I posted this on usenet but got no reply anyone care to give an answer?
I have just run lmbench on my pentium FreeBSD-stable box.
Ok, I don't expect my box to be as fast as an HP snake but I did not
expect it to be 24 times slower than Linux on Local TCP connections.
Anyone any ideas whats going on, 100 kb/s is not exactly pushing the
boat out?
*Local* Communication bandwidths in megabytes/second
