What does 'free' say? Does 'ps ax' show many processes as SW
(swapped)? Are any of these critical? 8 MB is really a minimal
system. I suspect that you probably could use more ram plus a bigger
swap.
I ran a 486 with 16 MB of ram as a router and it worked fairly well. I
plan to runs a few server apps on it so I recently replaced it with a
P-120 motherboard (which cost all of $50 USD, including 32 MB of ram)
and the difference is noticeable.
