The Calculation engine in 2007 can be faster than 2003 (depends on the
details of the workbook etc), but Charting and VBA are substantially slower
than 2003.

XL 2007 SP2 improves the speed of Charting but its still slower than XL
2003.
Much of the VBA slowdown in 2007 is bypassable with careful VBA coding.

See http://www.decisionmodels.com/VersionCompare.htm for a more detailed
timing comparison.

Hi, i've read several articles comparing Excel 2003 to 2007, microsoft say
2007 is faster because it uses multi cpu cores etc, but what have people
on
this site found in there day to day use of them both? Im using 2003 and i
don't wish to upgrade if its a snail.

Thanks, Shane.
