joerg@laptop> scp otter_machine:/tmp/10mb_file /tmp/
with the 8139too NIC module this takes 8 minutes, 32 second and has about 97500 error on the NIC, all are RC oerruns.
When I do the same with Donald Beckers rtl8139 module then the transfer takes 10 seconds and has about 1865 errors - not perfect but much better.
I dont want to generalize, but for my case the rtl8139 module seems to fit much better.
Thanks for your help Joerg
