> sys 0m0.090sfwiw, compiling xterm patch #165 with just the wide-chars option, and comparing against xterm #243, I'm not seeing much difference (less than 10% variation). That's with a 24x80 screen. Running it in a UTF-8 locale bumps the numbers up by about 10%. Also rxvt-unicode is giving me slightly higher numbers than xterm. (This is on a new xterm - I'm aware that the performance of scrollback is unchanged-sometime I'll have 2-3 weeks in one chunk to rewrite that...) Attaching the non-UTF-8 numbers to give a comparison (bug report only shows POSIX locale - I used en_US). -- Thomas E.
