SignalR was built with scalability in mind. Even though you will be able to run a fair number of concurrent connections on a single server instance, there will come a point where a single node will not be able to handle the load.
You may consider storing the content in a resource file and embed it in a class library. Or perhaps do a clever virtual directory mapping in your IIS setup. However, the best solution is simply to compile the views into a class library using Razor Generator.
A larger web projects would typically consist not only of front end web project, but would include additional class libraries and offload some of the heavy processing work to service or console apps. The common problem is then how do you update the front-end and signal the site that some work has been completed.

The Clients dynamic property of the Hub gives you access to all clients connected to the hub within the hub class. However, what if you would like to push data to the clients from outside of the Hub class. One of the most common scenarios is when you want to push data to the clients from an admin system in your back-end.
SignalR is an open source async signalling library. It was made by David Fowler and Damian Edwards. In a nutshell, it allows you to pass data between client and server in realtime. It’s not only for web, it has JS, .Net, WP7 and Silverlight clients and supports self-hosting so you can run the SignalR server in win service or web context. It will run on .Net 4.0 or 4.5 and to get websockets running, you will need IIS8 or IIS8 Express. That said, it will run on older versions of IIS and will switch to different transport modes.
The new System.Web.WebPages 2.0.0.0 assembly that ships with the latest MVC4 contains a pretty cool feature that lets you override the current browser capabilities. Sure, most modern browsers let you set a custom user agent string out of the box or via extensions. However, there are certain scenarios, where you would want to switch the user agent on the server side. That’s where the BrowserHelpers class comes in handy.
In the previous post, I went on about how to use System.Web.Optimization library to minimize your page load times. However, the new library offers quite a lot of extensibility and even if you don’t want to use the default minification, you can still use the framework.
Minimising the number of requests the page has to perform can have a considerable effect on your site’s performance. IE6 and IE7 both limit the number of concurrent requests to 2, IE8 can handle up to 6. There is a lot you can to improve the initial load speed speed – one of which is bundling all your CSS and JS into two separate files. How much of a difference it could do. Well, as it turns out up to 30seconds on slower connections.
