I recently disabled swap and mounted /tmp on tmpfs for a netbook since the SSD is so slow, and now I'm wondering if that would be a wise move for all of my Gentoo systems. In what type of situation would it be a bad idea?
Instead of disabling swap, just make it small (like 32MB or something; whatever the smallest allowable partition size is). The kernel needs swap to operate optimally, even if it's extremely small. Just make sure it's there.
Mounting /tmp as tmpfs improves speed, so no problems there. You might want to mount /var/tmp/portage as tmpfs too, that will give nice speed gains during emerge (if you have the RAM for it; a 2GB /var/tmp/portage should be enough for almost anything except OpenOffice, you'll have to umount to emerge that one.)
