Hi there, I am investigating possible throughput with PostgreSQL 14.4 on an ARM i.MX6 Quad CPU (NXP sabre board). Testing with a simple python script (running on the same CPU), I get ~1000 request/s. import psycopg as pg conn = pg.connect('dbname=test') conn.autocommit = True cur = conn.cursor() while True: cur.execute("call dummy_call(%s,%s,%s, ARRAY[%s, %s, %s]::real[]);", (1,2,3, 4.0, 5.0, 6.0), binary=True ) where the called procedure is basically a no-op: CREATE OR REPLACE PROCEDURE dummy_call( in arg1 int, in arg2 int, in arg3 int, in arg4 double precision[]) AS $$ BEGIN END $$ LANGUAGE plpgsql; This seems to be a quite low number of requests/s, given that there are no changes to the database. Looking for suggestions what could cause this poor performance and where to start investigations. Thanks,
