OMG, what a relief... the ~30% diff in performance was due to a BIOS =
setting, in particular this one;

Intel Turbo Boost Technology
Enhanced Intel SpeedStep Tech

I disabled both.

In fact, FreeBSD is showing a tad better now then CentOS.  I have files =
if any one is interested in viewing.

Thanks to all for the rather overwhelming response :)

Actually it was good that hardly any one did as it forced me to debug =
the old fashioned way :)
