If you want to get even a little more performance out of it, look into PHP APC (alternative PHP cache). You can configure W3 Total Cache (or similar plugins) to store their cached files within APC (which will be in-memory). Though, since the cache files on disk will be already cached in memory, this may not be all that much faster. APC is a nice alternative to dealing with something like memcache (since you are working on a smaller scale).
