    Description

      From rough experience, I think the current default of 3 is too large. I think we get the most bang for the buck going from 0 to 1.

      I think this will especially impact optimize on an index with many segments – in this case the MergePolicy happily exposes concurrency (multiple pending merges), and CMS will happily launch 3 threads to carry that out.
