Tough question. Apart from Darac's considerations, that'll depend much
on your calculations: if the working set of your application can grow
into more RAM, the cache hit ratio might diminish. Whether this results
in a slowdown overall will depend on processor, memory architecture
and application in pretty complex ways.
