> Replace junit-benchmarks with JMH
> ---------------------------------
>
> Key: TINKERPOP-1016
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1016
> Project: TinkerPop
> Issue Type: Improvement
> Components: test-suite
> Affects Versions: 3.1.0-incubating
> Reporter: Ted Wilmes
> Assignee: Ted Wilmes
> Priority: Minor
>
> Replace junit-benchmark with JMH. This includes the following tasks:
> * Evaluate which existing benchmarks should be kept and port them to JMH.
> * Add an initial JMH benchmark for TINKERPOP-957
> * See if we can trigger perf tests with the same scheme that is currently
> used {noformat}mvn verify -DskipPerformanceTests=true/false{noformat}
> * Write developer docs that outline our initial performance testing approach.
