Answer 1

One method to speed up this process is to use the --no-document flag for gem install by editing your ~/.gemrc file to include the following:

gem: --no-document

Alternatively, you can just add it to your gem commands:

gem install --no-document bundler
bundle update --bundler
bundle install --retry=3 --jobs=4
gem install --no-document fastlane

If you find that it's not working then perhaps you have an older version of Ruby and should explore some alternative settings for older versions.

You don't need to make any changes for bundle install because bundler does not install documentation by default.

The documentation is clearly not the most costly step in terms of time, but cumulatively this will add up.
