Vav,
this looks normal for linux. the load on your box is so low it looks like
its asleep. :) i have boxes at work and home that both do the same thing.
linux is just being very, very generous with the allocation of buffer cache.
if you really want to get brave, you can change that value in the /proc
directory with sysctl. i think its /proc/sys/vm/buffermem. it would be a
good test to see if you grab back some memory. just a thought.
