If you look at the output of 'free' or the top few lines of 'top',
you'll see that Linux will use a great deal of your memory for buffers
and cache space. I've also got 256M of RAM, and currently 6M are in
buffers and almost 88M is used as cache space. Linux will automatically
reduce the cache and buffers as other processes grow and have need of
the space. Basically, all that unused RAM is being put to good use,
to speed up things as much as possible. So it's definitely nothing to
be worried about.
