This question already has an answer here:
While running Virtual Box my system is accessing the hard drive a lot and running slowly.
When I checked system resources using System Monitor it shows processor usage at 15%, RAM usage at 65% and Swap usage at about 50%.
My question is why does ubuntu need to use Swap when there is sufficient amount of main memory available?
free command -
total used free shared buffers cached Mem: 4075908 3056931 1018977 0 1944 308408 -/+ buffers/cache: 2746579 1329329 Swap: 4139004 1862551 2276453
Virtual box seemed to work just fine before I upgraded my
12.04 Precise to
12.10 Quantal. Now its so slow its almost useless.
