Web accelerators increase the performance of web applications by handling long-distance communication with clients, saving resources like memory and sometimes CPU on the application server. They work by acting as a proxy or load balancer between clients and servers, taking over communication and caching frequently requested content to improve response times for users. For example, the website DANDB.com saw improved performance when placing their application behind a web accelerator proxy.
