Re: How to reduce latency with fast short queries in Postgresql 15.3 on a NUMA server

Thanks for your reply, Ken.

With such a big server I was convinced that we should see a boost everywhere, but after spending so much time tweaking and looking at so many parameters on Linux, Postgresql and our current setup, I started to think that maybe that latency was intrinsic to the hardware and therefore inevitable. So after all, the CPU clock speed still counts these days! I think we're many just looking at the number of CPU cores and forgetting that the clock speed is still relevant for many tasks.

I guess those simple short queries are very sensible to the hardware specs and there is no room for improving as much as the heavy queries in recent versions of Postgres, as I have seen in my tests.
