Set of JMH-benchmarks to tests alternatives for ThreadLocal

This is a set of JMH-benchmarks to test various types of alternatives for ThreadLocal within a web-application. These alternatives are mainly intended for very quick use of slow-to-create objects like NumberFormat.

If you want to test it yourself, clone this repository and use maven to prepare your environment. mvn install should do the trick. Note: some of the code requires Java 1.8.

Afterwards you can run java -jar target/benchmarks.jar -l to see all the benchmarks. For a 'quick' run, use java -jar target/benchmarks.jar -f1 which will run all benchmarks once and create a nice summary at the end.

The benchmarks will take several minutes (they take 10 seconds per benchmark, with 5 benchmarks per class).

If you want to test your own implementation, just create a subclass of AbstractMultiThreadedFormatBench and run mvn clean install. To actually run just your benchmark use java -jar target/benchmarks.jar -f1 UniqueuPartOfYourBenchmark (use -l to see which ones are matched).

See the JMH website for more information. And Maven if you need help installing that.
