Today I tried the network performance of MPC8313ERDB rev.C, Linux 2.6.23 (the last) with iperf on a Gigabit Ethernet connection.
I'm suprised at the poor performance:
with MTU 1500 (both sides) - 278 Mbits/sec
with MTU 9000 (both sides) - 321 Mbits/sec
Does anybody make some network performance tests?
