I've been looking into ways of improving performance lately, and many times I look at raid situations for obvious reasons. I wanted to point out a method for reducing the amount of bandwidth during combat with lots of people around. Some of you might already be aware of this, but I would guess many people aren't.
If you aren't interested in seeing the spell flavor text for spells being cast and wearing off, disable those messages under Chat Options. Instead of forcing them to another tab that you don't look at, make sure they are not checked on any of your chat tabs. This will tell the server not to send them to you at all, and should save a decent amount of bandwidth during combat.
The same thing is true for all chat messages. As long as the messages are going to ANY window, the server will send them to you. If you disable them from all chat windows, you won't receive them at all.
With the new Connection Stats window, you should see a drop in your BPS during combat if you disable some of these spammy messages.
