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.
