// ============================== HOW TO RUN THIS TEST: ====================================
//
// single thread:
// java -jar log4j-perf/target/benchmarks.jar ".*MemoryHandlerJULBenchmark.*" -f 1 -wi 10 -i 20
//
// multiple threads (for example, 4 threads):
// java -jar log4j-perf/target/benchmarks.jar ".*MemoryHandlerJULBenchmark.*" -f 1 -wi 10 -i 20 -t 4 -si true
//
// Usage help:
// java -jar log4j-perf/target/benchmarks.jar -help
