Re: benchmark drop for PrimaryKey

[Michael Sokolov]

OK thanks. I guess this benchmark must be run on a large-enough index that
it doesn't fit entirely in RAM already anyway? When I ran it locally using
the vanilla benchmark instructions, I believe the generated index was quite
small (wikimedium10k).  At any rate, I don't have any specific use case
yet, just thinking about some possibilities related to primary key lookup
and came across this anomaly. Perhaps at least it deserves an annotation on
the benchmark graph.
