Robert Muir commented on LUCENE-2023:
-------------------------------------
well, i'm more than willing to do the backport, if will be used.
for now, maybe someone can take a look and double-check the patch for trunk,
smartcn is always dangerous territory. :)
(for the record the big bottleneck was the hashmap usage in these graphs, its
rather silly since its indexed by int, you know the number of values up front,
etc)
