Subject [jira] Commented: (LUCENE-675) Lucene benchmark: objective performance test for Lucene

Doron Cohen commented on LUCENE-675:
------------------------------------

Oops... I had the impression that compiling with compliance level 1.4 is sufficient to prevent
this, but guess I need to read again what that compliance level setting guarantees exactly.


Anyhow there are a 3 things that require 1.5:
 - Boolean.parseBoolean() --> Boolean.valueOf().booleanValue()
 - String.contains() --> indexOf()
 - Class.getSimpleName() --> ?

Modifying Class.getSimpleName() to Class.getName() would not be very nice - queries prints
and task names prints would be quite ugly. To fix that I added a method simpleName(Class)
to byTask.util.Format. I am attaching an updated patch - byTask.jre1.4.patch.txt - that includes
this method and removes the Java 1.5  dependency.

Thanks for catching this!
Doron

> We need an objective way to measure the performance of Lucene, both indexing and querying,
on a known corpus. This issue is intended to collect comments and patches implementing a suite
of such benchmarking tests.
> Regarding the corpus: one of the widely used and freely available corpora is the original
Reuters collection, available from http://www-2.cs.cmu.edu/afs/cs.cmu.edu/project/theo-20/www/data/news20.tar.gz
or http://people.csail.mit.edu/u/j/jrennie/public_html/20Newsgroups/20news-18828.tar.gz. I
propose to use this corpus as a base for benchmarks. The benchmarking suite could automatically
retrieve it from known locations, and cache it locally.
