John Wang commented on LUCENE-2159:
-----------------------------------

Shai:

      You are right, we found this tool useful with testing performance 
implications under index segmentation. I understand having a general 
performance suite to test regression is a good thing. But we found having a 
more focused test for segmentation and merge is important.

> This tool does that. See attached class.
