Addons that cause extra latency?

[Jonexe]

I've been using Mazzle for a while now (still love it, even with patch 2.2), but since that horrible voice chat patch, I've been having a large amount of latency. Of course, my ISP and Blizzard tech support are useless, as per usual.

Now for my actual question, is there any addons that Mazzle comes with that could be causing me to have an extra amount of latency? I'm sure something like the one which pulls in quest text from WoWhead would, but are there any others? I'm hoping that maybe I can reduce some of my latency issues that way, in order to get the game back to a playable level.
