[Mplayer-users] Benchmark: mplayer compiled with GCC 2.95.4-pre vs. GCC 3.0.2-pre

[André Dahlqvist]

Hi guys,

I did a somewhat different benchmark, comparing mplayer compiled with
gcc-2.95.4-pre with gcc-3.0.2-pre. I did the benchmarks with different
codecs as well too see if one codec was considerably slower or faster
compiled with either of these compilers.

Below is the result I got. Basically it's a very close race. To my surprise
gcc-3.0.2 is overall a tiny bit faster than gcc-2.95.4. Not noticable to
the user of course, but it's still a sign that gcc-3.0.x is improving it's
code-generation quality. I should add that mplayer took ~1 minute longer to
compile with gcc-3.02 than gcc-2.95.4.
