Assuming I'm translating "test like this" to the right sort of stuff :)
If one wants to see the effect of different buffer replenishment strategies, I
suppose that some netperf tests could indeed be used. It would be desirable to
look at service demand moreso than throughput (assuming the throughput is
link-bound). TCP_STREAM and/or TCP_MAERTS. I'm not sure the extent to which it
would be visible to a TCP_RR test.
Differences in service demand could also be used to measure effects of irq
migration, pinning IRQs and/or processes to specific CPUs and the like. The
linux processor affinity stuff in netperf could use a little help though - it is
easily confused as to when to use a two argument vs three argument
sched_setaffinity call. I suspect one may also see differences in TCP_RR
transaction rates.
I suspect some high number of confidence interval iterations might be required.

i'd trim individual names from the dist list, but am not 100% sure who is on
netdev...
