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. --- JINMEI, Tatuya Internet Systems Consortium, Inc. FYI, this is an example result for my test box, where resperf reported a maximum throughput of 23858qps: # time target_qps actual_qps responses_per_sec failures_per_sec avg_latency 0.250 104.17 104.00
