While working on
OAK-8141 I noticed the benchmark numbers for GetDeepNodeTest on Oak-Composite-Store are rather low compared to Oak-Segment-Tar.
In an offline conversation Tomek Rękawek mentioned the overhead shouldn't be that big because the implementation should switch to the non-composite implementation as soon as the read operation traverses into the global/writable node store. It seems however, this is not the case when running GetDeepNodeTest. So, this may well be a bug and not an improvement, as filed at the moment.
