Thanks Ryan - awesome as usual and well worth the wait!
It's probably worth mentioning that the reason number_to_currency is popping up is because the example page isn't doing much, so the time spent in the call becomes significant.
We'd probably see a more significant improvement in performance if your action wasn't shelling out. eg. if you just ran some ruby code or returned the contents of a file instead of starting a sub-shell to get the process list.
Thanks for the screencast!
