Benchmark of geospatial polygon indexes

JMH is used to compute the benchmarks

Currently, four libraries are included in the benchmark:

1. Geotools

2. Lucene

3. MongoDB

4. PostGIS

Parameters

Include "-prof gc" for Memory performance

The benchmarks test both point and polygon intersection and vary

• Number of indexed polygons

Results

On Geofabrik OSM England landuse data, querying with 10,000 random points/polygons.
