An ISP can still be slow serving web pages, e-mail, or other data even if an ISP has plenty of bandwidth because its load and latency affects the delivery rate. The reason is that each ISP service is handled by a separate program called a daemon and these individual daemons can get overloaded. Each daemon can only handle so many requests per second regardless of bandwidth. Basically in addition to the ISP’s global load, there’s also individual service load. The number of requests an ISP service can handle per second is based primarily on its server software.
