    NO DOUBT.
    OSX 10.6 + Safari problem.
    When I upgrade 10.6 from 10.5, I see a big difference on flash player performance under same full screen flash website.
    Use another browser would solve the problem.
    It doesn't related to new iMac, it is related to the safari, I have lot of mac here have the same problem including MacPro 8core.

    The problem is Airport.

    If you disable it your are going to see your computer becomes responsive again.
    Another quick fix is to put it to sleep and on again. (it disables the Airport that's why it works).

    Looks like a simple update will fix this, when available.

    PS: I had this problem on my 21' imac and replaced for a brand new one that had the same problem.

    I Agree....I think it's Airport as well.

    Here is what I do that temporarily fixes the slowness problem:

    go to network
    copy my dns server
    go to airport
    click advanced
    click the dns server tab at the top
    delete the dns servers listed
    paste in the one I copied from the main screen

    boom...it's fixed for at least a few minutes. Sometimes longer. Even if its the same number it still works.

    Anyone know what kind of fix it would be? It's really irritating to have to do that over and over all day. Although at least SOMETHING works!

    I get this same problem with my iMac 24" late 2006 model. It hates flash, but it never used to have a problem. Could this be related?

    like i said.... somebody please try and install Leopard 10.5.6 on the new imac.
    it might be something faulty within the Snow Leopard version itself.

    if it works with Leopard then its easier to narrow down the issues...

    I don't think Macs and OSs are backward compatible. Leopard probably wouldn't work on the new iMacs.

    I've been having the same problem on my 21.5", but I don't see a forum topic for my model. Hopefully it's just an issue with airport, and they'll give us a fix soon.

    Nope, I've got a new 27-inch with the 4850 graphics card and my mac is doing the same thing. Frustrating!

    Well this seems to solve the problem on mine :
    - Disable Airport
    - In power settings : disable suspend hd activity when possible

    After 5 hours of webbrowsing (youtube, etc) + music...
    Got over 177 in XBench...

    I don't know how long it will last but at least this seems longer that sleep/wake trick...

    Success! At least so far. When we changed the DNS servers my YouTube video stuttering went away.

    Change DNS servers: System Preferences / Network / Ethernet / Advanced / DNS

    So I talked with Apple tech this morning because I was having the same problems. So far, it's not acted up the whole day!! We'll see about tomorrow, but usually it would get unreasonably slow within 4 - 6 hours of use. Here is what Apple tech informed me to do:

    Macintosh HD>Library>Startupitems then pull Startupitems to desktop. Then Restart.

    If you don't have anything in your Startupitems folder, don't know what to tell you, but this did it for me.

    Cheers.

    It appears to be an airport problem on my machine as well. When the performance goes away, if I turn airport off, then back on, I get back to 'normal' again...
