Conclusion: --------------- 1. I think v15 is solving the problem exist with v13 and performance is significantly high compared to base, and relation size is also stable, So IMHO V15 is winner over other solution, what other thinks ?
It seems so, do you have ability to reasonably test with 64 clients? I am mostly wondering if we see the performance going further down or just plateau.
Yes, that makes sense. One more point is that if the reason for v13 giving better performance is extra blocks (which we believe in certain cases can leak till the time Vacuum updates the FSM tree), do you think it makes sense to once test by increasing lockWaiters * 20 limit to may be lockWaiters * 25 or lockWaiters * 30.
