Not entirely true; If you want good speed I think it's worth trying to 
code things so all the necessary memory will fit within your cache.  Of 
course this will put a limit on the size of problem you can solve 
without slowing things down a bit.  I'm sure that someone like Warp 
could give you more detailed pointers, although if you're doing this in 
haskell it may not lend itself to this sort of optimization as well as, 
say, C++.
