Below are the results of the Lucene nightly geo benchmarks based on the master branch as of that point in time.
This test indexes a 60.8M point subset exported from the full (as of 3/7/2016) 3.2B point OpenStreetMaps corpus, including every point inside London, UK, and 2.5% of the remaining points, using three different approaches, and then tests search and sorting performance of various shapes. The London boroughs polygons come from here (33 polygons, average 5.6K vertices).
On each chart, you can click + drag (vertically or horizontally) to zoom in and then shift + drag to move around, and double-click to reset. Hover over an annotation to see known changes. Click on a point to see the exact source git revision that was run.
