Current behavior While bootstraping the application, I see system is loading individual rxjs files. (100+ calls)

Expected/desired behavior Shouldn’t it load RXJS bundle same like other angular libraries?

Reproduction of the problem If the current behavior is a bug or you can illustrate your feature request better with an example, please provide the steps to reproduce and if possible a minimal demo of the problem via https://plnkr.co or similar (you can use this template as a starting point: http://plnkr.co/edit/tpl:AvJOMERrnz94ekVua0u5).

What is the expected behavior?

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 2.0.0-rc.4
• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]
• Language: [all | TypeScript X.X | ES6/7 | ES5 | Dart]

I think it’s up to you to bundle your application as you wish.

Not all of us have the time to invest in the labyrinth-themed maze that is package bundling just to achieve decent loading times in Angular 2.

For what its worth, the reason we don’t bundle Rx for you is to not bring in 300KB+ of extra dependencies you may not need, which would of course increase your loading time.

This is non-trivial to solve to keep everyone happy, because like many things in angular2, we are optimizing for the future. Bundling is not going away and we will continue to optimize for the case that allows for smaller package sizes.

RxJS does currently ship a SystemJS bundle, it’s the /bundles/Rx.js file, which would give you all of the dependencies angular needs as well as the entire Rx library.
