## Class Benchmark

- java.lang.Object
- - org.apache.lucene.benchmark.byTask.Benchmark

-     public class Benchmark
      extends Object

  Run the benchmark algorithm.

  Usage: java Benchmark algorithm-file

  1. Read algorithm.
  2. Run the algorithm.
  Things to be added/fixed in "Benchmarking by tasks":
  1. TODO - report into Excel and/or graphed view.
  2. TODO - perf comparison between Lucene releases over the years.
  3. TODO - perf report adequate to include in Lucene nightly build site? (so we can easily track performance changes.)
  4. TODO - add overall time control for repeated execution (vs. current by-count only).
  5. TODO - query maker that is based on index statistics.
