Because of the seemingly uninformed remark about it and xmms? > The x11perf is just for comparison with some model system, I presume. If the bandwidth to the framebuffer is low, that may explain at least some of the slowness you're seeing (apps using the RENDER extension slow to handle expose events). > And the comparison of sawfish with metacity makes it quite clear that > metacity is slow.

I can't seem to tell much difference between metacity and sawfish here (except that opaque window resizing works much better with metacity :), YMMV. -- Earthling Michel DÃnzer \ Debian (powerpc), XFree86 and DRI developer Software libre enthusiast \ http://svcs.affero.net/rm.php?r=daenzer
