Hey Edwin, sorry, I didn't see your last question.

I'll try and confirm but I've seen loss in both
directions but it's not clear whether that's significant
enough or not yet.

e.g., TCP traffic is retransmitted, so it could be segments
lost while outgoing or acks lost incoming.

4407 retransmitted TCP segments
130 TCP timeouts

in stats collected about 5 mins apart - which isn't
sufficient a sample size, we're trying to get a new
collection of stats, logs using the netperf TCP_RR test.

In our case, note, we're more concerned (and have more solid
data) of latency issues than dropped packets (which I expect
some of with heavy network testing).

For example, netperf TCP_RR latency is about 70-78% of the older
systems for 1,1 request/response byte sizes as well as 64/64,
100/200, 128/8192 sizes.

I'll update here as soon as we have more data from the production
environment.
