Poor GigE Performance

Someone asked me to test the speed of some Devolo 500AV ethernet over mains units I have as compared with some older 200AV units. In preparation I ran a simple test from my desktop box (that I plan to replace) to my server showed a throughput of about 333 MBit/s over a GigE switch. My younger laptop to the same server with a more modern (but still cheap) NIC gets 727 MBit/s to the same server over the same switch.

The desktop is using the common (at the time) Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13) and the skge driver. ethtool reports all is well and that it's running at 1000 Mb/s as expected, but it clearly can't manage that on a simple iperf check.

Now I am planning on replacing the box anyway but just wondered if anyone knows and good tuning tips for Gig Ethernet?
