I am not sure whether I am doing the correct benchmarking way. I have the following table ; CREATE TABLE measurement_type ( measurement_type_id bigserial NOT NULL, measurement_type_name text NOT NULL, CONSTRAINT pk_measurement_type_id PRIMARY KEY (measurement_type_id), CONSTRAINT measurement_type_measurement_type_name_key UNIQUE (measurement_type_name) ) I make the following single write operation through pgAdmin : INSERT INTO measurement_type ( measurement_type_name ) VALUES('Width'); It takes 16ms to write a single row according to "Query Editor" (bottom right corner) Am I doing the correct way to benchmarking? I am not sure whether this is expected performance? For me, I am expecting the time measurement is in nano seconds :p Thanks and Regards Yan Cheng CHEOK -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
