Hi,

I'm afraid I don't have many more details.  This was just a comment
that one of our performance guys sent to me a while back.  I haven't
had a chance to investigate his claims or look into what's going on.
I'll do some tests of my own, and if I can recreate a performance
problem based on rgrp size, I'll open a bugzilla record and analyze
what's going on.
