[MPlayer-dev-eng] bsd vs. linux - encoding benchmarking

[Arpi]

Hi,

http://www.bsdnewsletter.com/2003/10/Features110.html

this is a very interesting article.
our old bsd friend, Steven M. Schultz made a benchmark testing on varions
bsd systems and linux, doing the same dv->mp4 transcoding using various
tools including mencoder.

the only thing i don't understand: how can it be so much faster on linux,
than on *bsd ? as the most time consuming part of the encoding is done by
the decoder and encoder, and just a little part (file io) depend on OS.
my guess is that some optimization was disabled on *bsd, maybe SSE and such.
also, the above article doesnt include the actual command lines used for
transcoding, so its not clear if ffdv or qdv or libdv was used for actual
decoding.
