Test your website loading speed with LORI Firefox Extension
How long does it take your web page to load?
LORI (Life of Request Info) can help you understand how long it takes your pages to load within a Firefox browser.
I do have to qualify the above sentence with “within a Firefox browser”, since each browser renders and handles the code differently. It at least will help you pinpoint any problems within your web page that maybe slowing it down.
LORI installs on the bottom status bar and provides 4 statistics.
From left to right:
- Time to First Byte – this is the time it takes from the initial click to your website to the time it takes the first byte to load
- Time to completion – this is the total time it takes the entire webpage to load from initial click to complete display
- Page Size – the actual page size in kilobytes
- Number of requests made by your web page
Overall the faster your page loads the better. I will write another post sometime about standards in this area. Basically, try to make your web pages load in under 8 seconds and limit the amount of requests it makes. The latter is affected by number of images, etc. on the web page.

Hiya, it would be useful if you also included the link to the LORI extension in this post.

Anyone know of a tool (nice it was a FF extension) that could emulate the page loading over dialup… would be good for development and testing of websites.

@Olmec:
Yes, “YSlow” is a Firefox extension that does that. Well, technically I think it’s an extension for Firebug, which is an extension of FF. So an extension within an extension? Haven’t tried it, but I’m thinking to.

[...] to make sure your app can handle high load is to get your per-request time very low. There is an extension for Firefox that provides TTFB (time-to-first-byte) information that will help you measure this. (Trace.axd is [...]
