Speed Analyzer helps to analyze the performance of every block and template in the Magento® site. With precise Block Loading time, Speed Analyzer helps to track down the block which consumes majority of the bandwidth. Speed Analyzer shows Path of Template and Block , Loading Time and Count.
Based on the data obtained from Magento® Profiler, Speed Analyzer depicts the data across each block so that the high bandwidth block can be optimized for better performance.
The standard Magento developer option to 'enable template path hints' is always a bit of an effort to get to as store/website scope has to be selected. This module makes it a little easier to get template hints on (and off) as there is no need to specify store scope.
The numbers in the boxes are clearly presented and, within seconds of looking at your site, you will realise that for many of those seconds Magento was rendering 'price.phtml'.
I will probably have this extension as important to my development toolkit from now on.
the speed analyzer helped us understand where the load issues were in our site and we were able to make updates that changed the speed for our trouble pages. Works great and DCKAP is a great company! their support is great.
