2010/11/18 RLW<seran...@o2.pl>:
there is no tcpbench in packages for 4.8 and for debian linux
Because it's in base: /usr/bin/tcpbench
ciao,
david
I removed Intel NIC and run test on broadcom integrated Gbit NIC to see
if there is problem with em driver

so... the same machine, different NIC, different testing programs, same
behavior (~50% of defined queue speed, very high CPU usage)
the only thing i can try now is moving intel nic and hdd to other
computer with pcie slot and run test on it to see is it hardware
(motherboard) problem.
