[MTOS-dev] InnoDB performance

This post by one of the tumblr developers sheds light on a pretty
incredible bug we've seen recently in which InnoDB occasionally
under-performs MyISAM by a factor of 5 or 10.

It just goes to show how difficult to isolate performance issues are.
In addition to the web server, templates, third party plugins, etc.
Sometimes you hit an unforeseen bug in something completely external.

I'm wondering if some of the (incredibly) slow queries we've seen come
out of MT haven't been as a result of this issue.
