This open source software benchmarks the queries per second of an Apache Lucene index. It is an Java implementation and uses MultiFieldQueryParser to form a query. It uses currentTimeMillis to calculate the number of queries within one second. The query keyword relies on a generated randomUUID. This version is bundled with lucene-core-3.2.0.jar for the Lucene library. Below is the output from a benchmark test so far:

java -jar benchLucene.jar /data/doovel/ html

2 Queries per second (1.041 seconds)
10 Queries per second (1.0299999999999998 seconds)
13 Queries per second (1.0210000000000001 seconds)
14 Queries per second (1.0610000000000002 seconds)
14 Queries per second (1.023 seconds)
13 Queries per second (1.077 seconds)
14 Queries per second (1.0090000000000001 seconds)
14 Queries per second (1.0359999999999998 seconds)
15 Queries per second (1.04 seconds)

In the future we hope to have graphs which has been tested in a non-released version of the tool but it is not ready for release. Below is a screenshot of that portion of the tool which will be released in the future:
