I have a 2.5 MB addin that I work on quite a bit (I use CodeCleaner on
it every so often).

On my primary computer, a desktop, I have excel 2002, and saving the
file takes about 18 seconds.

On two laptops I have excel 2003, one with no SP and one with SP2, and
saving the file takes 2 seconds! A huge difference.

I just installed excel 2003 SP3 on my primary computer, and save time
only improved a little, to around 14-15 seconds.

Can anyone suggest why such a huge difference in save times? I'd sure
like to get the desktop to save the file in 2 seconds.

All the above computers run Windows XP. The save times are quite
consistent and repeatable, pre-compiled or not.
