I'm watching the web cast now. Most PHP frameworks will pick up some performance gains. I'm curious to see how CI does due to the "magic code" they talk about (including based off functions) and how everything (models, classes, etc) are almost their own CI instance.

Depending on how the tests come back, I may drop CI and go back to an old in house framework we developed, that's MVC based but doesn't have the "magic code" that can't be optimized.
