On: In spite of an increase in Internet speed, webpage speeds have not improved

Facebook desktop web is far from being optimized. On my fiber connection & high-end non-Mac laptop, loading "Messenger" tab takes about 15-20 seconds.

Having said that, FB and Google properties (like YouTube) have insane edge over the rivals by having full control over the advertising stack.

Facebook and Google properties (moreso than google.com) are among the slowest major sites.

Something strange is happening if messenger takes 15-20 seconds. You should investigate further.
