Of course, when we are optimizing the performance of our Magento website, we must make sure that we are analyzing the speed variations so that we know that our efforts have a positive effect.
There are many page-speed testing tools out there, but a few of the best (particularly for Magento-powered websites) are:
Mage Speed Test
Pingdom Website Speed Test
Google Page Speed Insights
This tool, written by Ashley Schroder, is specifically targeted towards Magento-powered websites. It takes sitemap.xml from our Magento store and through a few simple settings, will measure how many times the server is successfully hit by fake users within a certain time frame.
The returned results are in the format of transactions per second (this is measured in web transactions, not Magento sales transactions) and ideally, the higher the number of users per second, the better.
You can try out the tool yourself by visiting www.magespeedtest.com.
