[linux-audio-dev] GTK performance?

Hi all! The other day I dressed up my application with a fancy g5-ish pixmap theme. Looks good and expensive :) As it turned out, it really was expensive (counting cpu-clocks.) Using Page Up/Down to manipulate a scale, I get 100% cpu at times when the the scale is at max (respectively min), hence no redrawing should take place (because oldValue == newValue.) I then measured X using an Xterm, holding down a key to get the key to repeat. Really, no sweat! Just a srolling window with gibberish. So X is as far as I can see not at fault. Is it gtk then? Or the pixmap engine? I thought I'd go and listen to the horses mouth and fired up The Gimp ... Uhmm! Those guys really do not wish to use the pixmap engine and replaces the scales with what comes out of the eazel-engine (Crux & friends.) With key Page Up/Down and the eazel-engine, I still get 20% CPU. This is kind of expensive for essentially doing nothing. My conclusion is that there is something deeply wrong inside gtk, regarding handling of signals and/or redraw. This is bad news for RT audio people using gtk. In comparison, letting FlightGear redraw the polygons of the Himalaya ranges looks kind of cheap :-/ Comments? Reference machine: 1.1Ghz Celery. Gtk-2.0 -- ( ) c[] // Jens M Andreasen
