Sure; the puppetmaster processes are quite heavy. Right now I'm running with a MaxPoolSize of 10, fitting nicely into the 2.5GB of reserved memory. > * PassengerStatThrottleRate 600 > I haven't noticed this make a *huge* difference, but logically we > don't need to stat for the relevant files at all really. I think it's best to actually disable RackAutoDetect & RailsAutoDetect, but I'm not sure if disabling them will avoid the stats. > * PassengerHighPerformance > Turning this on appears to reduce performance for me. Interesting. From the docs I'm not seeing how this could decrease performance. Anyway, hosting puppetmaster doesn't need any rewrites or something, so turning it on/off shouldn't hurt operations. > * PassengerMaxRequests > I'm trying to work out at the moment whether we're leaking memory at > all with 0.24.8, but even if we're not, I can imagine this making a > big difference for certain usage patterns.

On my setup the puppetmaster processes stay between 200-300M VIRT, and don't grow larger, so I haven't looked at this at all. > * PassengerPoolIdleTime > The default is 300 seconds. I'm yet to look into this setting. I'm running with the default here, but still get long lived puppetmaster processes. Probably they never get idle. > * RailsSpawnMethod > * PassengerUseGlobalQueue Haven't touched these at all. Thanks for your feedback!
