Github user HeartSaVioR commented on the issue: https://github.com/apache/storm/pull/2203 I have a perf test report to share. Please note that it is rather sharing raw numbers, instead of some analysis. OS: Ubuntu 17.10, 4.13.0-25-generic #29-Ubuntu SMP Mon Jan 8 21:14:41 UTC 2018 CPU: AMD Ryzen 5 1600 3.2Ghz 6 core (with hyper-thread = 12 logical cores) RAM: Samsung DDR4 32G 19200 SSD: Samsung 850 Evo Ran TVL, rate 50000, max spout pending 5000, other parameters are default. The values fluctuate a bit, so it would be better to just get overall trend instead of number to number comparison. > 1.2.0-SNAPSHOT (9fbe283) >> 1st uptime | acked | acked/sec | failed | 99% | 99.9%
