I don't know about you but since I started using an archck kernel, I have
always seen my system actually using swap. The swap prefetch patch seems to
be working here and I don't mind at all. In fact it makes my system much more
responsive.
Here is the current free -m report.
$ free -m
total used free shared buffers cached
Mem: 495 485 9 0 61 131
-/+ buffers/cache: 293 202
Swap: 768 241 526
Now imagine that if I didn't have any swap space, that 241MB would have either
been eaten up from my RAM or those files would never have been cached. In
first scenario, it would reduce the capability of my system to cache the
important files in RAM b'cos it is already full with not-so-important files,
while in the latter case the Disk IO on my system will increase whenever I
needed those not-so-important files. What ever your choice might be, I
personally choose free RAM for better caching of files + lesser Disk IO, even
if that means spending 768MB of HDD space.
