Once we got our Passenger config options in the right place our compile
time went down by about *2/3*! Our CPU user stats seem to have gone up
a teensy bit but overall load average is about the same.
To complicate matters (or kill two birds with one stone :), when we
switched to Passenger we also switched to RubyEE.

FWIW, here are our options:
PassengerHighPerformance on
PassengerMaxPoolSize 24
PassengerPoolIdleTime 1500
# PassengerMaxRequests 1000
PassengerStatThrottleRate 120
RackAutoDetect Off
RailsAutoDetect Off
We were running 10 puppetmasterds with Mongrel. With Passenger we
usually see 6-8 running.
