Simon Willnauer resolved LUCENE-3408. ------------------------------------- Resolution: Fixed > Remove unnecessary memory barriers in DWPT > ------------------------------------------ > > Key: LUCENE-3408 > URL: https://issues.apache.org/jira/browse/LUCENE-3408 > Project: Lucene - Java > Issue Type: Improvement > Components: core/index > Affects Versions: 4.0 > Reporter: Simon Willnauer > Assignee: Simon Willnauer > Priority: Minor > Fix For: 4.0 > > Attachments: LUCENE-3408.patch > > > Currently DWPT still uses AtomicLong to count the bytesUsed. Each write > access issues an implicite memory barrier which is totally unnecessary since > we doing everything single threaded on that level. This might be very minor > but we shouldn't issue unnecessary memory barriers causing processors to lock > their instruction pipeline for no reason. -- This message is automatically generated by JIRA.
