Of the many factors that affect page-load speed, media is a significant one.

A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”.

We become annoyed when we run a speed test on our broadband provider only to find that, on a good day, we are getting maybe half of the rated download speed we are paying for, and the upload speed is likely much worse. But to prevent running afoul of latency (the 2 nd fallacy), we must also be careful not to download too little!
