The input list is being read from disk by lazy I/O. With the original implementation, the input file gets read at the same time as the output file is written. But runST returns nothing until the *entire* input has been compressed. So writing to disk doesn't start until the entire file has been slurped up into memory. Anybody have any hints on how to get around this?
I'd recommend using an enumerator/iterator package to read and process the file as a stream of chunks. The assumption here is that you don't need the entire input to provide enough state to begin generating output. -- -KQ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
