Caching cuts down String#scan calls by ~30% and produces no perceivable difference in scrolling responsivenes. After String#display_length caching the main cpu hog is Ncurses::WINDOW#method_missing, which dispatches calls to wide char or ordinary Ncurses methods depending what's available. Gonna try to hardwire Ncurses::WINDOW#mvaddstr next. > Looks like I just haven't done enough scrolling to find that out. :-O Now that I really look into this. The performance I see (sup runnin screened on Bytemark VPS) is considerably better that what is seen on the video. It is definitely not fast, but otoh I can't make it lag behind like it does on the video. -- Tero Tilus ## 050 3635 235 ## http://tero.tilus.net/ _______________________________________________ sup-talk mailing list sup-talk@rubyforge.org http://rubyforge.org/mailman/listinfo/sup-talk
