the description "poor network performance" is quite vague, therefore: - Can you provide any measurements? - iperf results before and after - statistics about dropped packets (rx and/or tx) - Do you use jumbo packets? Also help would be a "lspci -vv" output for the network card and the dmesg output line with the chip XID. Heiner
