Yes as we discused it there it have quite important effect on compiler
speed.

Here's my benchmark. I used latest libjpeg 0.6 sources for testing.
And I'm very surprised how does it so different even on such fast CPU
as C2D is! Numbers says it clear (make all):
LZMA: 41s
NRV (--best): 21s
uncompressed: 19s
