Re: [Haskell-cafe] ST not strict enough?

2011/11/16 Tristan Ravitch :

Have you tried building the vector using things besides write/ST? It might be a bit faster to use something like Vector.unfoldr or Vector.generateM and ByteString.index to build up a pure Vector. After that you could use Vector.unsafeThaw to convert that pure Vector into an MVector.

I tried unfoldrN and, indeed, the memory usage has gone down. Residency seems to be <45K, regardless of input size; and the productivity is above 90% even for small (128K) inputs. Thanks for your suggestion. -- Jason Dusek ()  ascii ribbon campaign - against html e-mail /\  www.asciiribbon.org   - against proprietary attachments
