> zio has excellent performance, featuring a hand-optimized, low-level interpreter that achieves zero allocations for right-associated binds, and minimal allocations for left-associated binds. > The benchmarks [1] project may be used to compare IO with other effect monads, including Future (which is not an effect monad but is included for reference), Monix Task, and Cats IO. > As of the time of this writing, IO is significantly faster than or at least comparable to all other purely functional solutions. https://zio.dev/docs/overview/overview_performance https://zio.dev/docs/overview/overview_performance [1] https://github.com/zio/zio/tree/master/benchmarks https://github.com/zio/zio/tree/master/benchmarks
