Hi All,

I've run the following program and found it to be extremely slow. Why?
Does it mean that streams are worth using only when they are built from
input text channels, and in all other cases they are just a waste of
time?

Alexander

open Printf

let gen_stream n =
  let rec gs i n =
    if i = n then [< 'n >] else [< 'i; (gs (i+1) n) >]
  in
  gs 1 n

let rec stupid_loop n s =
  if n > 0 then begin
    if n mod 1000 = 0 then (print_char('.'); flush stdout);
    let i = Stream.next s in
    if i <> n then raise (Failure "they don't match");
    stupid_loop (n+1) s
  end
  else 0;;

let _ =
  stupid_loop 1 (gen_stream 100000);;
