For Rubyists Out There — Upgrade to 2.0

We recently upgraded from Ruby 1.9.3 to 2.0.0, and this simple upgrade had a dramatic effect on our application server load. We had been pushing 3 cores at peak, but on 2.0, we're rarely pushing 2 while serving a comparable request load.

Aside from updating a few gems, 2.0 was a simple upgrade, so if you're still hanging out on 1.9.3, consider this your nudge!
