60% longer is a lot. I'm surprised. I'd try compiling the whole thing both ways with profiling on and see if that reveals anything S | -----Original Message----- | From: haskell-cafe-admin@haskell.org [mailto:haskell-cafe-admin@haskell.org] On Behalf Of David | Roundy | Sent: 30 May 2003 13:06 | To: haskell-cafe@haskell.org | Subject: how to break up a large module? | | I recently spent a couple of hours breaking up a large module (2.5k lines) | into several smaller modules.
