I don't quite follow your conclusion from your data.
While there was a sweet spot for the 1400 rr size, other
smaller rr took a hit.  Now all the tps changes were
within 1 %, so perhaps that isn't considered significant
(I'm not qualified to make that call).  But if that's
the case, then the effective latency change seen by the
user isn't significant either, although the amount of
queuing in the NIC is admittedly significantly reduced
for a rr size of 1400 or larger.

Tom point was to show that we can reduce latency (because size of
netdevice queue is smaller) without changing tps ;)
