Faster Rails Load Times

Faster load times? (circa 2011)

  • Benchmark with:

        $ time script/rails runner "puts 1"
  • Dropped from 18 to 13s using :require => false judiciously in Gemfile.

  • (outdated with ruby 2.3, I think) Dropped from 13 to 8.5s using patched ruby:

pre-push script: Protects some branches from destructive actions.
#!/usr/bin/env ruby
# NOTE! this is a work in progress. This is not tested or used regularly.
# Ensures we do not call destructive commands on protected branches.
# Called by "git push" after it has checked the remote status,
# but before anything has been pushed.
# If this script exits with a non-zero status nothing will be pushed.
You can’t perform that action at this time.
