The incredibly slow speed of Apple's 10.2 Terminal app when antialiasing is enabled has annoyed me for months. In my mail window, I've turned off line wrapping and scrollback in an attempt to speed things up – it helps, but not that much. I had assumed it was a CoreGraphics font rendering problem, but I discovered today that it's not.

An article on Apple's x11-users list mentions that you can get vanilla xterm to use FreeType, and thereby CoreGraphics font rendering under Apple X11. xterm -fa Monaco -fs 12 reacts instantly, at least in comparison with Terminal's horrendous 0.2-second response time, and looks identical save the weird X scrollbar.
