If your default cache size is 75, then you're not using SuperServer with its shared cache. Even with a cache per process, 75 is very small for a modern machine. In general, database cache is a good place to use memory. A RAM disk for temp space will help when the query requires sorting (order by, group by, distinct) but not much otherwise.

Good luck,
