Mark Miller commented on SOLR-743:
----------------------------------
bq. Although it is slower (which doesn't surprise me), does it really matter?
Right...of course its going to be slower, but my guess was that it was slower
in a way that compiler/hotspot optimizations, nature of the code, etc, would
make the difference not really matter (its what effective java seemed to
indicate, and since he wrote the code..).
But the results yonik posted...if thats the slowdown, I don't see moving as an
option...and if we were using enums I'd vote for a switch to bitset. Seems like
quite a difference to me (though I still havn't had time to educate myself with
the test code used).
