Best pratice examples...

From design to hosting, 115 best practices are tested and explained. Here are some examples, but be sure to check the other ones:

Hosting #90

Minimize the use of SSL certificates

Only use SSL certificates for sections and services where they are truly needed. This is because encrypting all of the HTTP data stream requires a large number of CPU power. And so encrypting a page’s static elements such as images (except the content) uses up considerable resources while presenting no benefits.

Development #170

Keep the number of domains serving resources to a minimum

When a website or online service hosts a web page’s components across several domains, the browser has to establish an HTTP connection with every single one. Once the HTML page has been retrieved, the browser calls the sources as it traverses the DOM (Document Object Model).

Some resources are essential for the page to work. If they are hosted on another domain which is slow, it may increase the page’s render time. You should therefore, when possible, group all resources on a single domain.

The only exception to this is for static resources (style sheets, images, etc.), which should be hosted on a separate domain to avoid sending one or multiple cookies for each browser GET HTTP request. This reduces response time and unnecessary bandwidth consumption.
