Ooops, ok I think I just missed your proposal, Kumar. Anyway, I'll post my benchmark results to this here:
1.- mplayer -nosound -benchmark testfile.mpeg (a DVD-mpeg2 file): No fix at all: VC: 30.5s VO: 53.4s Sys:1.95s Total: 85.8s First fix (force writes to way 0): VC: 24.3s VO: 40.6s Sys:1.95s Total: 66.9s Second fix (implementing lrw): VC: 23.1s VO: 31.5s Sys:1.03s Total: 55.6s Third fix (patch v4, lrw in SPRG6): VC: 21.055s VO: 28.289s Sys:0.972s Total: 50.316s 2.- prboom -timedemo doombench1 (where doombench1.lmp is prerecorded demo): No fix at all: 14.1 fps First fix (force writes to way 0): 16.7 fps Second fix (implementing lrw): 18.1 fps Third fix (patch v4, lrw in SPRG6): 19.9 fps 3.- Synthetic and pathologic memcpy() benchmark: No fix at all: 26 Mbyte/s First fix (force writes to way 0): 160 MByte/s Second fix (implementing lrw): 163 MByte/s Third fix (patch v4, lrw in SPRG6): 180 MByte/s Best regards, -- David Jander Protonic Holland. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
