For the last few weeks my game has suffered severe performance issues, to the point where having roll20 open slows down perf on other sites and programs. Very laggy when moving around the map or moving tokens. I've scoured the forums here and tried everything I've seen (removing characters, shrinking maps, clearing cache, etc etc) with little-to-no apparent change. Are their any other tips&tricks to investigate what's going on? My players are suffering the same thing.
