> what windowing system are you using? directfb? x11? X11, with no window manager, under MontaVista Linux. Some package details: cairo-1.8.4 atk-1.24.0 autoconf-2.62 automake-1.10.1 bash-2.05b expat-2.0.1 fontconfig-2.6.0 freetype-2.3.7 glib-2.18.1 gtk+-2.14.3 gtkhtml-3.24.0 intltool-0.40.3 libart_lgpl-2.3.20 libpng-1.2.8 libsoup-2.24.1 libtool-2.2.4 m4-1.4.11 make-3.81 pango-1.22.0 perl-5.10.0 pixman-0.12.0 pkg-config-0.20 tiff-3.7.4 > what kind of themeing are you using? Home-grown, but removing it completely (which causes the default look) makes no significant difference. > can you profile things using massif > (memory usage) and oprofile (cpu usage)? No, massif is not available for ARM; oprofile requires Linux 2.6 for ARM support. Thinking about this a different way, is there any benchmark program for GTK? Then at least I could run that against different versions and get a feel for what to expect (we also have a build with GTK 2.10). -- View this message in context: http://www.nabble.com/Embedded-Gtk%2B-system-moving-to-2.14-tp22044752p22059402.html Sent from the Gtk+ - Apps Dev mailing list archive at Nabble.com. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
