This doesn’t mean they are right for every situation, but when they are, they can greatly enhance performance. Working with arrays in Clojure is surprisingly easy once you get used to it, but there are a few gotchas worth pointing out. Type hints Array operations are only fast if they avoid reflection . Therefore, you really need to make sure you provide appropriate type hints any time you use any array operation. In most cases, turning on the compiler flag *warn-on-reflection* will prevent you from generating slow, reflective code. Microbenchmark In the following sections, I will be referencing lines from the output of this program: (ns t.core (:require [criterium.core :as crit]) (:gen-class)) (set! *warn-on-reflection* true) (set! *unchecked-math* :warn-on-boxed) |
