IPhoto uses lots of CPU time while idle

I run iPhoto '08 (7.0.2) on a G4 iMac that I use as a photo and music server. Today I was using the computer to rip some CDs and scan the covers and the computer seemed sluggish. I checked Activity Monitor and saw that iPhoto was using between 20 and 60% of the CPU time even though it was hidden and hadn't been active for at least a day. When I activated iPhoto it went back down to 1% or less. I hid it and it remained at 1% or less for a while, but after about 15 minutes it shot back up to 20-60%. Any ideas as to what might be going on?

I seem to find that both iPhoto and Safari grow in virtual memory used and CPU used as time goes by so I try to restart each of them every couple of days and he whole computer at least once a week (no it shouldn't be necessary -- but at least it is still better than windows)

  • ITunes uses lots of CPU time when idle

    When iTunes is just sitting there with my Music Library displayed, Activity Monitor shows it's using a pretty consistent 22-25% of CPU time. I look at Activity Monitor once in a while and I've never noticed this before. I don't know if it started when I upgraded to iTunes 7.4.2 or not. Other Macs I have access to use close to 0%. I have repaired permissions, checked the hard drive, and waved the other dead chickens over it without any change. Obviously this soaks up a lot of machine resources. Any clues or ideas would be welcome.

    Never mind, I figured it out by myself. On this particular machine I had a 3rd party plug-in installed (SRS iWow 1.1.8). Removing that brought the CPU usage down to 0.1%. Usually I don't install 3rd party add-ons. This would seem to be a good policy.

  • Dock uses lots of CPU time

    I find Dock uses ~140% CPU time sometimes, I can't see a cause for it to do so. It usually stops of its own accord after a random amount of time. Killing it doesn't help, launchd restarts it and it goes back to using lots of CPU.
    I have parallels install and I have the version which has the fix (6.0.12106) and I have also tried the work around (no luck obviously).

  • Thread.sleep takes a lot of CPU time!

    Hi,
    I have the run method like this:
    public void run()
    while(true)
    //some set of operations
    Thread.sleep(5*1000*60);
    The above code's performance was measured under stress test. . The sleep operation seems to take a lot of CPU time
    though ideally sleep is like a no-operation mode, meaning since no operation
    is done when a thread sleeps, it should not use any/minimal CPU time.
    But it seems to take over 30% of CPU time!
    Any ideas on why such a weird thing's happening?
    In fact, in one more similar method also, sleep is taking similar CPU
    time.

    A sleeping thread uses no CPU. Try the following, both with and without the for loop. If you see a constant high CPU usage, even when the thread is sleeping, it's probably that the CPU usage is measured as an average over the last second or several seconds, so when the tasks you're performing are intense and take a significant fraction of the time you're sleeping, the average CPU usage doesn't go down that much.
    public class Sleeper {
        public static void main(String[] args) throws Exception {
            while(true) {
                for (int ix = 0; ix < 100000000; ix++) {
                    int jx = ix * 2;
                    ix = --jx;
                Thread.sleep(5 * 1000* 60);

  • [Solved] embedded videos in firefox take a lot of CPU time

    Playing embeded videos in Firefox take a lot of CPU time. Actually my old computer is not able to play these videos correctly if they are in HD. The problem appears with flash videos (not so surprising, flash sucks...) but also with html5 videos (there is an option in youtube to turn that on). However if I succeed to have the direct URL, these videos play perfecrtlky fine in mplayer using not more than 10-20% of CPU time. Is there a solution to that? Is there any possibility to use an external player to play HTML5 videos in firefox? If anybody knows, Why this problem, are the mozilla folk aware of this problem? (Note that I posted a thread a long time ago for this problem but concerning flash only)
    Last edited by olive (2012-04-27 20:33:59)

    There's not much you can do to make HTML5 videos as fast as Xv, see http://swfdec.freedesktop.org/wiki/FAQ. They are slow for the same basic reason as Flash... the video overlay cannot be used because the standard allows for controls and CSS to be rendered on top of the video.
    As for redirecting to an external player... this is not as easy as it could be. If the videos appeared in <embed> tags or <object> tags, one could use Mozplugger, Media Player Connectivity and other programs, but I don't think one has been written to handle the <video> tag. An upcoming update to firefox will make it use gstreamer, however. If this still results in slow playback, it will at least make it easier to use an external player. I imagine you would have to patch firefox to make it use a port on the localhost as the video sink instead of the screen. Then you would run gst-launch to receive that RTP stream.

  • CORBA - tnameserv uses too much CPU time

    The tnameserv we are using from JDK 1.3 uses a lot of CPU time.

    I think if you want commercial performance you need to purchase a commercial product like Visibroker.

    Apple mobile device service uses too much cpu time, from 88% to 99% of the CPU time.

    The best way to fix this is to completely remove all aspects of iTunes then reinstall. Step by step directions are on this article. Good luck

  • T420s: Conexant Audio Message Service consumes a lot of CPU time in Windows 8

    Hi,
    I have here two models of T420s running Windows 7 and Windows 8.
    The Windows 7  model is quiet and the Service Needs no cpu time during idle.
    The Windows 8 model is noisy (the fan is Spinning) and the Conexant Audio Message Service (Version 1.6.0.0) is consuming 30% of cpu during idle.
    Any suggestions?
    Solved!
    Go to Solution.

