Sorry - but we probably need *still* more detail! - the definition of
viewfoo is likely to be critical. For instance a simplified variant of
your setup does 200000 inserts in 5s on my PIII tualatin machine:
CREATE TABLE foo1 (x INTEGER);
CREATE VIEW viewfoo AS SELECT * FROM foo1;
CREATE RULE ruleFoo AS ON INSERT TO viewfoo DO INSTEAD
(
INSERT INTO foo1 VALUES (new.x);
)
CREATE OR REPLACE FUNCTION functionFoo() RETURNS VOID AS $$
BEGIN
FOR i in 1..200000 LOOP
INSERT INTO viewfoo (x) VALUES (i);
END LOOP;
END;
$$ LANGUAGE plpgsql;
postgres=# \timing
postgres=# SELECT functionFoo() ;
functionfoo
-------------
(1 row)
Time: 4659.477 ms
postgres=# SELECT count(*) FROM viewfoo;
count
--------
200000
(1 row)
