> Improve segment deserialization performance

> Key: OAK-4923
> URL: https://issues.apache.org/jira/browse/OAK-4923
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-tar

> The methods {{readReferencedSegments}} and {{readRecordNumberOffsets}} in
> {{Segment}} compute the returned data every time they are called. While this
> is a very clean implementation, this might force unexpected I/O operations,
> since the "buffer" the data is read from usually is a memory-mapped file.
