Gave a shot to the new Bundler 1.4.0RC1 during the weekend and found out it now supports gem installation in parallel. To invoke you need to pass
--jobs parameter with number of threads you want it to run – for me the best performance was achieved by specifying the number physical CPU cores.
I've tested on the AppFab app. In my case (CPU with 2-core i7 with HT) the speedup was 50%. I've also tried with a number greater than the number of physical cores but the performance was 15%-20% worse.
alias bi="bundle install --path vendor/bundle --binstubs=vendor/bundle/bin"
Now no more
bundle exec before any rake, cap, spec or anything else :)
Go to lib folder and use bundler to generate main files for a gem:
$ bundle gem test_gem create test_gem/Gemfile create test_gem/Rakefile create test_gem/LICENSE create test_gem/README.md create test_gem/.gitignore create test_gem/test_gem.gemspec create test_gem/lib/test_gem.rb create test_gem/lib/test_gem/version.rb Initializating git repo in /path/to/webapp/HouseTrip-Web-App/lib/test_gem
cd in to created directory
$ cd test_gem/
