Here is one more related question.
It looks like the o.a.l.benchmark.Driver class is supposed to be a generic
driver class that uses the Benchmarker configured in one of those conf/*.xml
files. However, I see StandardBenchmarker.class hard-coded there:
digester.addObjectCreate("benchmark/benchmarker", "class",
StandardBenchmarker.class); <==
digester.addSetProperties("benchmark/benchmarker");
digester.addSetNext("benchmark/benchmarker", "setBenchmarker");
Is this by design? Is there any way for me to get the Driver aware of my
MatcherBenchmarker other than by modifying Driver directly?
Thanks,
Otis

Subject: Benchmarking LUCENE-584 with contrib/benchmark
Hi,
I'm looking at benchmarking Paul's
http://issues.apache.org/jira/browse/LUCENE-584 code.
I'd like to compare either:
HitCollector.collect(doc, score) vs. MatchCollector.collect(doc)
or
IndexSearcher.search(Weight, Filter, HitCollector) vs.
IndexSearcher.match(Query, MatchCollector)
...and see what the performance difference is when one skips scoring. I can
cook up my own benchmark, but I'd rather try using contrib/benchmark, if it can
be used for this purpose. Can it? I browsed around contrib/benchmark looking
for a place where I could plug in calls to IndexSearcher.match(Query,
MatchCollector), and found that the only search calls are in the
StandardBenchmarker class. From what I can tell, I can't really plug in any
other calls in there, can I? It looks like I simply need to write my own
MatcherBenchmarker and implement my own benchmark(File, BenchmarkOptions)
method. Once that's in place, I'd have to run one benchmark with the
StandardBenchmarker and the other one with my MatcherBenchmarker and manually
compare the numbers.
Is that the right approach, or am I missing a shortcut?
Thanks,
Otis
