My previous spreadsheet developed with excel 2000 is very fast compared to a
very slow 2007. the file is over 100 meg with a lot of formulas, pivot
tables. plotting is extremely slow with 07 and excessively slow when
opening/closing grouped rows or using filters. Although I've turned off
background error checks and even auto calculations it still appears there's a
lot of recalclations going on in the background with 2007. xcel 2000 doesn't
do this and is very fast. I don't know what to try next...helpppp--

I must be the luckiest XL 2007 user in the world because I see these posts
constantly and have never experienced performance degradation on my workbooks.

In any event, here's an informative white paper about Excel 2007
performance: http://msdn2.microsoft.com/en-us/library/aa730921.aspx

thanks for the white paper, it gave some ideas but it hasn't solved the
problem. It states that with 2007 some formulas are volatile, they
recalculate even though you're using manual. does anyone know how to turn
this feature off on 2007. I'm really disappointed with the speed and the
filter functions of 2007
