Which java script framework suits best to develop a technical forum application ?

I have the working knowledge with angularjs and want to develop the application using that only. But i hear that angularjs is little slow in performance when it comes to develop a big application.
.
The problem is i like to code in angularjs and i doesn't want to degrade the performance of application. So what should i have to go for ?

1. angularjs
2. backbone js
3. regular js
4. Serverside web framework like struts,JSF, spring MVC
