Haskell

I really really like Haskell.
Haskell is life.
Haskell is love.

Ok, a question...

Just started learning Haskell. Really beginner stuff just now.. But I see the preferred data container is a list? Really? Isn't that slow as fuck? It doesn't work well with CPU cache and takes memory overhead.

Or does the GHC optimize lists to something that is sequentally in memory (like C array)? Or is there some array-type that I should use when I wanted performance? Please tell me that it doesn't really use linked lists everywhere. I really would like to learn this language!
