I have the perfect Firefox extension for any special hosting guru in your life. When it comes to trouble shooting issues with a Web page, the life-of-request information extension, otherwise known as lori, takes the cake at being useful enough to use, but not so complicated you don’t know what is going on.

So what exactly does this extension show you? Here is the rundown:

TTFB: This shows how long it took to see the first byte from remote server (from click to first byte received). This value gives a rough estimate on when the browser can start laying out the content.

TTC: How long it took to display the page (from click to complete drawing of the page)

Page Size:: This value includes both bytes fetched from network and bytes fetched from the browser’s cache.

Number of Requests: Number of requests used to fetch the page’s content (images, style-sheet, javascript, ect). Again, this value include both network requests and cache requests.

For more information about lori, check out the official Web site. To download the Firefox extension, check it out on the Mozilla Add-ons Web site.
