Changing to a higher rate CPU would be more helpful if you run less than 32 queries at a time.

hi, recently i change the hardware of my database 32 cores up to 64 cores and 128GB Ram, but the performance is the same.  Perhaps i have to change any parameter in the postgresql.conf?.


PostgreSQL does not (yet) automatically parallelize queries.

Unless you have more than 32 queries trying to run at the same time, increasing the number of cores from 32 to 64 is unlikely to be useful.

Cheers,

Jeff
