I have been working on some tests for improving the performance in
case of bulk INSERTs for our patch. So far, I think it has some
relation to the visibility map optimization, which our patch seems to
be affecting.

Some more testing is in place, which has been delayed due to me being
wound up in other projects. Now that they are complete, I will resume
testing next week or so.
