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

[Ivan Salazar]

I see.

I read some chapters from Purely Functional Data Structures when I was in
college in order to understand some tree algorithms, but not the whole book.
Do you think that could help me to understand performance problems with
code (poorly) written in Haskell?
