Bug Description

I have just set up Sunbird. I have it connected to 17 Google Calendars, none of which are massively full of events, and some of which have almost nothing in them at all. We are talking here about a combined total of 400 events, or a lot less even. Yet every time I do the simplest thing, such a toggling the show/hide option, Sunbird takes several seconds to redraw the display and CPU time shoots to 40% on my 2-core 15GHz processor. CPU usage is very high quite a lot of the time actually, although I have not worked out what else is triggering it.

Obviously this figure is way too high and close to the upper limit of usability, and it needs to be brought down a lot.
