It now seems to be able to sustain around 30meg/sec the highest I have seen I havent done any other testing so if you have a better way it would be good to know thanks. Please bare in mind I have no local access to the server so crashing it eg. is expensive for as will have to pay for a kvm switch netstat -i indicates no collisions for a duplex mismatch so not keen on trying a manual negotiotian again for reasons above. So even for a card with no hardware features you would expect it to exceed 200mbit easily? I havent enabled net isr setting I wonder if that will help. Chris
