This seems to be normal, ri is searching a larger file set now.

I believe ri scans each .yml file for matching information. An index
would probably be a nice way to speed it up.

That would be using a sledgehammer to solve a problem you could fix
with a tap of your palm.

ri "search" is quite dumb. It only matches against classes, modules
and methods.

(Also, ri_cache.rb already exists. It probably only needs to be
serialized and updated when new documentation arrives (from gems).)

Or use emacs, ri-emacs just reads the information once.
