Yes, but you omitted the socket buffer size, which also has the
affect of causing netperf/netserver to make fewer syscalls
(which is probably the difference).  Try sendfile again
with Rick's suggest socket buffer size.

Also, do you have a receiver which has a decent 1GbE interface
you can pair with this?
