It's not a particularly intuitive thing to search for - I found that ticket 
because I knew the topic precisely, and I had seen that ticket before :-).

I created a pull request that updates both Ruby and RubyGems to the latest 
current versions. This also relates to CHEF-2871, which was specific about 
updating to Ruby 1.9.3.

You may see some improvement by simply updating the RubyGems version on a 
system. You can do that with this:

% sudo /opt/chef/embedded/bin/gem update --system

To illustrate that this may positively affect the performance on its own, an 
isolated example (my 2 core, 8G Ubuntu 12.04 system):

% /opt/chef/embedded/bin/gem --version
1.8.12

% time chef-client --help
real    0m13.034s
user    0m11.881s
sys     0m0.408s

% sudo /opt/chef/embedded/bin/gem update --system
...RubyGems 1.8.24 installed...

% /opt/chef/embedded/bin/gem --version
1.8.24

% time chef-client --help
real    0m2.286s
user    0m1.912s
sys     0m0.296s
