Comment 43 for bug 788102

Chat window open is about the same as no chat window in Firefox. However chat window minimized look like ~100 ms more.

For whatever reason my Safari performance has tanked though and isn't so useful - it's 2700 ms now without a chat window and 3000 ms with one open. Wish I could tell you why it tanked.. (reset just about everything, restarted and shutdown as well). I'll pipe up again if things look any different.
