JSOxford Annual Performance Review
⚠️ We're in a new venue at St Gregory the Great Catholic Secondary School ️ ⚠️
We'll be in the "conference room" that is through the main entrance of the old building and to the right. We'll be about to direct people.
There is plenty of parking available and a main bus route close by. Once you arrive enter through the entrance marked on the map below.
We will be providing drinks and snacks thanks to our wonderful sponsors but please be aware the venue doesn't allow alcohol so we'll be providing a range of tasty non-alcoholic beverages.
Arrive, mingle, and meet new people
Welcome and thanks
Andy Davies - rel=preload
"Consider using to prioritize fetching resources that are currently requested later in page load" is the seemingly simple advice Lighthouse gives us.
How do we ensure we use preload's capabilities effectively?
Data from the HTTPArchive shows only a small number of sites are using preload. Some sites are using preload effectively, some have been tripped up by subtleties in how browsers and servers behave, and other cases it's actually making the site slower, so using preload effectively isn't as straightforward as it may first seem.
Chat, mingle, have a drink, and soak in all you've learned so far.
Doug Sillars - Stop Stalling! Delivering Fast Video without the Buffering
Video is one of the fastest growing mediums on the web and in mobile applications. Video files have been shown to increase engagement, and can be a great way to deliver your message quickly. (And who doesn’t love animated GIFs?)
However, video that takes a long time to start up leads to frustration and abandonment. The same goes for video that stalls during playback.
In this talk, you’ll learn best practices to optimize the delivery of your video to you customers, ensuring fast delivery and minimizing stalls for a great customer experience.
