Another tool you may want to include in the Rails Performance Tools section is request-log-analyzer. I may no be fully objective as the author, but I think the reports it produces are superior to the other open source tools available like rawk and pl_analyze. Moreover, no special logger is needed and it can be easily adapted to specific application needs.
