I would rather say that Clean has a better tradition (as can be checked when you look 10 years past)
on the Mac.

On the Mac, as John posted, there is also a 3 fold speed up between no-blocking and blocking.

The result on a 450 Mhz PowerPC G4: (1000 x 1000)

old version: 52 seconds
new version: 19 seconds
new version: 13 seconds with code generator that generates fmadd instructions.

Only on the Sun. But it speaks for SAC that you can give the compiler option "blocking on/off"
without the need to re-write the program.
