FYI, we did some profiling as well for the 770-platform, Gtk+2.6 vs Gtk+ 2.8. There's some huge slowdowns, and it seems it's because of the float stuff in Cairo... We don't have an FPU in the current 770 hardware, so... (in the report 'hard float' means using the kernel fpu-emulator, while 'soft float' means that the compiler 'inlines' floating point handling code - much faster) Here it is: http://maemo.org/community/gtk_vs.html Best wishes, Dirk. _______________________________________________ Performance-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/performance-list
