Right. I now have the runner script parsing netperf demo output and
aligning the time steps, complete with interpolation and everything (I
think; I've looked at the numbers and it seems reasonable, but I'll try
graphing the raw numbers along with the interpolated values and see if
it looks good there too). I've tried running it with a long _RR test and
then after a few seconds starting the _STREAM and _MAERTS tests. That
produces output like the attached table.

The next step will probably be adding some kind of graphing capability;
probably using matplotlib. It should also be fairly straight forward to
add parsers for different kinds of data, time series or otherwise. But
that will probably be something I'll look at as I need them, and/or when
I get around to poking around Dave's test repository.

Anyway, feedback is quite welcome. Running the sample config files in
the repository should be possible by just changing the -H parameter for
netperf.

The code is, as before, at: https://github.com/tohojo/netperf-wrapper
