LUCENE-10145: Speed up byte[] comparisons using VarHandles. (#349)
> Use VarHandles to speedup byte[] comparisons in some cases
> ----------------------------------------------------------
>
> Key: LUCENE-10145
> URL: https://issues.apache.org/jira/browse/LUCENE-10145
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Adrien Grand
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> I noticed that using Long#compareUnsigned on longs read via VarHandles is
> significantly faster than calling compareUnsigned directly. There are cases
> when this could be leveraged easily such as BKDWriter, which often keeps
> comparing 4-bytes or 8-bytes across byte[] arrays.
