Subject [jira] Commented: (LUCENE-1796) Speed up repeated TokenStream init
Date Mon, 10 Aug 2009 20:08:15 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741523#action_12741523

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?
