What exactly is this test?
I think assuming it is a read-only -M prepared pgbench run where data fits in shared buffers. However if you can share exact details, then I can try the similar test.
Crazy that this has such a negative impact. Amit, can you reproduce that?
I will try it.
Alexander, I guess for r/w workload 5364b357 is a benefit on that machine as well?
I also think so. Alexander, if try read-write workload with unlogged tables, then we should see an improvement.
