The .gemrc file can specify default options for the 'gem' executable, and since I haven't ever looked up ri or rdoc on my local system, I decided to turn these off by default. I've been adding the '--no-ri' and '--no-rdoc' flags for a while, but my laziness just got the better of me.
Turning of the RI and Rdoc documentation speeds up gem installs. Here, installing capistrano without docs takes about 11 seconds, whereas installing the documenation more than doubles the time to about 24 seconds.
CODE:
-
nicks-computer-3:snap nick$ time sudo gem install capistrano --no-ri --no-rdoc
-
Successfully installed capistrano-2.5.10
-
1 gem installed
-
-
real 0m11.480s
-
user 0m7.262s
-
sys 0m0.374s
-
nicks-computer-3:snap nick$ time sudo gem install capistrano --ri --rdoc
-
Successfully installed capistrano-2.5.10
-

If you want to turn off the documentation options, add this line to your ~/.gemrc file:
CODE:
-
gem: --no-ri --no-rdoc
So that it looks something like this:
CODE:
-
nicks-computer-3:snap nick$ cat ~/.gemrc
