JMH benchmark for SimpleLruCache
See [1] for JMH documentation and [2] how to use JMH in Eclipse. The benchmarks pom currently cannot use the JGit parent pom due to an ecj bug [3] regarding annotation processing. Hence for now do not inherit from the JGit parent pom and copy the compiler plugin configuration for javac from the parent pom. After running the Maven build the benchmark can be run using Maven: $ java -jar org.eclipse.jgit.benchmarks/target/benchmarks.jar or in Eclipse by running the main method of the SimpleLruCacheBenchmark class.
