OK, one problem that I introduced. I was running a niced seti during
the runs on both the Linux and FreeBSD box. It looks like the "niceness"
on FreeBSD is problematic.
New numbers without seti:
Linux - 39 minutes
FreeBSD no tweaks - 43 minutes
FreeBSD memory tmp - 38 minutes
Looks like the systems are pretty close. I just need to remember to kill
seti on FreeBSD before compiling. :-)
Now if I can figure out the eepro100 problem, I can do this SMP.
