That's a very diplomatic assessment of Rails.

I administer multiple Rails applications - GitLab, a custom CMS, one
of the eCommerce packages, and a full Web application that was
developed in house.  I cannot believe how much of a resource drain
they are, even having gone through the pain of optimising the entire
stack.  I think the smallest RAM footprint I've ever seen out of Rails
is 450 MB resident.

This isn't even a Ruby problem; I have seen Sinatra using under 50 MB.

For a large Redmine install with a lot of users and some concurrency
(i.e. multiple people doing /something/ at the same time), I wouldn't
use a box with less than 2 GB RAM and dual-core.  And that's pushing it.

Look, I used to *be* a Rails developer.  I like the rapid prototyping
that it allows and I even *still* use it for that.  But it isn't
something I would ever choose to run in production.
