Redmine

Redmine 1 runs Rails 2.x, Redmine 2 runs Rails 3.x.

For the most part.

Not knowing Rails really well (and neither the rest of the stack btw), I wonder:
From the end-users POV, is using Rails 3.x "better" than using 2.x and if so, in what aspects?

As far as I can tell: it's slower. ;) Though I think Jean-Philippe is looking into fixing some of that on the Redmine end if at all possible. As far as an end-user though, they're not going to see many changes (I'm not sure when/if the Redmine team is going to drop Rails 2.x support).

Mainly it's for us squishy programmers and to get on a newer (more secure? not too knowledgeable about the internals of Rails outside of the security fiasco a little while ago), better maintained framework. IMO: It seems to be a little nicer to develop plug-ins for.

I personally don't have any performance issues but my RM instance is not a big one and I use Ruby 1.9.3p125 (latest 1.9.3 patch seems to degrade severely the response time).

From Redmine 2.0.3 and 1.4.4 released: Rails 2.3.x is no longer maintained by the Rails team.

We're talking a sub-second amount at this point if I'm not mistaken, something you wouldn't really notice except in large deployments.

Ah so the 1.4.x security releases will be the last of the Rails 2 support. :) thanks.

Nope, have a read to RE: Redmine 2.0.2 performance tuning and install under Wi... thread. I guess that linux MRI version suffers from the same behaviour.

So I would have been better-off installing 2.x some weeks ago, because sooner or later rails 2.3.x will be discontinued? Perhaps it's a good idea to mention that somewhere on the download page...

I was referring to #4796 - Reply #43, his metrics indicate ~200ms response time increase at worse, which you wont really notice. Though that thread does detail that Ruby 1.9.3-p194 does appear to have a problem.
