Well, not nessecarily Messages, but an application called IMagent is using more than 100% of my CPU (possible?).  I'm just giving you guys at Apple some feedback, so hopefully you'll fiz it when Mountain Lion comes out. http://cl.ly/3T0k162n1a1v020R3m2s

    You are correct, IMagent is the process used by Messages.

     

    I noticed that as well when I first installed it when the beta came out but its CPU usage went back to normal after a day or two.

    On a side note.

     

    The 100% refers to one core.

     

    If you have more cores then the figure can seem strange as it lists higher figures than 100%

    I find it's CPU usage to be fine, but it swaps really heavily occasionally until my computer runs out of disk and the whole thing comes to a halt.

    During video chats, it spikes to 300% utilization on my i7.  Definitely a beta :-)

    HI,

     

    iMac i5

    Screen Shot 2012-03-04 at 9.37.19 PM

    Spikes at 46%

    This is more likely to be something else such as Effects and Backdrops that are trying to run as well.

    Nope, just a video chat.  As soon as the video window closes, it drops back to normal.

    Hi,

     

    I would check Console for any Messages about iChat or Messages  (in some Logs Messages is refered to as iChat 6.1)

    I'm seeing the issue as well, there's nothing in the logs, and I'm not using any video filters with the video chat. (It also doesn't happen in facetime just the ichat style video chat).

     

    I'm assuming they're just making the lack of video acceleration in ichat prior to the early 2011 macbook pros (and friends) worse.

    HI,

     

    I initially launched the test Account Video chat from my Buddy list

    I have checked about starting from the Messages window (You have to send text and th Apple Test Account don't respond to text so you are just filling their Desktop)

     

    However using this and typing spaces or full stops (dots) I could launch Video Chat this way.

     

    I am still only just getting over 43% CPU usage. with occasional spikes to just over 45%

     

    I would see if changing the iChat > Preferences > Video Section Bandwidth Limit to 500kbps makes a difference.

    I limited it to 500 kbps and it made no difference.

     

    What made a huge difference was the size of the window, and whether I was showing local video loopback as well as the chat video. with only chat and the small est window possible, the cpu usage was about 39%, with both video loopback and chat video (fullscreen) the usage was at about 160%.

    Hi,

     

    This is weird as I cannot replicate that even if I Show Local Video and go Full Screen (I was showing Local Video before).

     

    I even changed from calling one of the Apple test Accounts to calling my other computer (jsust to see if Interent speed made difference.

     

    I managed to see a peak of 52% at Full Screen whilst sliding the Chat to one side to see the Activity Monitor.

    Like I said, no GPU involvemnent on my mac, so every pixel is being pushed by the cpu, which means the bigger the window (and the more video sources) the more cpu will be used.

     

    Apparently the 2011 MBPs have moved the video work to the gpu for ichat, so my next mac (which will be a 2012 or `13) will be fine.
