Google website Performance optimization Tool page Speed

Like Yahoo's YSlow, Google's Open source Web site Optimization Tool page Speed is a firebug based Firefox plug-in, and, like YSlow, page Speed can help users improve the performance of their web site. After running it, you can see a list of suggestions to help your Web site load faster, and it will check your site against each item in the list and indicate if it's passed.

Page speed analyzes some Web server configuration and server-downloaded code at run time, and creates a list of results, including suggestions on how to improve the Web page. The analysis is based on a list of best practices grouped into five categories:

* Optimize caching-lets you apply the data and logic completely avoid using the network

* Reduce response time-reduce the number of requests-response cycles

* Reduce request size--Decrease upload size

* Reduce payload size--reduce response, download, and cache page size

* Optimize Browser rendering--Improve the page layout of the browser

These practices take into account the page load time and the time between when a page request is sent to the client to see the result. Page load times include creating TCP connections, resolving DNS names, sending requests, fetching (including from cached) resources, executing scripts, rendering.
