Rubyinside mentioned a blog post on how to speed up gem installation by not installing RI or RDoc.

Is it possible to install a gem and subsequently install documentation at a later date, so you can hack in haste and RTFM at leisure?

If you run gem rdoc --all it will generate documentation for all your gems.

You can also use the following command to generate docs for gems in your bundle:

bundle list | egrep '\*' | sed -e 's/* \(.*\) (.*)/\1/g' | xargs -n 1 gem rdoc

You may need to adapt to your needs and also if bundle changes its output format.
