Thomas Mueller commented on OAK-1702:
-------------------------------------
I think the most important (only?) thing that needs to be changed is to re-use
the searcher. When searching for terms that have few results (1 result in my
case), I get basically _only_ stack traces like this:

> Key: OAK-1702
> URL: https://issues.apache.org/jira/browse/OAK-1702
> Project: Jackrabbit Oak
> Issue Type: Task
> Components: bench
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Fix For: 1.1

>
> To compare the performance of Full text search between Jackrabbit 2 and Oak a
> benchmark should be added.
> To start with the benchmark would do following
> * Would be based on WikipediaImport benchmark. So it would import the
> wikipedia dump and perform full text query on that
> * Should be able to run on both JR2 and Oak. Need to account for maven setup
> to handle different Lucene version as JR2 uses 3.6.0 and Oak use 4.x
> Later we can add concurrent version
