Looks like this already filed as a bug here:
[http://tickets.opscode.com/browse/CHEF-3295](http://tickets.opscode.com/browse/CHEF-3295). Thanks for pointing that out
and I guess I should have searched JIRA first. 馃檪

Yes, I can verify this. I also confirmed it was Ruby 1.9.2 by switching
out to 1.9.3. For me it wasn't a big deal so I just decided to wait until
Ruby gets bumped..

Hi,
I confirm that with ruby 1.9.2 (from Omnibus or not) chef-client launch
times are 20 times higher (from 20 to 30 seconds on a typical ubuntu 12.04
m1.small on EC2).
Solved by migrating to ruby 1.9.3 where needed, and I'll stay with Ruby
1.8.7 where I can (launch times usually under 2 seconds).
Cheers,
Stef

How do you update the ruby for an Omnibus installed chef-client?

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

Wow, that did it. Updated from rubygems 1.8.12 to 1.8.24 and running
chef-client -h went from 10.1s to 1.6s! 馃檪

Another data point: this speeds up even ruby 1.9.3 tremendously.
On a (rather old, Atom-based, slow server) chef-client -h went from 34s to 9s

FYI, the Chef 10.14.0 Omnibus release is planned to be built on Ruby
1.9.3-p194 and Rubygems 1.8.24. A release candidate should be
available on Monday.
