Hardy, thanks. That really helps.

No problem. Actually glad to hear that this setup helped. I created it a while back with the intention to create a performance baseline for upcoming work on improving faceting. I am planning to extend it once I start the actual implementation.

I've extended it quite a bit to more mimic how we run queries, and to run multi-threaded.

Cool. If you think that you come up with something which is useful worth sharing, feel free to create a pull request

Good news seems to be that things are okay.

Good news for us indeed. Good luck with the bug hunt.
