[CalendarServer-users] Mac OS X Server

I ran iCal Server + iCal in a test environment on a older Xserve--Dual
G4 1GHz 2GB RAM Mac OS X Server 10.5.5--in this test environment with
only a couple of test users and I noticed a significant increase in
CPU activity due to iCal but it seemed that it wasn't something the
server couldn't handle. A month later when I rolled out the service to
60+ users the server was brought to its knees. It ramped up to 100%
CPU usage as more users logged in and by about 11AM that business day
it ceased to be functional. Anyone trying to connect timed out before
they received updates.
I have not been able to track down any specifics as far as something I
can "fix" to prevent this problem as my iCal Server install is Apple
default and other than running the CPU load at 100% there was not a
single error reported/logged. I'm going to use brute force to work
around the issue but I would like to find a better approach.
I am going to try to roll out this service again later today/tomorrow
but hosted on a brand new Xserve 3.0GHz Quad-Core Intel Xeon 16GB RAM
(I'm lucky in that I work for a bunch of lawyers).
I'll let you know what I find out and/or what happens.
