Subject [jira] Commented: (LUCENE-1410) PFOR implementation
Date Fri, 02 Apr 2010 19:46:28 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852933#action_12852933

Renaud Delbru commented on LUCENE-1410:
---------------------------------------

Just an update,

I just executed the same benchmark, but instead of executing only 200 queries per run, I have
executed 1000 queries, and it seems that the results of FOR and PFOR are better. Maybe, this
is again an effect of the JIT. 200 queries per run were not enough to see the effect of the
JIT, and therefore FOR and PFOR were penalized.

I'll perform again the full benchmarks with a larger number of random queries, and report
to you the results (hopefully good results).
