Same app, same Ruby version (1.8.7p249). > Anyone seeing something similar, or (hopefully) better? > Andre, Rails 3 is still currently in beta. Thus, the Rails core team are still fixing relevant bugs, cleaning up overall functionality, and the optimizations will come. Also, Rails 3 performs much better with Ruby 1.9.2 than 1.8.7 but your mileage will vary depending on your platform. In short, Rails 3 beta has been deployed into many production environments but it hasn't been released as production ready system. The release candidates (RC) should be coming soon after the beta period which will be fully optimized for running your performance tests before we see a final release. Good luck, -Conrad ps: I'm basing this information on previous releases of Rails where we go through the following phases: alpha, beta, release candidate, and final. Thus, the software development work flow may or may not have changed for this version of Rails. > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]<rubyonrails-talk%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
