> Enhance ByteBufferUtils.findCommonPrefix to compare 8 bytes each time

> Key: HBASE-28025

> Project: HBase
> Issue Type: Improvement
> Components: Performance
> Affects Versions: 2.5.4
> Reporter: Becker Ewing
> Assignee: Becker Ewing
> Priority: Major
> Fix For: 2.6.0, 2.4.18, 2.5.6, 3.0.0-beta-1

> Currently, the `ByteBufferUtils.findCommonPrefix family of methods compare
> two buffers a single byte at a time. In reviewing the patch for HBASE-28012,
> [~zhangduo] suggested that the ByteBufferUtils.findCommonPrefix methods could
> be enhanced to compare 8 bytes at a time like the
> ByteBufferUtils.compareToUnsafe family of methods already does (which was
> added in HBASE-12345)
