I discussed with Markku Vire today some performance-related stuff, and actually this same thing came up. He had taken GTK+ 2.10, ran gtk-demo with buttons and resized the window like mad. Sysprof indicated that some (IIRC) 75% of the time was spent within X (dunno the exact setup). There was some funkyness with expose propagation (fetching a style property _every time_, yikes!) but even if you'd optimize the whole section of GTK+ code to be faster, that would yield a very tiny improvement. So it really seems to be something in the way GTK+ uses X (or graphics in general) . I think I'll try to recreate the numbers too to try to get a handle of what's going on. It would be interesting to see what for example disabling double-buffering on the resized widgets would mean... -- Kalle Vahlman, [EMAIL PROTECTED] Powered by http://movial.fi Interesting stuff at http://syslog.movial.fi _______________________________________________ Performance-list mailing list Performance-list@gnome.org http://mail.gnome.org/mailman/listinfo/performance-list
