Dan Luu on the sorry state of web performance:
…it’s not just nerds like me who care about web performance. In the U.S., AOL alone had over 2 million dialup users in 2015. Outside of the U.S., there are even more people with slow connections.
This other note is also interesting, and I think that Dan is talking about Youtube’s project “Feather” here:
When I was at Google, someone told me a story about a time that “they” completed a big optimization push only to find that measured page load times increased. When they dug into the data, they found that the reason load times had increased was that they got a lot more traffic from Africa after doing the optimizations. The team’s product went from being unusable for people with slow connections to usable, which caused so many users with slow connections to start using the product that load times actually increased.
