I'm not sure if Ravelry uses it, but it seriously cuts down on your database usage, which speeds things up - and the beauty is you can run a bunch of 512mb or 1gb memcache servers on your www or whatever boxes and they all appear as one big giant cache to the application servers. I'd seriously suggest checking it out if you haven't already. :)</p> The percona builds are indeed very nice - I’ve played around with them in development for my site (modthesims2.com), but one of the major things I’ve found to help is not actually changing mySQL at all… but using memcached.

Very interesting to see the Alexa 10,000 stats - particularly the percentage of users from other countries… I didn’t even know there was a Azerbaijan!
