I'm > not sure, but in my math class .1 ms is faster than 1ms. 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 ) ... JG
