Istvan,
I ran newer FreeBSD code 8.0 RC1 this time. By using NetPIPE, we collected
test data and the result shows that FreeBSD TCP performance is worse than
Linux. I got troubles to plot using gnuplot, so here I am attaching the raw
data files.
The netpipe commands are as follows:
PC2: #NPtcp
There are two gettimeofday calls, one at the beginning of the test and the
other at the end. netperf-2.4.4 is used. I believe gettimeofday is a
vsyscall in linux, but a real system call in freebsd.
Thanks,
Steve

Did you compare syscalls made and time taken?
For example, do either/both of them do a lot of gettimeofday() calls?
FreeBSD and Linux have (had?) d
use netpipe TCP pls.
And graph it.
Thanks in advance,

I compared TCP performance between FreeBSD and Linux by running test tools

The kernels are full version and default values are used in the testing
