Not getting gigbit from a gigabit link?
- by marcusw
I just upgraded my LAN to gigabit. This is what netperf has to say about things.
Before:
marcus@lt:~$ netperf -H 192.168.1.1
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.1 (192.168.1.1)
port 0 AF_INET : demo
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 10.02 94.13
After:
marcus@lt:~$ netperf -H 192.168.1.1
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.1 (192.168.1.1) port 0 AF_INET : demo
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 10.01 339.15
Only 340 Mbps? What's up with that?
Background info: I'm connecting through a gigabit switch to a sheevaplug. I have Cat5e wiring in the walls and the run is maybe 30 feet. If you're not familiar with netperf, it has a tendency to give very stable results and never lie.
