I heard redirecting stdout/stderr to /dev/null can also speed such tasks
as kernel recompiles on such beasts. The actual compilation becomes I/O
bounded and eliminating the output to the screen reduces some overhead. I
can't try it right now (not at my machine), but supposedly some vendors
use this trick to speed up their quoted SpecMarks. Anybody for a try?
