| WebSockets enables the real-time web where the information is available to the user the moment it is published. WebSockets are standard based, Interoperable across browsers and very simple to use. We got the WebSockets support everywhere it is available on browsers, windows run time, WCF, ASP, IIS etc. This post gives you the basic idea about WebSockets and the technicalities behind this concept. |  |
There is a deep desire for speed to get the information as quickly as possible.
Typical examples where user wants to see the information in real time
- Stock Market data
- Live Scores
- Airline Location
- Twitter Search Results
- Interactive games

1 commentOptimizing the website Performance using ASP.NET 4.5
| There are so many different ways you can optimize your website performance. You may think why we need to worry about website performance when internet connection speed is growing faster and faster. Just few examples: Google did a test, if their search page is 500ms slower then they are going to lose 20% their traffic. If Amazon runs 100ms slower then there is 1% drop in their sales which is nearly $1 million a day. So it is important build the website which are fast in response time. |  |
Typical website may have the following architecture. We can do optimization in each layer but this post specifically talks about ASP.NET 4.5/IIS which is a presentation layer.

- You may setup your Database First – Creating a Schema and generating model from it. Here model is a class which you are going to interact with your database from your code.
- You may setup your Model First – Instead of designing the database first, we design the entity model first eg: using entity framework. Design your model first and then generate a schema and code.
- You may setup your Code First- In this approach you first write code to design the model and then generate a schema using that code.
