The code is as follows: https://gist.github.com/brfrn169/6a57175d934734b2a2c36652925ffdf6 The results are as follows: Before applying the patch: ``` Benchmark Mode Cnt Score Error Units FSNamesystemBenchmark.benchmark thrpt 25 567.924 ± 3.184 ops/s ``` After applying the patch: ``` Benchmark Mode Cnt Score Error Units FSNamesystemBenchmark.benchmark thrpt 25 573.884 ± 11.171 ops/s ``` It looks like there isn't any performance regression after applying the patch.
