that is a huge span of time, with the birth and death of stars in-between in the Web Development cosmos. So much has changed in Web Dev, especially for mobile.
The issue is not the Web getting slower. It's with the developers and their companies focusing on the time to iterate. We have traded consumer convenience for speed to develop and using shiny new tech/methodologies.
We have traded doing things server-side to having most things in an SPA; using tracking pixels and Google Analytics to now also incorporating New Relic, Optimizely, a host of CDNs, bot protection scripts, social media scripts for "better personalisation", CAPTCHAs.
I feel we are moving backwards. Back to when developers used ActiveX plugins because it was more convenient for them. Only ActiveX is now a combination of "Javascript in the browser, and a powerful enough laptop to handle it without choking".
