Hi, Just compiled and try gcc 3.0 stable. And the results is very big surprise! It makes *SLOWER* code! test file: (opendivx with postprocessing, this stuff is written in C) # mplayer -osdlevel 0 -nosound -benchmark 1800.avi -vo null -pp 15 VIDEO: [divx] 640x352 24bpp 23.98 fps 1865.1 kbps (227.7 kbyte/s) hardware: celeron-2 600 @ 900MHz (100MHz FSB), 256MB RAM (PC133, at 2/2/2) (sse,mmx,mmxext enabled) gcc 2.95.2 result: (flags: -O4 -march=i686 -mcpu=i686 -pipe -ffast-math) BENCHMARKs: V: 5.087s VO: 0.001s A: 0.000s Sys: 0.013s = 5.101s BENCHMARK%: V: 99.7160% VO: 0.0258% A: 0.0000% Sys: 0.2582% = 100.0000% gcc 3.0 result: (flags: -O4 -march=i686 -mcpu=i686 -pipe -ffast-math) BENCHMARKs: V: 5.194s VO: 0.001s A: 0.000s Sys: 0.013s = 5.208s BENCHMARK%: V: 99.7309% VO: 0.0221% A: 0.0000% Sys: 0.2471% = 100.0000% yes, speed diff isn't big, but i was prepared for big speed boost by 3.0, and then i got speed loss! :( if i recompile C-only parts of decore with intel's commercial C compiler (free beta available for linux), it's about 15% faster: icc result: (optim. flags: -O2 -fp -rcd -tpp6 -xiMK) BENCHMARKs: V: 4.415s VO: 0.001s A: 0.000s Sys: 0.013s = 4.429s BENCHMARK%: V: 99.6676% VO: 0.0290% A: 0.0000% Sys: 0.3034% = 100.0000% A'rpi / Astral & ESP-team -- mailto:arpi@thot.banki.hu http://esp-team.scene.hu _______________________________________________ Mplayer-users mailing list Mplayer-users@lists.sourceforge.net http://lists.sourceforge.net/lists/listinfo/mplayer-users
