Hmmm, should be going for treasure goblins within kill radius, but I may have missed some names for them. I'll see if I can find some more treasure goblins and check their "backend" names!
As for the speed - to be honest mine runs smoother *WITH* the plugin than without :O I find default DemonBuddy gets very very laggy with lots of monsters on-screen, especially with corridors/obstacles nearby and elites. I've tried to improve this as much as I can - I'll certainly look into ways of caching data to try and make it even faster, but I don't think it can get much quicker without some core changes to DB!
You have to cache Unit Data to write any decent combat routine adjustments
