Formula Processing
Certain formulae seem to take longer to process than others, is there a schedule of formula run-times ... e.g. DSUM vs SUMPRODUCT with D.U.O.?

RE: Formula Processing
Hi Gareth
Thanks for getting in touch.
I'm not aware of a 'league table' of formula processing time. You are right; some do take longer than others. Some of them are call other functions in the background so on a lot of data can see a significant delay.
Two ways to increase the speed of formula execution include: converting to an array (or CSE) formula often sees dramatic improvement, or using VBA to access the data directly without having to use the Excel interface. If you are experiencing noticeable slowdown executing formulas, a custom VBA routine or function is probably the way to go.
Kind regards
