Question

I am currently using a dsum to calculate some totals and I noticed excel has become really slow (needs 2 seconds per cell change).

This is the situation:

- I am trying to calculate 112 dsums to show in a chart;
- all dsums are queries on a table with 15 columns and +32k rows;
- all dsums have multiple criteria (5-6 constraints);
- the criteria uses both numerical and alpha-numerical constraints;
- i have the source table/range sorted;
- excel file is 3.4 mb in size;

(I am using excel 2007 on an 4 year old windows laptop)

Any ideas on what can be done to make it faster?

…other than reducing the number of dsums 😛 ====>>> already working on that one.

Thanks!

Answer 1

Some options are:

Change Calculation to Manual and press F9 whenever you want to calculate

Try SUMIFS rather than DSUM

Exploit the fact that the data is sorted by using MATCH and COUNTIF to find the first row and count of rows, then use OFFSET or INDEX to get the relevant subset of data to feed to SUMIFS for the remaining constraints
