I don't have specific numbers of expected latency and resp-per-sec,
but your results seemed something we'd not expect for a reasonably
working server. This may probably due to the excessive overhead of
P1/P2, so you may also try recent beta versions.

FYI, this is an example result for my test box, where resperf reported
a maximum throughput of 23858qps:
