Boxing and generics with type erasure making it difficult or impossible to reduce the density of references in the heap. Structs and reified generics can give huge performance improvements. Hash tables and complex arithmetic are some examples where I often see F# running 5-20× faster than idiomatic OCaml/Java code.
