IMac – After sleep, the iMac is very slow to respond for a 45seconds+

imacmacossleep-wake

When my iMac enters sleep, and then I wake it up — either shortly after, or the next day, while it responds to the wake request quickly, it's basically unresponsive for 45 seconds+ after.

Specifically:

  • Opening a new window for safari (which was still running on sleep) takes forever
  • scrolling in mail will show blank space
  • bringing up Alfred can take a while

Things to note:

  • Late 2010 i7 iMac w/ 1TB disk & 8gb
  • Mavericks w/ all updates applied
  • HD is audibly being hit aggressively

Is this a known issue, and if not, can I run some tools to tell me who is accessing the hard disk.

At this point, I'm considering a new computer, but it seems odd that a i7 w/ 8gb is becoming pretty useless for light email & browsing. 🙂

Leave the Activity Monitor open and visible so that when you wake, you'll be able to see the memory/cpu hogs.
