The common wisdom has been that FreeBSD 4.11 is faster than 5.4 on
single processor systems.  Imagine my surprise when I went and
actually benchmarked this on the package build machines, and found
that 5.4 outperforms 4.11 by at least 10% when performing identical
workloads on identical UP hardware :-)

Stay tuned for more details...
