The process of improving a site’s front-end performance can be a daunting task, and it’s disappointing when those optimizations don’t have much effect on the metrics that actually matter. The most pragmatic (and rewarding) approach to web performance is one that takes advantage of all the quick, high-impact tactics that are available, while remaining focused on a robust, long-term performance-oriented strategy.

This talk will present ten concrete ways you can improve web performance, split between quick tactical wins and longer-term overarching strategies. With these practical tips you’ll be able to start making the changes that will meaningfully improve the performance, and overall user experience, of your web application.

Excellent talk! I learned a bunch of new tools/techniques for getting more front-end performance and UX. Very informative and useful talk.

Good talk, did learn some cool JS tricks, some items or more debatable, like only loading items above the fold, and then loading it after the user starts scrolling. This would cause a lot of extra network traffic and may cause scaleability issues, something the speaker didn't mention.

Reason I only give a 3 is because technical details how to actually implement some suggestions where not mentioned.
For example, "prioritize the downloading of assets in a certain order", is a cool tip but he didn't explain at all how to actually do it.

This was a comprehensive overview of frontend performance concerns - and I really enjoyed hearing a frontend focused talk at this conference.

I felt however although there were lots of suggestions on what we could do, there was missing key information about both how to implement these strategies and the pros and cons of doing so.

I'd suggest narrowing the topic down to a few of the big points so that more detail can be included.

Some of the javascript api functions mentions I hadn't considered using, so for that reason alone this was worth attending.

Good talk. Andrew covered a lot within a short space of time. I took away several useful things that I could try or consider. Considering the amount of things covered, I feel it's fair that they couldn't all be accompanied with a great deal of detail or examples. Andrew also gave a great deal of advice afterwards. He's very approachable and helpful. Thanks Andrew!

I agree with other commenters; there was a lot of generally good advice but not much of the actual nitty gritty. It would have been nice to see more examples. However, I did take away some ideas including the use of GraphQL for APIs (which I have heard of, but not heard why this would have been a good idea). Thank you.

Really good talk and I've learnt a lot. The only reason for the 4 stars is that I was eager to see more explanations of some of the the topics. Perhaps 10 is too much for this talk due to time restrictions.

A practical and helpful "refresher". Could have had a bit more on HTTP2 ?

I liked the fact there was a front-end talk early on in the conference. This did cover items at a reasonably high level, with implementation details left o attendees to discover in their own time. Well presented.
