How about Gordon's initial bootstone, which increased by 25%?
http://docs.freebsd.org/cgi/mid.cgi?16091.44150.539095.704531

And I just did a "make clean" run in /usr/ports/archivers (by manually
mv'ing a static and dynamic sh to /bin in turn):

static:       96.63 real        53.45 user        39.27 sys
dynamic:     112.42 real        55.51 user        51.62 sys

The wall clock is bad (16% worse) and the system time is worse (31%).


So.. 

1) Microbenchmark:	40% worse
2) Bootstone(*):	25% worse
3) Ports:		16% worse
