I recently configured urxvt to use an Xft font, specifically LucidaTypewriter. I noticed after doing so that font rendering is extremely slow -- Page-Down'ing a manpage takes 25% of the CPU, whereas using the Fixed font uses 0% of the CPU. Also, when conky is configured to use an Xft font, it uses about 4% of the CPU (0% when using the Fixed font). Navigating a web-page that uses an Xft font gives major lag.
Why is this? I'm using OpenBSD 4.3. I can provide a dmesg by request.
