It seems like all of my dashboards run a bit slow to downright no fun. I do use report templates and the section auto update every 5 minutes. I was beginning to wonder if it really makes a difference whether I show all incidents in a fixed area or if I limit a page to say 5 incidents. I have done zero tests so far. I kind of hoped that someone has already run into this and has a handful of suggestion to making a quick dashboard.
I just upgraded from a SQL 2008 cluster to a private instance of SQL 2012 with GB RAM. That has made a significant improvement but still the dashboards seem sluggish. Console doesn't seem to be nearly as bad and it is showing exactly the same dashboards.
