>                 URL: https://issues.apache.org/jira/browse/HADOOP-15124
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: common
>    Affects Versions: 2.9.0, 2.8.3, 2.7.5, 3.0.0, 3.1.0
>            Reporter: Igor Dvorzhak
>            Assignee: Igor Dvorzhak
>            Priority: Major
>              Labels: common, filesystem, fs, pull-request-available, 
> statistics
>         Attachments: HADOOP-15124-branch-3.2.001.patch, 
> HADOOP-15124-branch-3.2.002.patch, HADOOP-15124.001.patch

>          Time Spent: 1h
>  Remaining Estimate: 0h
>
> While profiling 1TB TeraGen job on Hadoop 2.8.2 cluster (Google Dataproc, 2 
> workers, GCS connector) I saw that FileSystem.Statistics code paths Wall time 
> is 5.58% and CPU time is 26.5% of total execution time.
> After switching FileSystem.Statistics implementation to LongAdder, consumed 
> Wall time decreased to 0.006% and CPU time to 0.104% of total execution time.
> Total job runtime decreased from 66 mins to 61 mins.
> These results are not conclusive, because I didn't benchmark multiple times 
> to average results, but regardless of performance gains switching to 
> LongAdder simplifies code and reduces its complexity.
