Well, I have 16MB of main and I am running X if I run the test
without X I get better numbers. 

At any rate, a more relible figure of the raw disk performance
can be obtained by tranferring like 10MB to /dev/null using 
dd. Using a 16kb block size I managed to get 5.2mb/sec out
of the disk on a 10mb transfer to /dev/null.
