> One consistent message from redditors has been that performance on the site and native apps could be better. We agree. That’s why the Reddit engineering team is working on making the Reddit platform faster and more reliable.
> A quick heads-up–this section is for engineers and robots. If you like a bit of nerdy tech talk, read on. If you don’t want to get lost in the technical details of what it takes to keep a site likeReddit running, you may want to skip ahead to the ‘Excellent’ section.
> Improving platform stability
> Last year, a major priority was improving feed load times (also known as Cold Start Latency) so that redditors could tap into their feeds and scroll through posts quickly, without waiting or watching little blue spinners tell them the page is loading. Because of those efforts, we saw drops in wait times across the board—iOS went down -11%, Android -19%, and the backend was down -25%. We also made improvements that reduced crashes and errors, resulting in a 64% reduction in downtime and a 97% reduction in background error rate.We’ll continue to invest in these sorts of latency and stability improvements, while also investing in a design system to componentize Reddit’s user interface (UI).
> Making Reddit faster, faster, faster!
> Another big factor in a webpage’s performance is how much stuff it loads. The number of requests for assets, the size of those assets, and how those assets are used are all good indicators of what sort of performance the site will generally have. Reddit’s current web platforms make a lot of requests and the payload sizes are high. This can make the site unwieldy and slow for redditors (especially in places that may already have slower internet service).
> We’ve already begun work on unifying our web (what some of you call new Reddit) and mobile web clients to make them faster, clean up UX debt, and upgrade the underlying tech to a modern technology stack. (For those interested in such things, that stack is Lit element, Web Components, and Baseplate.js. And the core technology choice is server-side rendering using native web components, which allow for faster page loads.) Stay tuned, because we’ll be sharing more on these efforts later in the year, and there’s some exciting stuff on the way.