    Pretty sure you can just disable the service. I did on my W520 with no ill effects.

  • Syslogd daemon take lot of cpu time arounf 50% of cpu utilization.

    syslogd daemon problem it take lot of cpu time arounf 50% of cpu utilization. How do i solve this issue without reboot.

    You can try then a "/etc/init.d/syslog stop" and "/etc/init.d/syslog start"
    This is only a solution which perhaps will solve your load problem. But obviously
    you should investigate why you have this strange behavior.

  • Plugin-container.exe is using 90-100% CPU - even while running Firefox in safe-mode. Can I fix this?

    I am using fire fox 5.0 (after using 3.6 for what seems like forever) and the plugin-container.exe has been sucking up my CPU power like a vampire. It had been doing that in 3.6 but not as much. I figured if I upgraded the problem would go away, but no, it has not. After reading some other similar posts, I ran Firefox in safe mode with no plugins running and sure enough after browsing for a bit it started running slower and used 90-100% of my CPU. Is there any way to fix this issue? Or am I doomed? Thanks in advance for any help you may be able to provide.

    That's supposed to show you the problem isn't Firefox, don't know how successful that actually is. You can delete it so that it starts up again. Susggest restarting Firefox when you see it has used about an hour of CPU time as the next hour of CPU time will take shorter to get there and you will be locked out.
    Also see this -- the solution on all the items seem to fix a lot of problems with the places.sqlite database.

  • Advanced queue taking a lot of CPU time

    hi ,
    My application has a workflow which dequeues messages from an advanced queue.The message is simple text message. But i am facing CPU time problems. when the workflow( one of the steps is to dequeue) runs it uses 100% of a particular CPU.
    can somebody throw some light on the things to implement to reduce CPU time and why i am having this problem.
    also , i am using the TOP command on UNIX to trace the process.Does it give us the correct CPU usage measure?suggest some more specific measures , if any.
    Thanks in Advance

    Hi,
    I came across tip for speeding up OpenLdap a while ago, I have never tested it as I have never found the need to but here it is :-
    Stop the OpenLdap service
    Open slapd.conf which is under SharedServices\openLDAP\
    Locate
    *# Indices to maintain*
    index objectClass eq
    index cn,ou,cssIdentity,member,cssRoleDN,cssProductCode,cssVersion eq
    index cssDisplayNameDefault eq,sub
    and add
    index uniqueMember eq
    Save/Close
    run slapindex.exe -f c:\<location to slapd.conf>\slapd.conf
    Start up OpenLdap service again.
    Though this doesn't explain the reason why you are suddenly getting performance issues, do you have a large amount of native users/groups ?
    If you are on 9.3.1 have you tried Sync Native Directory from Shared Services.

  • Spotlight endlessly indexing and mdworker process using lot of cpu

    Hi, I just did Archive&Install from Tiger to Leopard, applied 10.5.1 and now...
    ...since THREE DAYS Spotlight is indexing giving strange values for time remaining (2.134.545.673 hours).
    Like I found in other threads, I have the mdworked process absorbing a lot of cpu power and, from Console, maybe it's crashing repeatedly. I made private of lots of folders but the problem is still there.
    Any other idea?
    How can I find which file/application is freezing mdworker and making Spotlight so unuseful?
    Thanks in advance
    Tampano

    I don't know. How much data is on your HD? Simplest thing to do is use the Terminal command mdutil to erase the current indexes and rebuild them. This should do it:
    *sudo mdutil -E /Volumes/(asterisk)*
    Launch the Terminal.app in /Applications/Utilities/, copy & paste that command into the window, hit the return key, enter your admin password at the Password: prompt (carefully because nothing shows up on the screen), and hit the return key again. That should erase the indexes and rebuild them.

  • Kpowersave and hald use alot of cpu-time

    I having some big problems with Kpowersave (0.7.3-1 from aur) and hald start using around 60% of my cpu-time, and will continue to do so until i restart the Kpowersave process.
    This seems to happend randomly, but around every second hour or something.
    It also seems like conky for example starts to take more cpu-time (like 10%) at the same time... Suggest that Kpowersave isnt the one to blame?
    The computer is a Dell XPS m1330 with a Intel core 2 duo T7500 cpu.
    Don't know what more information to supply, and where to start looking. Anyone understand the problem, and have an idea where to start searching?
    Excuse my poor english.

    i would use klaptop-daemon, i'm finding it more usefull and customizable, not quiet a fix for your problem, but using another program would maybe do the trick as well, klaptop-daemon is in the aur repositories

  • Sockd process uses a lot of CPU time

    Hi,
    I'm running the Sun Java System Web Proxy Server version 4.02 on a SunFire V210 dual processor box running Solaris 10 with the default socks5.conf for testing.
    Just browsing a few web pages in Firefox or IE using the socks proxy boosts CPU usage from the sockd process to a staggering 50% and stay there for several minutes.
    Comparing with the old NEC reference Socks5 daemon the Sun version is really performing badly.
    The system is pretty standard though I have tuned /etc/system and the tcp stack using recommendations in the proxy administration manual. All Solaris 10 patches are installed.
    prstat output:
       PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP
    24519 proxy    6664K 4384K cpu1     0   10   0:11:18  50% sockd/43Any ideas what's wrong or do I have to stick with the old NEC reference daemon?
