I am using a SUMPRODUCT formula, or rather several of them in a workbook that is greatly reducing its efficiency. Here is the formula:
Is there an alternate formula that i could use or optimizations I could make to make the workbook more efficient. I have tried using the "--" vs the "*" but it does not seem to make much difference if any.

Maybe to try with COUNTIFS
Edit: Something like this
=IFERROR((countifs(Dump!$V$2:$V$20000,$B$23,Dump!$AB$2:$AB$20000,G$23,Dump!$F$2:$F$20000,$B29,Dump!$Y$2:$Y$20000,"Technical")/countifs(Dump!$V$2:$V$20000,$B$23,Dump!$Y$2:$Y$20000,"Technical"),"")

Ok, I am going to convert all of the formula over now, to see if it improves performance.
Is the divisor part constant in all of your formulas? i.e. this part?
=SUMPRODUCT((Dump!$V$2:$V$20000=$B$23)*(Dump!$Y$2:$Y$20000="Technical"))

No, the divisor will vary.
