I am working on 10G Ethernet driver. On 2.6.17 and earlier 2.6
kernels, I could get 7+ Gbps running TCP netperf on 4 CPU system.
With the same driver, the transmit performance drops to less than
5Gbps 2.6.18 kernel. Are there any known performance issues going
forward to 2.6.18 kernel?
Any area I should look into? Any input is appreciated.
