Want to know if how much time your blog takes to load on a browser or to know which component in your blog is taking the longest time to load ? Try Octagate SiteTimer. This AJAX service analyzes a blog and displays how much time it takes for each component in your blog to load.
The mechanism is simple. You specify the URL of the blog you want to analyze. Then SiteTimer visits your site and downloads each and every frame, image and other web components. Finally SiteTimer displays in a AJAX interface how much time each and every component takes to download.
You can see the analysis of this blog below. 
From the graph, you can analyze exactly why your blog is loading slow and which component is taking the longest time to load on your visitor’s browser. You can then optimize the loading time of your blog by moving that component to a faster server or reducing the size of the component or even removing it, if it is not of much use.
