Tried to test my freebsd 8 system and noticed that speed on gigabit lan max comes to 600Mbit/s, at the same time on Ubuntu server I have 900Mbit/s. In these tests I used the same machine and iperf. I was testing using GENERIC kernel and all options by default. Man's about optimization didn't give the result.
Where could be the problem?
Intel server board G7ESZ
lan NIC - Itel Pro/1000Mt Dual Port Serer Adapter (em)
Where could be the problem?
Code:
Freebsd8(PC1)<====Ubuntu(PC2) iperf = 600Mbit/s
Freebsd8(PC1)<====Freebsd(PC3) iperf= 500Mbit/s
Ubuntu_server(PC1)<=====Ubuntu(PC2) = 900Mbit/s
Mandriva(PC4)<====Ubuntu(PC2) iperf = 960Mbit/s
Machine:
