rbm
rbm is a command line tool for doing quick benchmarks of ruby code.
Description
rbm lets you benchmark varies code fragments by running them a specified number of times along with code fragments before
and after all of the fragments or an individual fragment. See rbm --help for more information.
Installation
Install it yourself as:
$ gem install rbm
Usage
Using rbm is quite simple. Just pass in each code fragment you want to test as a separate argument.
rbm "sleep 1" "sleep 5"
You can specify the number of times to run each code fragment. You can also provide a code fragment to be run before all code fragments or before a code fragment.
rbm --times 1000 "5 / 5"
rbm --times 1000 --init "n = 5" "n / 5"
rbm --times 1000 --init "n = 5" --pre "m = 5" "n / m"
You may provide a name to each code fragment to be displayed on the benchmark.
rbm --name "sleep for 5" "sleep 5" --name "sleep for 2" "sleep 2"
You can see the full usage statement at any time with rbm --help
Usage: rbm [options] [--name name] [--pre code] code [[--name name] [--pre code] code...]
