Comparing Rails 2.0 to 1.2 for speed and memory

Posted by David March 18, 2008 @ 07:23 PM

Hongli Lai has compared a dummy scaffold application from Rails 1.2 to Rails 2.0 and found the latter to be 30-50% faster. That’s great to see.

But what I think is even more interesting is the progress we’ve been making on performance optimizations for more substantial applications. Rails 2.0 made a lot of progress for applications with lots of assets and for ones with big routes.rb files. The forthcoming Rails 2.1 will move things forward even further.

UPDATE: Hongli also investigated memory consumption on 1.2 vs 2.0 and found 2.0 to be significantly slimmer. Nice!

    great! any predictions on when 2.1 might be released?

  2. Tim Harper on 18 Mar 20:38:

    I’ve noticed performance improvements in rails 2.0, without having to benchmark it :) This confirms that hunch.

    Great news, indeed!

    @Steph, how about we try and predict the release date of 2.1 together? We did pretty good on predicting Rails 2.0, we had Nov 8th predicted about a month ahead of time. It was pretty helpful to have an idea when planning our development schedule.

    Oh hell yes! I’m gonna make so much money on that :)

    Any news on getting Ruby 1.9 support in any future Rails releases?

  6. Brian Cardarella on 18 Mar 23:01:

    Never mind my last comment, I failed to check: http://dev.rubyonrails.org/report/68

    Ruby 1.9 support is listed

    It sounds good…

    @Brian Cardarella

    I just use Merb. Merb is thread-safe, Ruby 1.9 compliant, uses less memory and is faster than Rails.

    Great news. It sounds really good.

    @shawn

    That’s because you are totally awesomner than all us Rails loozers.

    I think you missed the point. Merb is simply another option with its own upsides (listed by Shawn) and its own downsides.

    It sounds REALLY good..nice!

    You are always my Ruby-Inspiration!

    Great. Now I want to know what makes 2.0 faster than 1.2
