I recently ran across an article linked from news.com discussing a study
on memory vs. disk performance. They found that databases designed to be
kept entirely in RAM were at least an order of magnitude faster than
disk-based databases that had sufficient RAM available to keep the
entire database in cache. Of course, the catch here is that MUDs
typically use custom databases rather than a general-purpose DBMS and
may not be subject to similar degrees of difference. Anyone else see
that article and still have the address?
