 * <b>indiscriminately</b> to the methods of the delegate. For example, overriding {@link

    * Add `-prof gc` to the options to check whether the garbage collector runs during a microbenchmarks and skews
   your results. If so, try to force a GC between runs (`-gc true`) but watch out for the caveats.
    * Add `-prof perf` or `-prof perfasm` (both only available on Linux, see Disassembling below) to see hotspots.
    * Add `-prof async` to see hotspots.
* Have your benchmarks peer-reviewed.
