I've seen workbooks that can take over 30 minutes with any update- not just
copy/paste, but even changing cell values- generally, because there are a
lot of complex formula (Vlookups, etc.) in the workbook that keep
recalculating. It seems to be worse if the formulas are all inter-related,
(change Formula1 which changes Formula2; I'm guessing that because Formula2
changed a workbook cell value, Formula1 has to be recalculated even though
it hasn't changed, and so on).
One possible test that comes to mind is to hit F9 ("calc now") and see how
long it takes to recalculate everything in your book. However, I don't know
if that is a comprehensive test especially if cell values themselves haven't
changed- I don't know how Excel decides what to calculate.
In any event, if you have a more than a nominal number of formulas in your
workbook, try adding some vba code to turn off calculation before your
operation, then back on after. If you are pasting to a worksheet that is the
source for /any/ of your formulas you will still have to recalculate anyway,
so don't forget to do that at the end.
airball code:
Sub pasteMyStuff
Application.Calculate = XLManual
'Joel's code to paste in one action
Application.Calculate = XLAutomatic
'possibly force a calculation here if needed
End Sub
