If you are seeing 30Mbit/s on a Gigabit connection, then my vote still
goes to packet loss. I'm seeing ~25MByte/s on writes against a filer
when using 2.4.19 (and about 40MByte/s on reads).

When you did your ethereal test, did you run on both the server side
and the client side at the same time in order to compare the number of
packet send/receives that they see? Have you tried TCP?

You haven't mentioned which kernel you are running, or what your
.config file looks like, so I can't answer your question concerning
the load increase.
