Not long ago, I threw out 15 000 lines of optimized C in favour of haskell just because of speed; implementing the algorithm I wanted would have been more or less impossible because of the overwhelming complexity. In C I would shoot my toes off by just looking at any memory use; in haskell I can concentrate on coding this much faster algorithm. if you want a 10 times speed up, you wait some time for the hardware technology to make up. if you want a 100 times speed up, you consider your algorithms. ---------------------------------------------------------- Johan 'Mahogny' 'Staalis' Henriksson, mahogny@areta.org Student at Chalmers University of Technology and Gothenburg University Lead Coder at Areta, www.areta.org Engineer and sysadmin at BRK-Tjaenst AB, www.brksweden.se
