Heh. Good point. > Which processes do you see running? puppetmasterds and Apaches or only > one kind of them? By "running" do you mean "busy"? I'm not positive but I think puppetmasterds were at the top of top when we were running Passenger. We're running Mongrel now so I can't double-check. > How long does file serving take for you? Are there very large files? The vast majority are under a meg. The top 15 are between .9M and 7M and only get distributed to one machine. > If so, you might want to test with PassengerUseGlobalQueue on. > > Which versions are your clients? 0.25beta too? The clients are nearly all 0.24.7. Once the file ignore bug (#2358) is fixed we'll try 0.25 on more clients. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
