OK, I'm attaching are results from mine runs 5 and 6: - only seqconcurrscans was tested, well because for other workloads io_worker method was not getting load for those workers (only seq scans were offloaded) - checksums were disabled, because IMHO that would be unfair comparision (AFAIR there are offloaded) - those optimizations for 0008 "optimized (numa=on, bal=on)" easily beat "patched (numa=on, bal=on)" and seem to be crucial. We get like 1.2x-1.4x across every io_method, but only with 0008. - even when then doing just those logical fully cached reads from fully VFS cached case, io_urings shines (I've added raw TPS number to show this, compare across tables e.g. io_uring vs sync 13.378/8.993=1.487x for io_uring with NUMA, but for master's for io_uring:sync it was just 8.79/7.389 = 1.189x without NUMA); seems like io_uring is more lightweight to show more benefits of remote memory latencies - there's some more juice to get out of the balancer for 0-reuse workloads (but IMHO it's pointless to squeeze more, it's hard already) - I was probably wrong when expecting that io_worker's worker processes/queues should get NUMA affinity. They don't need to be apparently for me to see benefits (maybe they could be and it would even better, but meh). So with ruling io_method impact (I speculated earlier that his could be it), this means that you were either hitting lack of opimizations needed from 0008 or were impacted by lack of drop_caches before the runs > Maybe You could run those run*.sh with master vs inst-patchset/optimized? > (I'm not sure, maybe there's even different factor at play too...) This is seems to be crucial now, to double confirm the results / loaded-tested on your hw with 0008. (but that hardware really needs to have effective latency difference between at least 2 NUMA nodes -- Intel's mlc is good for this); maybe also tweak those 125% inside 0008 to some other values, I've got 4 nodes, so 100/4=25%) > 3.

And this one is still potentially on the table as nice thing to have. -J.Title: Extended IO-Method Metrics Dashboard
