Make Rails 2.3.x happy with Ruby 1.9.3
If you’re like me, you still have some Rails 2.3.x apps hanging around. Yeah, Rails 3 is awesome in some respects, but that “2x performance increase” never quite materialized.
In fact, for the most part, Rails 3 is still slower than Rails 2.3. SIGH!
Nevertheless, Ruby itself is progressing nicely. Ruby 1.9.3-p0 was released a few months ago. With faster garbage collection, startup, and file load times, Ruby 1.9.3 is where it’s at.
The only question is: What do you do to make Rails 2.3 play nicely with Ruby 1.9.3?
It’s actually not that hard!
