#### Editor’s note

According to HTTP Archive, the median total transferred size of mobile sites rose over 11% just in the last year. Now, imagine a situation where your mobile plan allows 300 MB data a month and is of maximum 4G speed. The growth in page bloat is going to significantly impact your capability to communicate with loved ones, check essential services or get information you need.

The core principle behind web performance is making all websites and apps accessible to anyone, anywhere, no matter their device, network, or internet plan limitations. This is our imperative, our north star.
