I disabled it because it was causing problems in the generated code
after the new STI changes, possibly because of the index ordering issue
we discussed. If you can turn it back on and get it all passing, it
would be nice to have again. I believe it helped a little bit...but not
a massive amount.
Just in regards to help it provide[sd]...
From what I remember once hotspot kicked in, it made little difference
whether it was there or not. However, before hotspot kicks in it is a
measurable improvement (and it could be larger now since some overhead
in JRuby has made all boats rise).
