As far as I can tell Facebook use memcached so extensively that practically everything is served out of it, so their bottleneck could well be the PHP application code as opposed to the data fetching. In any case, when you're serving potentially millions of page views a second even a small optimisation can save you from buying a ton of extra hardware. |
