I did overall performance benchmarks for them and they're all slower
than the C  version. My first benchmark (under MPlayer) was with a
--enable-debug compile, the differences were somewhat bigger with a
default compile. The first and second alternatives (P3:683 and P3:680)
were around 1% slower, the other 3 over 2% slower.
