Haven't you read benchmarks in mplayer-dev list? It IS the case here.
Binary compiled with gcc4 is faster than the one compiled with gcc3,
which is faster than gcc295 binary.

I also noticed speed improvements in mplayer when going from 2.96 to
gcc3 some years ago. Haven't used mplayer in pre-2.96 times (before mid
2002) and noticed no improvement when switching from 3.2->3.3, 3.3->3.4,
3.4->4.0, so can't comment that.

I still have 3.2 and 2.96 installed on my system, so I can do some
benchmarks too if you doubt that..
