Whats taking up all my memory?

Nothing out of the ordinary there, I don't think. Even though, given
the fact that you seem to have a quite fast CPU I'd expect the id (idle)
column to be at 100 more often :} The box SHOULD be bored out of its
tree most of the time. As far as interpreting the output goes: just
read vmstats man-page ;}

Your readahead on your disk setting is set to the default of 8 sectors .

Change it with hdparm -a xxxx where xxxx is a big number because it should then set it to the max possible for your drive.

You might get a value something like 3 times bigger

- like 60MB/second

or more.

Your drive isnt maxd out IMO

Hmmm ... from man hdparm

Code:

       -a     Get/set sector count for filesystem read-ahead.  This is used to
              improve performance in  sequential  reads  of  large  files,  by
              prefetching  additional  blocks  in  anticipation  of them being
              needed by the running  task.   In  the  current  kernel  version
              (2.0.10)  this  has  a default setting of 8 sectors (4KB).  This
              value seems good for most purposes, but in a system  where  most
              file  accesses are random seeks, a smaller setting might provide
              better performance.  Also, many IDE drives also have a  separate
              built-in  read-ahead  function,  which alleviates the need for a
              filesystem read-ahead in many situations.

I'm not sure that heading for the biggest possible value is necessarily
a good idea ;}
