Hi Douglas,

I encounter the same issues.

I especially can confirm this issue. I took a look at it with some help from 
Volker. 

The default save interval is 1 min. I did a watch on the ical file with: 
watch -n 1 "cat agenda-500-records.ics | grep "BEGIN:VEVENT" | wc -l". This 
showed that every minute there where about 26 records saved. 

So some calculations show: 5600 / 26 = 224 => 224 / 60 =~ 3.6 hour. Seems in 
the same order of magnitude as you reported. After that I attached callgrind 
to the ical resource which showed that QString::operator< is called ~41 
million times in about ~10 minutes.

The callgrind output is attached to this mail (Just for the record, I 
already send it to Volker). Volker do you take a stab at this? If any other 
debug output is needed let me know, I'd be more than glad to produce 
something that might be helpful on this issue.

Cheers,

Bertjan
