I am using slicehost.com 256MB hosting for my site.
Unfortunately it is swapping almost all the time. When I type in console
free i get something like:
total used free shared buffers cached Mem: 251140 228968 22172 0 596 17356 -/+ buffers/cache: 211016 40124 Swap: 524284 60944 463340
reboot the server, the swapping stops for a little bit and then starts again.
How can I:
1) figure out which processes/functions cause the swapping
2) How to fix the issue
3) figure out if 256MB is too little and its time for upgrade rather than optimization
