Thanks. setting its performance a bit less helped tremendously. I had a full quest log on my main, with dailys, outland quests, and a few plaguelands quests I never finished (Nathanos Blightcaller, and Alexi Barov, and the battle of darrowshire) and when it had to do all those quest paths, along with the shared lowbie quests, it killed me. Now it works fine, albeit with a bit of lag time when quests are added/updated/completed, but no biggie.
