In my project, "rake environment" took 11.5 seconds on rails 3.1.x, and 8.7 seconds on rails 3.2. (1.9.3.p0 for both).

I'm quite happy about this, as the initial development boot time is what's been bothering me most lately.

View on HN

We see ~20% improvement with the same upgrade (on 1.9.3p0).

8.5s to 6.6s on my laptop (with SSD). Nice!

IMO, 6.6 seconds to boot the app is still too slow, but it's certainly progress. :)

Sure, but it's better than the 15 seconds on ruby 1.9.2 and rails 3. Things are getting better!

Seeing about 25% speedup here with just the Rails 3.2 RC1.

Combined with rspec-rails 2.8.0.rc2 (which includes some Rails 3.2-related changes), I saw my test suite go from ~2.5s (Rails 3.2.0.rc1 w/ rspec 2.7.x) to ~0.43s (Rails 3.2.0.rc1 w/ rspec 2.8.0.rc2).

Ruby 1.9.3p0 across the board.

Just upgrading to rspec 2.8 made my test suite run 10x faster. You might have David to thank for a lot of that speed up. :)

Certainly a LOT of it is rspec 2.8.

But there was a definite increase with Rails 2.3 as well. :)

I agree. 2.3 was much faster :-)
