Hello, First of all please do not interpret this post as a troll post - it is absolutly not my intention to blame anybody for the great work on gtk or to spread FUD or whatever. The following lines are just experiences of mine, so not valid in general and not ment as troll stuff... I am using GTK since a long time (both coding gtk applications and using gtk based application) and I think GTK is a great toolkit - however I am experiencing performance problems since GTK-2.0 and first I thought this is just because tons of unoptimized code since so many functions have been re-implemented. However now we are at 2.6.? and I still do not see significant performance improvements. I also have seen several applications which are cross-toolkit or which switched from gtk-1.2 to 2.x.y and they all perform better with gtk-1.2 or the other toolkit. The GTK2-port of SWT/Eclipse for example is the slowest port of all swt ports (win32, mac, motif, fox, gtk2) and since mozilla switched to gtk2 their interface is really sluggish on my Authlon-800 although I have an 2d accerlated nvidia card. The bug-report which (among others) mainly adresses GTK2 performance problems is the report with the second most votes of all eclipse bugs: https://bugs.eclipse.org/bugs/show_bug.cgi?id=37683 They also profiled GTK and found out that for eclipse the problem mainly lies in pango. I already tried recompiling GTK not thread safe but it didn't help a lot :-( I would be really interrested in helping to speed up GTK, however I am a bit concerned wether tuning the x11 based backend does still make sence now when GTK is switching to cairo as rendering backend. (are there any numbers how cairo does influence gtk's performance?) Are there any know performance problems where man-power is needed? Thank you in advance, lg Clemens _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
