Excel 12 is quite a lot slower than previous versions with VB, but maybe the
SP1 update due out next week will improve things.

Standard speedup tricks - you need to
- read and write many cells at once using Variant=Range and Range=variant
- uninstall Google Desktop Office COM addin.
- switch off screenupdating and automatic calculation

I created vs for excel 11.81 on an NT box then loaded it onto a new
version
of excel on Vista. The execution performance is an order of magnatude
slower
in Vista and the new version of excel 12.06.
The code is simple formating and reading from one sheet and writing to
cells
in another sheet in the same workbook.
Both systems are dual core with the same memory. Vist has faster
processors.
Any configurations or tricks on using the new excel on vista?
