Also PF is not running on either client and servers for tests.

I also try these tests:

net.inet.ip.maxqueue=300 -> 1000

and

kern.somaxconn: 128 -> 512

In any case, what I see is that I can't pass 5.8Mb/sec on the old i386
server and 9.0Mb/sec on the HP145 AMD64 one regardless if I use 100
parallel connection or 400. More then 400 really put all numbers down
and delay, lost, etc.

No, but I will. I am really looking for any ideas as I am at a lost and
I will use heavyer clients to be sure it's not the problem here.
