Please don't mind me jumping in here and contribute some numbers. I'm
not even sure they are very helpful to you.
I had quite an adventure compiling mplayer (svn) and libmpg123 (1.13.4)
on a very old x86 hardware that I use and a small embedded arm-device.
Although benchmarking on arm may not really fit into the discussion I
added it for your information.
