Right.  The tlp should perform better than the rtk; they are both
100mbit/sec interfaces but the tlp is significantly less burdensome
on the host cpu, which is almost certainly the bottleneck here.

This test is getting and putting files from the disk drive.  I am
not surprised that a very old PowerBook cannot send data it has to
read from its internal hard disk faster than 27Mbit/sec.

A better test would be to use ttcp.
