--- Comment #6 from John Layt <john layt net>  2010-09-15 16:09:15 ---
I've prepared some fixes in the 4.5 branch to KODayMatrix, KOAgendaView,
MonthView and ActionManager which should help.  I forgot to test the response
times in 4.5 before the changes, but it was snappy afterwards.  However
backporting to 4.4 conditional on KDEPIMLIB_VERSION didn't completely resolve
the delays so the Working Days code is probably still an issue there and I
don't see an easy/clean way to patch that.  

Instead I've gone back to trying to improve KHolidays performance by
implementing an optimisation to only parse the file for the calendar systems
actually used in the file, reducing most calls to only parsing the file once
instead of 11 times.  Testing with the kdepim 4.4 and kdepimlibs combination
the response is snappy again so I'm hopeful this will resolve the issue.  The
fix will be in the 4.5.2 release scheduled for 2010-10-05.

I'll post the 4.5 patches to ReviewBoard for comments anyway, then look at
trunk to see if the patches are appropriate there.
