How does these cool web site doing performance testing? Do they use any open source load generator like Jmeter/Grinder? Or they have their own ?eat own food?)

Yes, this question is a little sensitive but it may bring people some ideas of how to do the performance testing even better.

Not specific on preformance testing or tuning, but maybe useful. How Facebook Ships Code (framethink.wordpress.com/2011/01/17/how-facebook-ships-code). It has been modified because the 1st version is over-exaggerated.
Thanks! Will read this post soon.

Not quite Facebook/Twitter but Atlassian have made public some of their performance testing techniques that they use for JIRA and Confluence, you can read about them here
