+//
+// single thread:
+// java -jar log4j-perf/target/benchmarks.jar ".*Unbox.*" -f 1 -wi 10 -i 15
+//
+// Default config with multiple threads (for example, 4 threads):
+// java -Dlog4j2.enable.threadlocals=true -jar log4j-perf/target/benchmarks.jar ".*Unbox.*" -f 1 -wi 10 -i 15 -t 4
+//
+// Web-app safe config with multiple threads (for example, 4 threads):
+// java -Dlog4j2.enable.threadlocals=false -jar log4j-perf/target/benchmarks.jar ".*Unbox.*" -f 1 -wi 10 -i 15 -t 4
