Here you may see what I mean: > wwwlehre.dhbw-stuttgart.de/~lombardo/spicy_osx.mov It is really slow indeed. One thing you could try to discard the non-gtk part, is to run spicy-stats against the replay tool. You should be able to compile the "replay" branch on https://git.gitorious.org/spice/elmarco-spice.git. Extract http://elmarco.fedorapeople.org/debian.xz. And run server/tests/replay -w debian. Then you can time/profile spicy -p 5000, or spicy-stats -p 5000 (for excluding gtk usage). > This screen recording was done with the lastest pixman (stable), the > latest cairo (stable) and the git clone of spice-gtk of today. > > This is my configuration: > ./configure --prefix /Users/devel/gtk/inst --libdir > /Users/devel/gtk/inst/lib --disable-usbredir --without-python > --with-audio=no --with-gtk=3.0 --disable-smartcard --enable-controller > --with-coroutine=gthread --disable-werror --with-sasl=no --enable-vala > > I tried to keep it as simple as possible.

Well, it's explained above: "spice-gtk only supports sw canvas atm", "replace it at build time, or use a runtime selection". Look at how spicec does it for inspiration, if it can help you. _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
