For me the suspend/resume are both faster then turning off/restarting.
The trick was to minimize the things I disable on suspend. I haven't
tested the memory compression yet, it can help if your cpu is fast
enough with respect to you disk.
usb seems to be enough (remember to stop gpm first if its running a usb
mouse). I don't have any pcmcia cards or scsi which are are the main two
other things that have trouble suspending.
The longest thing to suspend is alsa, takes quite some time to stop so I
don't stop it. It doesn't function on startup, but starting xmms after
resume fixes it if I want to re-enable the sound (rare). When I'll have
some time I'll try to see what it actually does.
I'll be happy to hear if it also wakes up some other cards (I have ac97
on-board), could be useful.

Actually, if you want to help, just running swsusp and reporting
problems helps quite a lot. The project needs the qa at the moment.
You can join the mailing list to get information on how to extract the
data for reporting problems.
Replies are quite fast. Nigel (the main developer and project
originator) usually replies in less then a day to most stuff, and most
other people are also quite helpful.
