Think I'll wait until this non-blocking issue is cleared up:<p><pre><code> I created two barebones Rails projects. One with Rails
3.0.7 and the other with 3.1.0.beta1. Both are using
Ruby 1.9.2p180 and SQLite for the db. Running this very
basic script with Rails runner, Rails 3.1 takes twice as
long to load in 3.1 versus 3.0.
. . . on our larger apps, we are seeing 20+ second boot times.

Congratulations to the Rails team! My team is building in Rails 3.1 and our tests are showing good results. The new asset pipeline is <i>great</i> and HTTP streaming makes for a much smoother user experience.
