# About Trivial-Benchmark Frequently I want to do a quick benchmark comparison of my functions. ``time`` is nice to get some data, but it's limited to a single run so there isn't really much of a statistical value in it. Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from ``time``, for all other implementations just the REAL- and RUN-TIME data. # How-To We assume that there's a local or global nickname for ``org.shirakumo.trivial-benchmark`` called ``tb``. You can activate the global nickname with ``(org.shirakumo.trivial-benchmark:add-nickname)``. For basic throwaway benchmarking, the ``with-timing`` macro should suffice: :: common lisp (tb:with-timing (1000) (+ 1 1)) :: However, you can also do more complex timing using your own ``timer`` and ``with-sampling``. The former creates a new timer object (with an optional list of metrics to sample) and the latter collects one sample for each metric of the timer for the duration of the body forms. :: common lisp (defvar *timer* (make-instance 'tb:timer)) (tb:with-sampling (*timer*) (+ 1 1)) (tb:with-sampling (*timer*) (expt 10 100)) (tb:report *timer*) (tb:reset *timer*) (tb:report *timer*) ::
