        You are using 112940k for cache hard drive reads.  If you need 
it linux will just free up the cache memory as the cached data on the 
hard drive.  In the minds of the linux kernel designers unused memory is 
wasted memory.  Remember that reading a file from ramis many times 
faster than the drive.
