Toke -

The script looks reasonable.  Certainly cleaner than any Python I've yet 
written :) I might be a little worried about skew error though (assuming 
I've not mis-read the script and example ini file).  That is why I use 
the "demo mode" of netperf in 
http://www.netperf.org/svn/netperf2/trunk/doc/examples/bloat.sh  though 
it does make the post-processing rather more involved.

I see you are running the TCP_RR test for less time than the 
TCP_STREAM/TCP_MAERTS test.  What do you then do to show the latency 
without the bulk transfer load?

You may find 
http://www.netperf.org/svn/netperf2/trunk/doc/netperf.html#Omni-Output-Selection 
in 2.5.0 and 2.6.0 helpful when it comes to getting netperf to emit 
specific measurements.

I was thinking of trying to write a version of bloat.sh in python but 
before I did I wanted to know if python was sufficiently available in 
most folks bufferbloat testing environments.  I figure in 
"full-featured" *nix systems that isn't an issue, but what about in the 
routers?

happy benchmarking,

rick jones
