Adding memory over 256MB will slow you down.
Being a machine with two level of cache, filling the cache with
page tables will give a reduction from a factor from 8 to 10.
The limiting factor is the effective bus trueput,
stopping the DMAs can help.
Having a lot of thing in memory is a good idea if it does
not have to be write also to disk, the data have to move twice
on the bus, the CPU is in fact idle 90% of the time.
