10.4: Disable Safe Sleep for faster sleep on lid close
Authored by: dadaDaveed on Mar 07, '07 09:25:11AM

This tip doesn't work on my MacBook for some reason. After entering both strings successfully and rebooting, it still takes 20-30 seconds to sleep. Any idea what would cause these commands to not work? (I'm running a Black MacBook with 2Gb RAM)

Try removing the sleepimage file and seeing if it reappears on the next sleep. This will tell you if the delay is from safe sleep or something else.

If you want to temporarily kill Safe Sleep, try:

sudo rm /var/vm/sleepimage

As others have pointed out, this is the image file. Deleting it won't cause any problems, and has the immediate effect of disabling Safe Sleep until reboot.

I find myself doing this occasionally to free up hard drive space. A temporary solution, I know, but it gives me an instant extra 2GB free.
