Both exist :) Anyway, thanks for doing all those tests! >Frames per second from agg-gtk -v profiler.swf, first 10 tests on a 1700MHz P4 The problem with this fast CPU is that it becomes hard to profile. The CPU is so fast that the movie reaches it's nominal frame rate of 120 frames per second. More than 120 fps can't be configured unless we tweak Gnash to run as fast as possible (w/o caring about framerate). I did my tests using the FB GUI on a 800 MHz Geode. I'd say that any reported frame rate above 100 fps should be treat with care. Sandro proposed to use a "real profiler". Unfortunately I have no experience with them and I think that, just like gdb, it makes it more complicate to do some overall speed tests. Probably it's more useful once we know what version is slower. >cvs20070509 >Doesn't run profiler.swf (shows yellow circle with border and pauses forever >using 0 cpu) Huh!? It runs fine here. Did you try to run it again? >cvs20070516 >Doesn't run profiler.swf What happens? >cvs20070528 >122 89 104 58 107 120 123 101 89 103 >122 91 109 93 102 123 124 100 88 97 >123 91 109 85 91 111 123 91 66 75 Are these three test runs of the same Gnash version? Test 10 shows very different values.. Sure nothing else on your system took much CPU time? Sure the window has always remained fully visible? >Running 20070509 on the frame buffer reveals no change in speed since 9th May: Very strange. I'm doing a fresh checkout in a new dir right now to avoid any mistakes on my part. However, 90 fps on a 1.7 GHz machine is very slow. I guess your system simply can't measure more precisely. Add a break; in fb.cpp line 347 (right after the while). This will make Gnash take as much CPU as it can and allow frame rates far above 120 fps (theoretically). Test 1 goes up to 1400 fps on my Geode after doing this patch.
