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 Priority: Minor Fix For: 4.0 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.
