Uwe Schindler commented on LUCENE-1796:
---------------------------------------
Hm, and with the termAtt.clear() instead of clearAttributes? Was the 46-47 with
the clearAttributes call or without? You always have the problem with very
short TokenStreams that are not reused, that the initialization and State
linked-list construction needs some time. In the reused case, it should be
faster with the latest patch or without clearAttributes at all.
Where is the hotSpot? Do you have a figure like before the patch with method
execution times?
