rbm is a command line tool for doing quick benchmarks of ruby code.

Installing

Recommended

gem install rbm

Edge

git clone https://github.com/samuelkadolp/rbm.git
cd rbm && rake install

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 loop. You can also provide a code fragment to be run before each time each code fragment is run.

rbm --times 100 "sleep 0.01"
rbm --prerun "n = 5" "sleep n"

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
