do $$
declare x int ;
begin
for i in 1..1000000
loop
let ooo = i;
end loop;
end;
$$;
variant 1 .. 1500 ms
variant 2 with PLpgSQL support .. 140 ms
variant 2 without PLpgSQL support 9000 ms
--------------------------------------------------
That's impressive! But 1 million times of variable assignment took only 140
ms? It's that one assignment took only 140 nanosecond, which is near one DRAM
access? Can PL/pgSQL processing be really so fast?
