Re: Using PGTune - is it a good source for system configuration?

Hi, and thanks for replying.

Yeah, sure, it's not a silver bullet, but the thrust of my question
was: do the community experts consider it reliable enough as a first
approximation?

Your remarks about "better than the generic defaults" reassures me
that this is the case.

This is just my laptop - but I've taken PGTune's recommendations
before for a data loading and it was a real help...

One other question that I forgot to include in my original!

I have a two CPU core (that's why I put 2 for the number of CPUs) but
my processor supports hyperthreading (Intel Core i5, 7th Gen), so
should I really put 4 as the no.

Changing this from 2 to 4 changes the

work_mem from 41943kB to 20971kB and the worker settings from

max_worker_processes = 2
max_parallel_workers_per_gather = 1
max_parallel_workers = 2
max_parallel_maintenance_workers = 1

to

max_worker_processes = 4
max_parallel_workers_per_gather = 2
max_parallel_workers = 4
max_parallel_maintenance_workers = 2

So, which would be the correct Number of CPUs setting given my processor?

TIA and rgs,
