</div></div>Okay, I so followed your link and picked this one from the search results:<br>
<a href="http://www.bsdcan.org/2013/schedule/attachments/242_BenchmarkingFreeBSD.pdf" target="_blank">http://www.bsdcan.org/2013/schedule/attachments/242_BenchmarkingFreeBSD.pdf</a><br>
<br>
So that's 2013, and clearly tons of good work has gone into producing<br>
the slide deck.<br>
<br>
However, it's a 4-core machine he used. It seems to me that this<br>
hardware is apples to oranges to what Francois used. Am I wrong? Is<br>
there a better, more recent benchmark from FreeBSD with a more<br>
comparable machine?<br>
