[Mplayer-users] Too slow playback, how to estimate speed gap?

I have MTRR compiled to in kernel, but there is no /proc/mtrr, so my guess 
is that Crusoe doesn't support it...?!?

Ok, I will try this next with Cyrix MediaGX, if it has MTRR-stuff, altough 
it's only 300MHz, but I have a gut feeling that it should be a bit better 
with video stuff than Crusoe.

I'm running mplayer with -vo fbdev -ao null -dvd 1 /dev/dvd -benchmark

The benchmark gave me the following numbers:

BENCHMARKs: V:  2.000s VO: 0.000s  A: 0.080s Sys: 38.246s = 40.326s
BENCHMARK%: V: 4.9596% VO: 0.000% A: 0.1973% Sys: 94.8431% = 100.0000%

What do those numbers tell about my systems performance? Do they give any 
promise that a 600MHz Crusoe would do better? Or did I execute the 
benchmark incorrectly...?

PS. I tried mplayer also with 300MHz Cyrix MediaGX, but that simply sucked...:(
