These questions often depend on how much time you are willing to spend making things fast. OCaml has an extremely predictable performance curve, which is nice when you are writing code that has to run fast. In turn, productivity is good because you don&#x27;t get into situations where you have to rewrite code to make it faster in many cases. Even for brute-force algorithms, it tend to run fast enough that it would work well.<p>Over F#, OCaml provides a module system. This helps programming in the very large.<p>Over Haskell, OCaml provides a module system, and strict evaluation. The latter is a contended point, but proponents of OCaml claim it leads to memory&#x2F;execution predictability. In Haskell (GHC) you often have to turn on optimizations in order to understand how your code will perform in reality, whereas byte-code interpreted OCaml acts just like natively compiled OCaml space wise, but is roughly 10 times faster in execution speed.
