i had the same beef with it and i went back to using xquartz with dwm and urxvt. The reason why it's so slow is very simple. It's basically an nstextview derivate. To be fast it needs to fill the buffer and render it offscreen in fixed intervals. a lot of osx programs share this problem. there was an ancient vnc viewer called vncthing that easily beats every osx vnc viewers performance, because of that.
