WE LOVE SPEED. WE LOVE PERFORMANCE. THAT'S WHY WE DEVELOPED BEST WEBSITE SPEED TEST TOOL TO MEASURE PERCEIVED PERFORMANCE.We solved performance issues of many websites ranging from single page low traffic websites to complex high traffic websites.When we are working with our clients, every time we wanted to see how their website is performing from the user point of view on different devices. We did not find any solution to measure Perceived Performance across different devices. So, we started developing it by ourselves. Using Deep Learning techniques & other Algorithms in Artificial Intelligence, we are able to measure Perceived Performance. Right now we are accurate 95% of the time and we are confident that we will reach 99.9% accuracy very soon as we get more data.We are passionate about faster websites and we will be more than happy if Perfhack helps our users to make their customers happy by providing faster websites.
