I connected a system to the same VLAN as the calendar server,
calendars with about 1500 events work some of the time but take
sometime. 3000+ event calendars still do not work at all.
I will move a few of the large calendars to a almost unused similarly
spec'd system to see if a single user downloading the calendar works.
Has there been many tests of large calendars + iCal clients?
