zjflike opened a new issue #184: some confusion about bookkeeper performance URL: https://github.com/apache/distributedlog/issues/184 **QUESTION** I have tested two different bookkeeper, which is bookkeeper 4.3.4-TWTTR and the new bookkeeper 4.5.0. I find out bookkeeper 4.5.0 has a worse performance compared with bookkeeper 4.3.4-TWTTR, and here is my test report: in bookkeeper 4.3.4-TWTTR: > "bookkeeper_server.ADD_ENTRY" : { "count" : 3425445, "max" : 7.41E-4, "mean" : 4.579571984435798E-5, "min" : 3.0E-5, "p50" : 4.4000000000000006E-5, "p75" : 4.6E-5, "p95" : 5.254999999999996E-5, "p98" : 5.741999999999996E-5, "p99" : 8.371000000000004E-5, "p999" : 7.353740000000008E-4, "stddev" : 3.2124531013854395E-5, "m15_rate" : 835.1689420800385, "m1_rate" : 648.1885926153338, "m5_rate" : 826.3971430083111, "mean_rate" : 495.75097584866603, "duration_units" : "seconds", "rate_units" : "calls/second" } in bookkeeper 4.5.0: > "bookkeeper_server.ADD_ENTRY" : { "count" : 1989593, "max" : 8.550560000000001E-4, "mean" : 6.543760311284048E-5, "min" : 3.1085000000000005E-5, "p50" : 5.8833000000000004E-5, "p75" : 6.157950000000001E-5, "p95" : 7.241495E-5, "p98" : 9.612595999999987E-5, "p99" : 4.2929724000000005E-4, "p999" : 8.536968280000003E-4, "stddev" : 5.917626043631808E-5, "m15_rate" : 830.11667426358, "m1_rate" : 349.7475662441205, "m5_rate" : 669.5704800826474, "mean_rate" : 178.61990685543887, "duration_units" : "seconds", "rate_units" : "calls/second" } The above results are tested from same config(MSG_SIZE=256, MAX_RATE=40000). Is there anyone meet this question? Or what cause a worse performance?Can someone explain that?
