Looks like it is because of your Set Filters. If you remove all filters that are Sets, and recreate them as either a calculated field or a normal filter, I believe you will see your performance increase.
Yes, Joe. You are rigth. In a couple of dashboards I change the Set Filters and now the query takes less than 1 minute.
It was just the reverse I've thought. I believe Sets will help me to do a better job because the query will be ready with the set. Begginers errors. Now I will avoid them.
Thank you very much,
