Hi all,
I would like to know if there is a way to identify which query steps are slowing down the overall refresh time of my queries. I've been doing some reading and suggestions vary a lot, with no clear guidance on how to actually measure and identify slow query steps.
I know join/merge operations will slow down things. I also know from experience that comparing lists with the default List.Difference and similar operations are a burden too. I avoid all of this operations and try to sort the dependencies of the queries so it doesn't call the data source multiple times for different queries. I've tried table / list buffering but Im not sure I fully understand what they do...and I think neiter does the people that recomends their use haha.
Still, some of the queries are really slow. Any suggestions?
Thanks!
