> Could you please be so kind as to repeat your tests with psycopg 3.1.4?
Tried with 3.1.4 and it has idle processor usage while waiting for the 8 results, just like psycopg2.
Tried with 3.1.5 and it spikes up to 62% reported CPU usage while waiting for the 8 results, just like the current release.


> Also, did you try only to connect on localhost? Are you able to run the same test with a server running on a different network location?
Have now tried with both a local host, and spreading the connections out over a number of remote servers, and the results are the same for both situations.
