timing

Timing is a simple library to log call time using perf4j.

Usage

[timing "0.1.2"]

timed

Just wrap forms you want to calculate call time:

(timed :tag
  (look-up-db ...)
  (assemble-data ...))

Note that you have to provide a tag to identify these forms in timing log.

Timing will select a logging provider automatically by looking up your classpath (slf4j, log4j and stderr). Timing doesn't depend on any logging provider at compile time.

timed-fn

Convert a predefined function to a timed one.

(defn count-how-many-people-on-the-earth [req]
  )

(defroute my-website
  (GET "/count" (timed-fn count-how-many-people-on-the-earth)))

defn-timed

Define a function who is born to be timed.

(defn-timed count-how-many-ants-on-the-earth [req]
  )

wrap-timed

There's also a built-in ring middleware to log call time for every request. wrap-timed uses uri as timing tags.
