Windows Calendar is VERY Slow

[Kevin]

Hello,

I have a brand new computer which I have a clean install of Windows Vista
Ultimate (there is no other software installed and I've barely used it so
let's assume no possibility for viruses and such) and I am currently having
no specific problems other than the following:

I have opened Windows Calendar and imported a .ics file which is a calendar
I had been using in Outlook 2007. This file is about 320 kb in size. The
calendar spans a period of 2 years and probably has an average of 10
appointments per week.

My problem is that using this calendar is EXTREMELY slow. It is slow in
everything I do with it (changing dates, changing properties, creating new
entries, etc.). For example, it seems to take 5 to 10 seconds just to select
an appointment.

Sorry for a general lack of detail, but anyone have any ideas of things I
can look into as to why this is so slow?

Thanks! Kevin

could be because of the size of the file and number of appointments.
mine is for 6-9 months and 5-10 appts per month and it is fast.

Hmmm... I guess I wasn't thinking this was much; I mean, any less stuff and I
probably wouldn't need a calendar..

Of note, I'm going through and "cleaning" the calendar a little bit, and I
really only have about 1 year of stuff (not 2 like my op).

I would have to guess that there are too many appointments and the size of
the DB is slowing down the app. That's just a swag, though, as I don't use
Calendar at all. Have you tried creating a new calendar? (Again, not being
familiar with Calendar, I have no idea if that would help. I think only if
the new calendar used a different data store.)

Maybe the import from Outlook's DB screwed things up... sorry, not much
help, I know...

So, I think this is simply a matter of there being "too much stuff". Which is
lame because I really don't think there is much in this calendar, and Outlook
had NO problem handling this (actually with more information).

I cleaned up the calendar a little bit and then moved appointments to one of
7 different calendars to act as 'categories'. I then backed these up and
deleted one by one. As I slimmed this down to one or two categories, the
performance of Windows Calendar became satisfactory. I then re-imported all
the calendars and had the same slowing affect.

So, what I am doing now is turning off half of my calendars depending on
what categories I want to see, and this is working OK.


- NEW QUESTION -

I am trying to find a way to 'select' appointments in a date range and then
delete these. I am wanting to do this in order to improve performance.

Thanks!

I want to relay something to you that may have a bearing but not a hint of a
solution for your problem.

I am using Visual Fox Pro 9 as an xBase Oledb accessible database for some
purposes. It necessitates me to have VFP9 development Studio or simply
Browser on the ready. When I first installed it in Vista (as opposed to XP
where I never noticed the problem) I was shocked. Some of the windows moved
very slow, with weird traces and if you jerk them too fast they would bounce
back and you have to start doing it over again.

I posted this on their forum and the pros just sneered at me, although I
suspect those people have never been close to a Vista computer. They just
laughed me off. Then another guy came up with the same problem. Voila! I was
not a liar anymore but so what. No solution. the problem is that MS would be
happy to forget about VFP.

I think it is because MS does not care about OE anymore. It has been stated
that Windows Mail is the way, am I correct? They just forgot to test if your
calendar. is Vista compatible. perhaps there are a 100 users out there who
do it, so what?

This theory does have a weak spot. It does not explain why others do not see
this problem. Perhaps there are some other differences in parameters or
whatnot, who knows.
