I test the whole thing, because i have very slow nfs (udp) performance
(it is in real about 25mbit/s). So i found out, that the bottleneck lies
between my server and my firewall(router), because the udp ttcp
test from client to my server was ok (~90mbit/s), between my client
and firewall it was ok too, but not between server and firewall...
So atm i have no ideas, what it could be...
