How much swap?

Yes exactly :)

I used to use tmpfs but I stopped doing so for two reasons.  These reasons 
are important to me but they may not be as important to others...

1. tmpfs on Linux does not support quotas.  I mostly admin on multi-user 
boxes and I don't want users being able to individually fill /tmp.  This 
gives all users a bad day.

2. I haven't found a terribly huge performance improvement in using tmpfs. 
this is mainly because only a minority of file writes occur in /tmp.

Yeah tmpfs can be used in places other than /tmp but in general these 
points still apply.

This is why I've stopped using tmpfs.
