Optimize Site Loading Time
User experience of a website largely depends on the response time of a website. And response time depends on the number of components in a page.
Each component requires an extra HTTP request. Browsers generally download two components in parallel per hostname. Most of the website download all there components from a single hostname and for them you will see a stair – step pattern as shown below.
By default both Firefox and Internet Explorer sent 2 http requests to one host at a time, but this can be changed by the user, firefox setting is controlled by network.http.max-persistent-connections-per-server, in about:config page. For IE setting check out Microsoft Help and Support
But instead of relying on the users webmasters could simply use DNS aliases to split there components across multiple hostname. But just remember parallel download can degrade your site performance. Now if your components are distributed in two hostnames then the HTTP pattern request will look something like this.
This will definitely help in decreasing your site loading time which will in turn help you in increasing your site user experience.

Great!
This is certainly a good news for the web commuters…its because of a thick loading-time that many of us quit web-pages…it truly sounds worthy of solving a never-ending trudging process…
I think this can be a good options to optimize the download speed of a site. Have you tested this?
I think an example can help us to understand this process better.

Yes Susenjit da this has been tested…you can check sites like amazon and yahoo they have there images coming from another hostname.
Thanks Anirudh for sharing the knowledge. It’s really an interesting concept. We can shift css, images, scripts on other server. http://www.die.net/musings/page_load_time/ It seems to be an informative article. It’ll be a gr8 time when we can work on it and make it happen for our sites.
Keep posting
Yup a lot of things can be done to optimize the pages. These are some starting stuffs that you can do keeping browser limitations. Opera has 5 parallel connections, a smart programmer can help you decide how many subdomains are required for a particular page but max is 4, above it will not help with the default settings.
Tremendous post man!I think you are getting better with blogs everyday.now its time to take the post of blog manager[:)]….Good post.
