Used to be far better. Don't know if it's Windows 8 causing the issues but now only displays the overall page load time but the breakdown no longer charts properly. Needs fixing.
Simple, works perfectly, exactly what I need
Nifty.
very good
It's good!. i like it.. a quick way to see page loading time. previously i used to look this in "inspect element"... But this is really great!
Very useful as it helps a lot to check the page load speed..
Good one. love it!
Simple - does exactly what it says on the tin
doesn't work
Very useful for basic page load times, but doesn't work well when iframes update data in a page view. It only shows the last full page load time.
