Faster Ruby Gem installs
Ruby gems install slowly because rdoc and ri documentation are generated as the gems install. Since this is rarely used, why not turn it off? I always check the internet for up-to-date docs anyway, which give me a chance to see if there’s a newer version of the gem out.
To turn these off, modify your ~/.gemrc file and add the line:
gem: --no-rdoc --no-ri
