Attached are sample logs during high CPU usage on iCal open.
Yup looks like iCal is making way too many PROPFINDs and the server is having a hard time keeping up. When the server starts up those PROPFINDs are executing in about 30 ms which is about right. But after a while the time starts to increase a lot, in the worse case taking over 6 seconds. That seems to start happening when the number of requests per second increases (gets as high as 40+ per second). In theory we should be able to cope with that particularly on a 4-core system so we need to analyze this some more. Right now if you want to have a usable system you are going to have to restrict the number of delegates that people setup because that is causing iCal to do all those PROPFINDs. -- Cyrus Daboo
