Readme for bench-1.0.1

[back to package description]

Bench v1.0.1

Think of this as a more powerful alternative to the time command. Use this command-line tool to benchmark a command using Haskell's criterion library.

Key features:

  • Repeated runs
  • Detailed statistical output
  • Gorgeous HTML output (via the --output flag) (Example)
  • Also supports CSV or templated output

Quick Start

First, download the Haskell toolchain, which provides the stack build tool.

You will also need to download git if you haven't done so already.

Then run the following commands from a terminal to build and install the bench tool:

$ git clone https://github.com/Gabriel439/bench.git
$ cd bench
$ stack install

stack install will install bench to ~/.local/bin or something similar. Make sure that the installation directory is on your executable search path before running the following command. stack will remind you to do this if you forget.

$ bench 'sleep 1'  # Don't forget to quote the command line
benchmarking sleep 1
time                 1.003 s    (1.002 s .. 1.003 s)
                     1.000 R²   (1.000 R² .. 1.000 R²)
mean                 1.003 s    (1.003 s .. 1.003 s)
std dev              92.92 μs   (0.0 s .. 101.8 μs)
variance introduced by outliers: 19% (moderately inflated)

$ bench true
benchmarking true
time                 410.3 μs   (382.3 μs .. 443.3 μs)
                     0.974 R²   (0.961 R² .. 0.987 R²)
mean                 420.7 μs   (406.8 μs .. 435.7 μs)
std dev              47.69 μs   (40.09 μs .. 57.91 μs)
variance introduced by outliers: 81% (severely inflated)

All output from the command being benchmarked is discarded

Development Status

Build Status

This is a pretty simple utility which just wraps criterion in a command-line tool, so I don't expect this project to change much. However, only time will tell.
