Tufte allows you to easily monitor the ongoing performance of your Clojure and ClojureScript applications in production and other environments.
It provides sensible application-level metrics, and gives them to you as Clojure data that can be easily analyzed programatically.

;; Request to send `profile` stats to `println`:
(tufte/add-basic-println-handler! {})
;;; Define a couple dummy fns to simulate doing some expensive work
(defn get-x [] (Thread/sleep 500) "x val")
(defn get-y [] (Thread/sleep (rand-int 1000)) "y val")
;; Let's check how these fns perform:
(profile ; Profile any `p` forms called during body execution
{} ; Profiling options; we'll use the defaults for now
(dotimes [_ 5]
(p :get-x (get-x))
(p :get-y (get-y))))
