Again highly inaccurate.  Run wmcpu sometime on a workstation that
only you are using.  Note the CPU load meter at the top.  Note how
there is usually ZERO CPU activity, and that most of the rest will
occur while accessing the drive (if you have IDE disks).  No matter
how good it is, no optimizer can achieve a 5% speedup on a program
that spends over 99% of its lifetime idle anyway.
