There are various free platforms available online which can provide you with any specific web page architecture, their performance statistics, and bottlenecks along with the recommendations as to how you can overcome these bottlenecks. I’ve rounded up 8 website performance testing tools to help you make your website blazing fast. You simply supply your URL and your website performance test is underway.
WebPageTest is my favorite website performance tool for quickly testing what is wrong with a slow loading site.
This is another excellent tool similar to the one above. Many people like it because you get your Google PageSpeed Grade and your Yslow Grades.
Pingdom provides excellent monitoring services but they also include a free full page performance testing tool. The main report is a waterfall view your sites load times.
They provide both mobile and desktop testing. Interestingly, they default to the mobile view.
Y-slow is a web page speed testing browser plug-in (launched by Yahoo) which is available for almost all the modern browsers except IE.
A collection of tools for hosting speed checks, DNS checks and more. They keep moving things around and adding/removing features.
is my favorite tool for evaluating client-side performance from real browsers.
This is not a general performance tool but a tool we use. You can manage multiple WP sites from a single location.
