I'd like to add that this problem still persists under Horde Groupware  
5.2.0. and Kronolith 4.2.0. Has anyone found an explanation yet - or  
means how to prevent this from happening? I have two Google calendars  
with around 2,000 entries each and server load shoots through the roof  
and the Horde portal page always aborts loading due to timeout when I  
activate the two in the settings...
