I'm not using a hacked version of netperf. The 50,6 has been there a long time so I'm not sure where I took it from any more. It might have been an older version or me being over-zealous at the time. > PS - I trust it is the receive-side throughput being reported/used > with UDP_STREAM :) Good question. Now that I examine the scripts, it is in fact the sending side that is being reported which is flawed. Granted I'm not expecting any UDP loss on loopback and looking through a range of results, the difference is marginal. It's still wrong to report just the sending side for UDP_STREAM and I'll correct the scripts for it in the future.
