One of our clients is a performance driven media company. They needed a complex solution for serving automatically text, image, video and interactive media advertisements to targeted clients. We chose to build the platform with PHP. With time it gained momentum and has began generating several million events daily. Since Apache + PHP-FPM couldn’t handle all the requests, the response time increased and some of the requests were on the edge to be rejected. For a service of this kind this would have been devastating. We needed something more powerful and swift. That's when we turned to ReactPHP.
