Not really. Haskell is basically used as a compiler from a DSL to C. Compilers running on general purpose systems are much less sensitive to timing and memory use than embedded systems and kernel drivers, so it isn't that big of a deal. The generated C code is the only thing that executes on the target device so you get the same performance that you would expect from C code.
