[CalendarServer-users] Limitations on number events?

Wed Feb 11 12:54:11 PST 2009

I had similar issues with large calendars and 1000+ events. In your  
case is does look like it is timing out:

> [80504.2 ms]

That is a really long return time for a request. On my really busy  
server my typical responses are:

> [3195.9 ms]

I'm not an expert yet with the iCal/CalDAV server but am very aware  
that there are a lot of moving pieces to getting it to work and  
perform correctly. I might look through your system log to see if  
there are other issues that might be delaying responses as well. I  
think more RAM might be helpful too as the iCal/CalDAV server spawns  
about 10 python processes that are very short lived but are constant  
and for brief periods (measured in milliseconds or a few seconds) can  
spike the CPU usage.
