Subject [jira] Commented: (LUCENE-1410) PFOR implementation
Date Sat, 11 Oct 2008 19:17:44 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638788#action_12638788
] 

Paul Elschot commented on LUCENE-1410:
--------------------------------------

The strange behaviour at 9 bits I reported earlier was due to a mistake in the test data.
It contained only 31 integers (124 bytes, see posted listing), so the unrolled loop would
never be called.

And another point to be done:
- change the decompression code generator to use an array get() from the buffer for 6 or more
frame bits (see the Java 1/2 performance number numbers listed above.)
