I use quite a lot of addons and was wondering how much “memory used” is considered too much? Currently my addons sit around 108 MB of memory. The addons WeakAuras 2 and Details use the most memory. I haven’t really noticed a performance issue in-game, but I do get an on-screen notification that certain addons may be slowing down the game.
Depends entirely on your system. If you’re not noticing performance issues I wouldn’t worry about it.
