IseqRailsTools

Since Ruby 2.3, we've had the ability to dump out compiled Ruby bytecode to files to alleviate that process when ruby files are required. This can significantly boost boot times, especially when running with larger Ruby projects. With this gem in your Gemfile, your app can boot up to about 30% faster.

When deploying to production, you can take advantage of the quicker boot times by adding the iseq:all rake task to your deploy script. A simple way to do this is to make iseq:all a prerequisite of assets:precompile, like so: Rake::Task['assets:precompile'].enhance(['iseq:all']).

1. Add iseq_rails_tools to your Gemfile.
2. Run bundle install to download the gem.
3. Add .iseq/ to your .gitignore.

Then when running the console or the server, the compiled files will start to be generated in a new .iseq directory in the root of the repository.

IseqRailsTools adds a couple Rake tasks to your Rails project:

1. iseq:all - Compile iseq files for all files under autoloaded paths
2. iseq:clear - Clear out all compiled iseq files

A lot of the inspiration (as well as some of the code) for this gem came from Koichi Sasada's great work on the yomikomu gem.
