You guys aren't touching on an important point:

This is NOT Ethernet traffic.  This is loopback traffic!  (see Subject:)

Given the same hardware, FreeBSD will generally go faster than Linux for
most real networking tests (ok, fine, _all_ of them that _I_ have seen
that were executed in an unbiased manner).  However, the difference in
speed seems to be magnified somewhat on the loopback interface :-)

Anyways, the fix to this fellow's problem is obvious:  Press the Turbo
switch or set your CMOS configuration to start the machine up in non-Turbo
mode.  Then your FreeBSD box will (probably?) go slower than your Linux
box.

( all sorts of :-)'s )
