Disabling Safe Sleep 

I'm pretty happy with my MacBook Pro, but it seems to take a long time to sleep. I'm guessing this is partly due to the fact that it has safe sleep enabled — the contents of RAM is written to disk (and then can be read back in upon waking). I don't think there's any UI to disable this, but from a Terminal window you can type

sudo pmset hibernatemode 0

I haven't tested to see if it's actually faster, nor have I verified whether RAM was being written encrypted or not. But I should now be faster, and at least as secure.
