    Description

      Is there some workload where our timSort is better than the JDK one? Should we just remove ours if its slower?

      Not that its a great test, but i switched Polygon2D edge sorting (just the one where it says "sort the edges then build a balanced tree from them") from Arrays.sort to ArrayUtil.timSort and was surprised when performance was much slower for an enormous polygon (http://people.apache.org/~mikemccand/geobench/cleveland.poly.txt.gz)
