Use of SET CALCPARALLEL in business rules

Summary: Use of SET CALCPARALLEL in business rules

Content (required): Use of SET CALCPARALLEL in business rules - in business rules that process a large volume of data I was using this setting for performance. Recently end users have reported a large deterioration in performance, i.e. 30 seconds becomes 6 minutes. And looking at this setting I found that it was making matters worse, such that removing it improved processing time, though this was not consistent between Test and Production pods, with all other things being equal (testing out of hours with identical data sets)

I did have calcparallel set to 6, now 2 seems to help, but not to restore the original performance.


Howdy, Stranger!
