"ethfast" looks like a 10/100 driver though it says "link up > 1000 Mbps". What kernel modules are you loading for both cards? lsmod shows e100 and e1000e. I don't think I've done any customization related to these modules.

Thank you so much for the diagnosis; the network problems have been driving me nuts, but the server is the last place I thought would be responsible. Perhaps this also has something to do with fact that throughput has topped out at 300Mb/s, and that imposes a high CPU load on the laptop.
