    You're right, that's for developers, try this: http://www.apple.com/feedback/macosx.html

    I logged a bug report with Apple at the link above. It's really annoying this hasn't been fixed yet. I can confirm it's not a switch between active/discreet GPU's because I've got a Mac Pro octacore with an HD 5770 (no discrete). Is anyone having trouble with NVidia cards? I looked at activity monitor and there's no drop in RAM performance after sleep, so I'm thinking it has to be a driver issue that needs resolving.

  • lelando04 Level 1 Level 1

    I concur it is ATI-specific. Kind of funny how Apple dropped NVidia because of their poor driver support and then goes and does something completely stupid like this. Two thumbs up. Has anyone had any luck with the iMac Graphic FW update?

    Not ATI spesific; experiencing exactly the same on my mid-2011 MacBook Air 13.3" i7. Would downgrade to Snow Leopard, but the SL installer won't run on this.

  • dembow Level 1 Level 1

    It is definitely not ATI specific as I have nVidia 8800 GS. I would go back to Snow Leopard, but I don't want to lose all the photos, music and app data I've added in the meantime. I guess we'll just have to wait for Apple developers' mercy.

    Thank god for this thread, I thought my brand new Mac Mini was a piece of crap until I read this. I was getting horrible performance in Chrome web browser, page rendering, even just displaying menu's had noticeable lag.

     

    So I decided to reboot the system to see if something strange happened and now the whole system is responsive again. I am turning off sleep until I hear about a fix for this.

  • illis Level 1 Level 1

    Still no solution to this. Things tried so far (at least):

    -new user accounts

    -reinstalling Lion w. restore user account from a Time Machine backup

    -reinstalling Lion without restoring anything from a Time Machine backup

    -resetting pRAM

    -contacting AppleCare 6 times. They gave me a dedicated contact that doesn't answer emails.

    -restarting WindowServer

     

    I've done some benchmarking with XBench. That confirms that the problem seems to affect graphics performance, UI and Quartz tests give horrid results after waking from sleep.

     

    However, it does not affect OpenGL performance.

    Just to add one more thing to the list of remedies tried in vain:

    I disabled resume to see if that was the culprit. No dice.

  • ViktorCode Level 1 Level 1

    The problem appears even without user logging in: just put your Mac to sleep on login screen and after waking it up you'll see performance dropped already. Thus, this isn't something from the user level settings or applications.

  • illis Level 1 Level 1

    I'll have to test that. If I dare, that is – it's too depressing as it is.

  • illis Level 1 Level 1

    Tested: you are correct, there's no need to even login to reproduce the problem.

  • Alley_Cat Level 6 Level 6

    O X 10.7.1 on MacPro 2008 (8x3GHz) with ATI 5770 (had to upgrade from ATI HD 2600 XT to use FCP X).

     

    Potentially similar problems after sleep - very slow browser/app store performance, lot of spinning wheels for no apparent reason.

     

    This was a recent fresh install onto a WD Caviar Black 750GB drive - I trashed an earlier 10.7.0 installation as performance was poor, and have retained my old Snow Leopard boot drive as it's more stable in general.

    AppleCare guy got back to me with an application called Capture Data. I was asked to let it run after the problem has occurred, but it gives an error ("Ditto: can't get real path for source") and never finishes. Nice.

  • Alley_Cat Level 6 Level 6

    You never know that might be a clue to the problem - see if they want a log from the application.

    Sure, I'll check, but that'll take a while - they've been pretty slow with their replies. Not that I'm in the hurry, I've got plenty of time while waiting for my laptop to finish intensive tasks like scrolling a web page. :-)
