Thank you everyone. I measuring my program using time unix an I going to try to
use the GHC profiling too.

Hi Tays,
If I understood correctly, if your compiler generates Haskell code, then later
on you should compile this code (with GHC, for example) and running it implies
a main function that is of the tipe IO() (i.e. IO Monad).
What you can do is to add (it could be, for example, in debugging mode in your
compiler) the code i paste below at the beginning and in the end of your main
function.
Well, I don't know exactly if this answers your question. If it doesn't, my
apologies.
Cheers
Cristian
import System.Time
import Text.Printf
{
; timeStart <- getClockTime
... your process
; timeEnd <- getClockTime
; let diff = (normalizeTimeDiff (diffClockTimes timeEnd timeStart))
; print ((((fromIntegral(tdPicosec diff))/(10^12))) + (fromIntegral((tdSec
diff) + (60 * (tdMin diff)) + (3600 * (tdHour diff)))))
; return ()
}

GHC has profiling support.
(By the way, many mail servers these days discard mail with no subject.)
I've seen a number of papers comparing the speed of Haskell code to code of
other functional languages; there is a periodic "shoot out" with ocaml.
Some probably have comparisons with imperative languages, and, even if they do
not, the methodology should help you.
