Halcyon shootout

Halcyon is a system for installing apps and development tools, including and .

These examples are intended to compare build times and sizes across most Haskell web frameworks.

Each example app can be installed in one command on most recent Linux distributions, including CentOS 7, Debian 7, Fedora 20, and Ubuntu 14.04.

Additionally, each example app can be deployed in one click to or .

Results

Comments

The test simulates installing each example for the first time, by forcing Halcyon to rebuild the sandbox and the app from scratch. GHC and Cabal are restored from local cache.

The times given are mean [low, high], calculated across 10 test runs. Each test run consists of building all example apps on an 8 GB DigitalOcean droplet, running Ubuntu 14.04.

The raw results are available as a . To reproduce the results, use the :

$ halcyon/bin/test shootout --bench
...
hello-yesod,10,521,535,537,251MB,25MB

The output of the test script includes:

  • App name
  • GHC and Cabal restore time
  • Sandbox build time
  • App build time
  • App install time
  • Sandbox size
  • App size
