Push has been much anticipated since the finalization of HTTP/2. However, much like using a hammer on screws, Push is not always beneficial for performance. Looking at real-world examples, Colin Bendell explores Push’s possibilities—and its pitfalls and challenges—as well as new metrics to measure the Push opportunity. Colin also discusses how Push compares to other existing browser optimizations like the preloader, preconnect/dns-pretch resource hints, and service workers.
