[jira] [Created] (LUCENE-7268) Remove ArrayUtil.timSort?

Robert Muir created LUCENE-7268:
-----------------------------------

             Summary: Remove ArrayUtil.timSort?
                 Key: LUCENE-7268
                 URL: https://issues.apache.org/jira/browse/LUCENE-7268
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Robert Muir


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)
