This PR provides a JMH benchmark that demonstrated performance issues with accessing component metadata. The benchmark is executed by running the main method in `ComponentBenchmarks`. It should be run 2-3 times to get reliable results. On my machine the results are: > Run complete. Total time: 00:02:44 > > Benchmark Mode Cnt Score Error Units > ComponentBenchmarks.detachComponentWithFlags thrpt 20 **12295,363** ± 71,343 ops/s > ComponentBenchmarks.detachComponentWithMetaData thrpt 20 **8855,321** ± 34,743 ops/s I couldn't get to the root cause of the performance issues but the PR suggests a possible workaround: Using request-level flags that are checked before accessing component metadata. https://issues.apache.org/jira/browse/WICKET-6771 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
