使用JMH基准测试，两种场景:平均耗时，每秒吞吐， 先预热三轮，结合MQ的世纪场景，被求余的数字不会很大，因此设置最小边界是0，最大20480 结果如下: 吞吐还有耗时的提升大概都在2%左右 thrpt: Benchmark (number) Mode Cnt Score Error Units ModVsBitmaskBenchmarkT.bitwise 0 thrpt 4 585542159.635 ± 4617347.105 ops/s ModVsBitmaskBenchmarkT.bitwise 1000 thrpt 4 584290537.081 ± 16650492.968 ops/s ModVsBitmaskBenchmarkT.bitwise 1024 thrpt 4 584381389.631 ± 5641034.048 ops/s ModVsBitmaskBenchmarkT.bitwise 2000 thrpt 4 584370743.001 ± 5346549.000 ops/s ModVsBitmaskBenchmarkT.bitwise 2048 thrpt 4 584875587.741 ± 2605739.696 ops/s ModVsBitmaskBenchmarkT.bitwise 4000 thrpt 4 585558087.640 ± 5470804.999 ops/s ModVsBitmaskBenchmarkT.bitwise 4096 thrpt 4 584200651.599 ± 12188292.420 ops/s ModVsBitmaskBenchmarkT.bitwise 10000 thrpt 4 584816113.774 ± 11292858.085 ops/s ModVsBitmaskBenchmarkT.bitwise 10240 thrpt 4 585215359.048 ± 5118577.383 ops/s ModVsBitmaskBenchmarkT.bitwise 20000 thrpt 4 583738725.485 ± 9722227.841 ops/s ModVsBitmaskBenchmarkT.bitwise 20480 thrpt 4 584743944.006 ± 7697864.815 ops/s ModVsBitmaskBenchmarkT.mod 0 thrpt 4 575176030.964 ± 32486341.103 ops/s ModVsBitmaskBenchmarkT.mod 1000 thrpt 4 574770730.766 ± 25603862.399 ops/s ModVsBitmaskBenchmarkT.mod 1024 thrpt 4 572824030.325 ± 10800376.130 ops/s ModVsBitmaskBenchmarkT.mod 2000 thrpt 4 578344039.587 ± 4655626.485 ops/s ModVsBitmaskBenchmarkT.mod 2048 thrpt 4 577338763.882 ± 9739121.340 ops/s ModVsBitmaskBenchmarkT.mod 4000 thrpt 4 578568934.054 ± 7858263.877 ops/s ModVsBitmaskBenchmarkT.mod 4096 thrpt 4 577444347.683 ± 11004118.322 ops/s ModVsBitmaskBenchmarkT.mod 10000 thrpt 4 578132939.319 ± 6522374.391 ops/s ModVsBitmaskBenchmarkT.mod 10240 thrpt 4 576044853.107 ± 13600487.456 ops/s ModVsBitmaskBenchmarkT.mod 20000 thrpt 4 574045434.464 ± 8018753.080 ops/s ModVsBitmaskBenchmarkT.mod 20480 thrpt 4 576263325.180 ± 7363493.385 ops/s avgt: Benchmark (number) Mode Cnt Score Error Units ModVsBitmaskBenchmark.bitwise 0 avgt 4 1.713 ± 0.016 ns/op ModVsBitmaskBenchmark.bitwise 1000 avgt 4 1.711 ± 0.015 ns/op ModVsBitmaskBenchmark.bitwise 1024 avgt 4 1.713 ± 0.011 ns/op ModVsBitmaskBenchmark.bitwise 2000 avgt 4 1.713 ± 0.013 ns/op ModVsBitmaskBenchmark.bitwise 2048 avgt 4 1.708 ± 0.020 ns/op ModVsBitmaskBenchmark.bitwise 4000 avgt 4 1.714 ± 0.039 ns/op ModVsBitmaskBenchmark.bitwise 4096 avgt 4 1.706 ± 0.014 ns/op ModVsBitmaskBenchmark.bitwise 10000 avgt 4 1.710 ± 0.016 ns/op ModVsBitmaskBenchmark.bitwise 10240 avgt 4 1.709 ± 0.004 ns/op ModVsBitmaskBenchmark.bitwise 20000 avgt 4 1.708 ± 0.012 ns/op ModVsBitmaskBenchmark.bitwise 204800 avgt 4 1.713 ± 0.039 ns/op ModVsBitmaskBenchmark.mod 0 avgt 4 1.736 ± 0.028 ns/op ModVsBitmaskBenchmark.mod 1000 avgt 4 1.737 ± 0.017 ns/op ModVsBitmaskBenchmark.mod 1024 avgt 4 1.757 ± 0.064 ns/op ModVsBitmaskBenchmark.mod 2000 avgt 4 1.751 ± 0.120 ns/op ModVsBitmaskBenchmark.mod 2048 avgt 4 1.730 ± 0.022 ns/op ModVsBitmaskBenchmark.mod 4000 avgt 4 1.739 ± 0.160 ns/op ModVsBitmaskBenchmark.mod 4096 avgt 4 1.750 ± 0.035 ns/op ModVsBitmaskBenchmark.mod 10000 avgt 4 1.746 ± 0.011 ns/op ModVsBitmaskBenchmark.mod 10240 avgt 4 1.727 ± 0.026 ns/op ModVsBitmaskBenchmark.mod 20000 avgt 4 1.723 ± 0.008 ns/op ModVsBitmaskBenchmark.mod 204800 avgt 4 1.747 ± 0.066 ns/op -- This is an automated message from the Apache Git Service.
