Based on the little bit of stuff I've done, I think I'd characterize it this way: C++ will be maybe twice as fast as Haskell. Maybe a little more, maybe a little less, depending on a lot of details. For heavy computation, Python will be a couple orders of magnitude slower than both.
To be fair, Python offloads its heavy lifting to C libraries - NumPy and SciPy run at very close to full C speed on large datasets. This is also how Matlab works. Unladen Swallow is an upcoming JIT compiler for Python. Where Haskell shines for computation is when you can leverage lazy evaluation. Cheers, G
