Yura, thank you for your benchmarks!
We already knew that patch can save the day on pathological workloads, now we have a proof of this.
Also there's the evidence that user can blindly increase size of SLRU if they want (with the second patch). So there's
noneed for hard explanations on how to tune the buffers size.
Thomas, do you still have any doubts? Or is it certain that SLRU will be replaced by any better subsystem in 16?
