This may be related to this other issue: https://github.com/apache/lucene/issues/11767

Start by comparing the two attached polygon files, FE-24544446.txt and ORG-24132378.txt, and read the related issue 11767. Reproduce their indexing times and trace the indexing path to identify why the smaller polygon is slower; done means the cause and a verified correction are established.
