Adrien Grand resolved LUCENE-3654. ---------------------------------- Resolution: Implemented Since LUCENE-7966, when using Java 9 or higher, BytesRef comparators will use Arrays#compareUnsigned and Arrays#equals which can compare multiple bytes at once. > Optimize BytesRef comparator to use Unsafe long based comparison (when > possible) > -------------------------------------------------------------------------------- > > Key: LUCENE-3654 > URL: https://issues.apache.org/jira/browse/LUCENE-3654 > Project: Lucene - Core > Issue Type: Improvement > Components: core/index, core/search > Reporter: Shay Banon > Priority: Major > Attachments: LUCENE-3654.patch > > > Inspire by Google Guava UnsignedBytes lexi comparator, that uses unsafe to do > long based comparisons over the bytes instead of one by one (which yields > 2-4x better perf), use similar logic in BytesRef comparator. The code was > adapted to support offset/length. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
