I have been testing different things with Wordpress lately and the best thing I have tried is using OpenLiteSpeed server and and LiteSpeed Cache. I had about 10 sites on a 4gig ram and 2 core VPS with Apache and it was slow with a high load. Now I have about 15 sites on a 2 gig ram and 1 core VPS and it runs very smoothly with a low load level. None of the sites get very much traffic, so I can't attest to how it would perform under high stress.
