Yeah, Haskell won't give you Rust-like performance. Very few languages will and, except for C, you won't even see them here on the comments.

Haskell can have a reasonable high performance, but if it's you main concern, or if predictability is important, you need a low level language.

Right now I'm using Julia for high performance math heavy modelling with lots of experimentation, and it's great for this purpose. I can get most of C++'s advantages without giving up on flexibility. My code base wouldn't scale to team work / production software though as well as C++.
