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  • (outdated with ruby 2.3, I think) Dropped from 13 to 8.5s using patched ruby:

    $ curl https://raw.github.com/gist/1008945/4edd1e1dcc1f0db52d4816843a9d1e6b60661122/ruby-1.9.2p290.patch > /tmp/require-performance-fix.patch
$ rvm install ruby-1.9.2-p290 --patch /tmp/require-performance-fix.patch -n patch_require
$ cd karma # use `cd .. && cd -` if you are already in the project dir
    • You should see: Using /Users/<you>/.rvm/gems/ruby-1.9.2-p290-patch_require with gemset coed_naked_planning
