A benchmark comparing the performance of different free monad implementations. The benchmark simulates the state monad using various flavors of free monads, and compares them to the standard State monad from transformers. See also: Two failed attempts at extensible effects. Note that this is not a comparison of extensible effects system. Free monads may be used to implement an extensible effect system. Under most implementations, extensible effects introduce an even bigger overhead (dispatching upon the effect requests); this overhead is not present in this benchmark. However, if your free monad is slow (which it probably is, as this benchmark shows), any effect system based on it won't be fast.
