Paul Elschot created LUCENE-5416:
------------------------------------
Summary: Performance of a FixedBitSet variant that uses
Long.numberOfTrailingZeros()
Key: LUCENE-5416
URL: https://issues.apache.org/jira/browse/LUCENE-5416
Project: Lucene - Core
Issue Type: Bug
Components: core/search
Affects Versions: 5.0
Reporter: Paul Elschot
Priority: Minor
Fix For: 5.0
On my machine the current byte index used in OpenBitSetIterator is slower than
Long.numberOfTrailingZeros() for advance().
The pull request contains the code for benchmarking this taken from an early
stage of DocBlocksIterator.
In case the benchmark shows improvements on more machines, well, we know what
to do...
