[Haskell-cafe] Vedr: To my boss: The code is cool, but it is about 100 times slower than the old one...

The program seems to take around 6 seconds on my linux-box, while the c version goes for 0.06 sekcond.

That is really some regression bug :-)

Anyone with a more recent version thatn 7.4.1?

Felix

Ack, it seems like you're running into one of these bugs (all now
fixed, but I don't know in which GHC version):
