it would help if you posted the formula..
and explain how the data is organized (sorting, alpha(numeric) etc)

but yes.. i'd say array formulas on multiple columns
on 10000 rows of data takes processing time.

also you do not say if the arrayformula is entered in
an array of cells or just returns 1 value in 1 cell.

possible scenarios:
add a "helper" column with true/false formulae
then do a simple sumif.

write a custom function in VBA
(possibly not fast enough..)
