can share information to the system administrator about your system to maintain it.
With that said:
If you are using an OSX earlier than Yosemite, you do not want to make the upgrade to ARD client 3.8 (v 1.1) because it breaks screen sharing.
If you have OSX Yosemite, you can go ahead and make the upgrade and you will not notice any change.

CPU used by this session

Try to get CPU usage from within Oracle by monitoring "CPU used by this session" parameter in v$sysstat, but got some values over 100%. Is my calculation wrong or this is the problem of how Oracle collecting the data? Here's my calculation: CPU Usage (percent) = round((end_value - begin_value) / time_in_seconds, 2)

Please don't double post: {thread:id=933247}
Thanks!

CPU used by oracle user

and b.value > 0
order by a.sid, c.name
If you have the licences for the diagnostic pack and performance pack, you can look at the active session history for this type of information. You can query view DBA_HIST_ACTIVE_SESS_HISTORY, or run the ashrpt.sql script from $ORACLE_HOME/rdbms/admin, or use OEM for a graphic representation of the workload over time.

ITunes 11.0.4 - high CPU use

Hello,
since I upgraded to Mountain Lion 10.8.4. and iTunes to 11.0.4 a couple of days ago, iTunes keeps fooling around using up to 130% of my CPU (how is that even possible?!) when playing music. As soon as I pause the music, the CPU-use goes back to >1%. Before the upgrades I had a big library with over 170GB of music (no only a few albums) and no problems using iTunes whatsoever.
I run a mid-2010 13" MBP with OSX 10.8.4, 2,4 GhZ Intel Core 2 Duo and 4GB of RAM.
Thanks in advance!

Yessss! i' ve finally found the issue !
The problem was with "smart play lists" i dunno how you call it in english, but i' ve created a long time ago a smart playlist named "unread" because the "all random" function is not so much random for me, as they play some tracks more often than others...
With as criteria " numbers of play = 0 " so one title is played one time!
By using my brain as good as i can, i told myself " what itunes do when a song ends and then go to the next?"
It wrote something on the smart play list or something like that
Then test from "play all random" = no more issue !
Then deleted my smart play list and recreate one identical = problem solved !
norbml : i hope this help you
