How should I modify it to make it useful on large file? It eats too much memory...
procFile = putStrLn . show . foldl merge [] . ^^^^^

foldl is infamous for building the complete list, before evaluating anything. Did you try foldr or foldl' instead? Also, you may want to make 'merge' more strict; I suspect you build lazy tuples that look like ("word",1+1+1+1+...) and only get evaluated at the end. Using heap profiling will probably give you some hints (well documented in the GHC manual, ask if you get stuck) -kzm -- If I haven't seen further, it is by standing in the footprints of giants
