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 )

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
