    Just wanted to report that I'm having this same issue and is across the whole computer - all video (flash, itunes, quicktime) suffer from severe sporatic slowdown.

    Come on Apple, give us a fix! Very disappointing...

    Another user with very sluggish performance on my 27" iMac. With iTunes and Firefox open my Wired memory usage is 800Mb and my Active Memory usage is 1.2Gb. If I close everything I still have 1.1Gb of Active Memory being used (info coming from iStat Pro).

    It seems that the memory is not being released by the applications. I'll try some of the recommendations about sleep / airport but come on Apple, I think it's clear a pattern is developing by now!

    I went to the Melbourne store today with XBench on my USB stick and got seriously terrible results from +every one+ of the three 27" iMacs on display (all default build). For comparison, I benchmarked the MacBook Air with SSD nearby and it beat the 27" iMac on most of XBench's statistics. Something is wrong with the line in general. Let's hope Apple patches it soon!

    I just got my new 27" and it had a broken screen (exchanged it) and now the replacement will not let me raise the audio with the keys and can not be found on bluetooth. Also it got very hot during a workday. Love the screen but hope they jump on the issues. I had to drive over 100 miles to replace the computer I had already paid to have shipped over 2 days. But I do love apple!

    The same in here. Take a look at these photos comparing my MBP and my Imac 27" activity monitor while in youtube playing the same video.

    I got reply from AppleCare and they said that as for my issue(Slow down of flash streaming and hickups with AirMac ON), it is concerned with AirMac driver and they have solved this issue on 10.6.2 update. So I will just wait for the OS update(They said it'll be veeery soon but cannot say exact date though) for my comfortable AirMac life for now...

    I hope this information makes some people happy, not worrying our choice had been bad one..
    At least, I am relieved to hear that they have been aware of these problems, making good effort to recover.

    Sorry, "AirMac" is the name for "AirPort" in japan.
    So, the point is that the issue should be related to AirPort Driver and it will be fixed in the coming os update, our AppleCare has said.
    Wait and see how 10.6.2 works for us...

    Looks like Apple just released the Mac OS X 10.6.2 update. Looks like it addresses this issue with flash video playback on the new iMacs

    Please see if you can follow this best practice for the update:

    • Complete a full Time Machine update.
    • Ensure all Apple applications are in their default locations e.g., Safari and Mail are in /Applications etc.
    • Quit all applications.
    • Run software update from the apple menu to start the Mac OS X 10.6.2 upgrade.

    I've just installed 10.6.2 and it doesn't make any difference to the Flash video playback problem - still get same >100% on the CPU. Oh well, roll-on 10.6.3.

    I had the same problem on a 27" imac and now, after the update everything is ok.
    Do the update again.
    It was 499.9 MB.
    On my macbook pro it was only 147 MB.
    Another option is to download the combo update from the apple support page - http://support.apple.com/downloads/

    You've carbon copied this response to umpteen different threads now, yet your profile says you are a Windows user? So are you talking about Flash on Windows or Flash on OS X? Almost everybody is stating that the issue is fixed. That would seem to indicate you have a completely different issue going on. What Mac did you install 10.6.2 on? Or are you running it on generic PC hardware. We can't help until we know exactly what's going on. Fill us in please.

    We're waiting to see if you consider the problem RESOLVED with today's upgrade OS X 10.6.2. Hopefully you've been able to confirm the problem is fixed and if so, please mark the thread RESOLVED before too many more impatient people ditch their new machines or change their minds about making a purchase. I think Apple has demonstrated in the past the the .2 or .3 version of a new major release brings much more stability than the .0 and .1 releases. Sure hope so because I expect to be ordering my iMac when (these major issues are fixed and) people have provided positive performance feedback on their new machines.

    It appears that my problem largely remains. There are only 2 applications where i use flash.
    (1) Youtube... now approx 40% CPU usage... showed marginal improvements (-3 to -5%)
    (2) Restaurant City (Facebook) by Playfish... still approx 140% to 150% CPU. .. no improvements.
    Overall CPU usage still exceeds 110% especially when Restaurant City is running.
    Whats happening? Need help here.
