For those of you familiar with M. Hartl's RoR Tutorial, do you know if the latest authentication system taught in the book is full proof for a large scale application or would you recommend going in with a ready made authentication systems like Devise or OAuth.
I find the system taught in the book very easy to follow as compared to the ready made systems. I am just not sure if there are any security loopholes in it.
Go with Devise.
Rolling out your own authentication system is great for practice, but many minds beats one, especially when it comes to security.

I am beginner in ROR. I am working on one project. I want to know the better option between for deployment of the app.
My answer will be more conceptual, rather then technical.
This is the first time I hear about Google App Engine in case of Rails. This is mostly a crucial reason, why I would say, that you definitely better go with Heroku.
While you are a beginner, it's better to use the most widely spread solutions and tools. Heroku has a huge history and you can find any answers in the internet very easily. It's well known among rails community and everyone can make a small consultation according to it.
Even if Google App Engine would be better or cheaper (haven't checked it), you shouldn't start such experiments until you have good deploy/rails knowledge.

I know this is the kind of question that usually gets deleted, but I have to find some answers. I want to build a project in a new technology more suitable to hosting on a Linux server, but I like the way things are done in ASP.NET MVC. I've looked at Rails a bit but I've heard that Rails performs and scales poorly. Any suggestions appreciated.
Ruby on Rails doesn't scale well, but depending on your needs you may never have to worry about it.
My guess is you'd be most comfortable with something like CakePHP or just PHP and whatever MVC framework. It's pretty C# like, and it's FAST!
Python/Django is also a good choice. (My personal favorite)

I'm a Java developer and I really want to get into Rails. What have you found to be the best way to learn RoR?
Seriously, any tips/tricks/rants would be awesome.
I'd definitely recommend using Michael Hartl's Ruby on Rails Tutorial book. I've also found Daniel Kehoe's Learn Ruby on Rails e-book super helpful as well.
On a personal level, finding a project I actually wanted to build, as opposed to just pacing through a tutorial, is what really helped get me off the ground though.

I'm currently developing a rails app, based on Redmine, using a multitenancy approach. The app it is intended to be used by lots of users (at least I hope so :)), so it is important that it can handle several requests without compromise its performance. Having this in mind, I'm wondering which rails server would suit my needs best. I'm currently using thin, for memory savings purposes, but I'm afraid it is not the best choice for me... I've used unicorn before and I liked it a lot, but it was consuming a lot of memory and I had to change it to another one, but I've noticed that my app is not as fast as it used to be. Any advises? Thanks a lot in advance!
Use Passenger with Apache.

I want to use MVC for a big project, but I read in some website that this is not suitable for large projects.
Is this true? and are there examples of some great sites or application that have been written with this technology?
We built the site you are browsing with it.
StackOverflow is a 100k LoC ASP.NET MVC site, and is currently #66 #53 in the world for traffic according to Quantcast.
More in general, it matters much more how you use it.
Facebook is PHP based, twitter is Ruby based. Both are relatively slow interpreted languages, and yet, they work!
