We (Newton Group) have ported the netperf client to the Newton O/S - a
small, threaded, resource constrained, system (deceased). Given that the
Newton o/s dosn't have a file system or any system level (c++) user
interface APIs and it has a set of entirely unique system and TCP/IP APIs,
it went quite well - it took about two-three man weeks. I would have thought
that the client could be ported in less time & less hassle for VxWorks.

We found it very useful in driving through-put issues and assessing
bottle-necks - we got up to the blistering rate of ~1Mbit/s using 10Mbit
PCMCIA ethernet!! - mostly limited by bus band-width.
