Introducing Chasing Waterfalls

Rarely do we get to start with a fresh slate when it comes to performance, more often, we have to figure out how to make a performance transformation after the fact. In this episode, Sharell Bryant talks about Teachers Pay Teachers journey to a performance-focused organization.Luckily there were people in the company who had kind of had similar experiences in terms of being able and having the freedom to like run an A/B test where maybe it's not a product change, it's just a performance optimization change and being able to see like test out whether that improved various metrics. I was able to do that and felt empowered to do that. Especially when we are looking for different opportunities for how to improve the experience. If I can say, "Hey, I can make a quick performance change and let's just see if it affects these other metrics and you know, it won't involve design, it won't involve product and it'll take this much resourcing and then we'll measure it", I think was a great way to kind of advocate at first and loop it into another objective.A full transcript is available at: https://chasingwaterfalls.io/episodes/episode-six-with-sharell-bryant/LinksSharell Bryant on TwitterCompassionate action over empathyAlonzo Felix on TwitterAlonzo Felix's Anti-Racism GuideTeachers Pay TeachersCatchpointDatadogSpeedCurveSharell Bryant's 'Is the Site Fast Yet' talk

Performance is always important, but that's especially true for anyone providing essential services over a wide range of connections and devices. In this episode, Matt Hobbs talks about the challenges of building sites that perform well for the entirety of the UK.Everything that we do in terms of accessibility, in terms of web performance, in terms of content design, we have to be catering to the largest number of people possible because one thing that we can't, we can't just say, well we're not going to support X or you're not going to support Y. Because in doing so we may just be excluding a certain demographic of the UK.A full transcript is available at: https://chasingwaterfalls.io/episodes/episode-five-with-matt-hobbs/LinksMatt Hobbs on TwitterMatt Hobbs' siteSpeedCurve Page Speed BenchmarksTammy's post on SpeedCurve's BenchmarksGovernment Digital ServiceGOV.UK Design SystemPolyfill.ioChrome User Experience ReportLighthouseWebPageTestSiteSpeed.ioFrom Hackathon to Foundational Performance with Reefath RajaliGDS BlogTechnology in Government blog

You can do all the work to make your own code as fast as possible, but a few ill-performing third-party scripts can still bring your site to a crawl. In this episode, Karolina Szczur talks all about third-parties: how big of an issue they really how, how to identify which ones are the most problematic, and what you can do about it.So it's not necessarily a binary choice—in some cases, sure. But there are strategies that you can use to mitigate that performance that you just have to be aware of them and you have to start with having that conversation. The responsibility is actually on us, not necessarily on the vendor that's providing the service.A full transcript is available at: https://chasingwaterfalls.io/episodes/episode-four-with-karolina-szczur/Links:Karolina Szczur on TwitterKarolina Szczur's sitePatrick Hulce on TwitterCalibreThe State of the WebAddy Osmani on TwitterThird Party WebLighthouseFirefox FocusHow We Improved the Performance of Our Live Chat by 30%NetlifyHerokuGoogle found a 400ms delay resulted in less engagementReducing the Intercom Messenger Bundle Size by 65%Harry Roberts' tweet showing a performance waterfall with and without third-partiesBen Schwarz on TwitterPerformance Email NewsletterCalibre on Twitter

A lot of work falls under the umbrella of "web performance" and it's hard to know where to focus, both for quick wins and for long-term maintainability. In this episode, Katie Hempenius talks about everything from JavaScript and image weight, to third-party challenges, budgets and the importance of organizational support.Now maybe your first party site is actually pretty decent and is holding the line but you keep getting push back from marketing to just keep adding more third party content and that is just really slowing the site down and that's one of those things...that issue is bigger than engineering. You need to have the company kind of come to an agreement on what your strategy is going to be around third party.A full transcript is available at: https://chasingwaterfalls.io/episodes/episode-three-with-katie-hempenius/Links:Katie Hempenius on TwitterImproving Page Performance in Modern Web Apps with Katie HempeniusAddy Osmani on TwitterSpeed at Scale: Web Performance Tips and Tricks from the TrenchesHTTP ArchiveTweet about page size increaseLighthouseWebPageTestPageSpeed InsightsBundlesizeLightWallet77% of sites use at least one vulnerable JavaScript library

Many people want their organization to prioritize performance, but where do you start? In this episode, Reefath Rajali, a mobile developer advocate at PayPal, talks about PayPal's performance journey, starting with a simple, lightweight prototype built during a hackathon.So, that is how this journey actually started and as you said, it was not an easy journey. We had a lot of challenges. Because it is a larger organization and to transform a hackathon idea into action, there are a lot of team players and companies about. We have our product, we have our analyst, we have our designers, and we have our engineering group. So, it’s like four or five teams we have to come together, agree, and every single stream has a different leader.A full transcript is available at: https://chasingwaterfalls.io/episodes/episode-two-with-reefath-rajali/Links:Reefath Rajali on TwitterPolymerReactBabelCelebrating our achievements by Lara HoganLighthouseCatchpoint#perfmatters ConferencePayPal Engineering Blog

How do you not only establish a culture of performance, but nurture it and scale it across a large organization? That's the question we try to answer in this week's discussion with Malek Hakim, a performance engineer at Priceline. We talk about what Priceline has been doing to cement a culture of performance across the organization, touching on everything from tooling and metrics, to education and experimentation.We started small at first. We were actually working on trying to find small tasks that we can do that we can test and try to show the impact. And yeah. You iterate and you do different tests, and some of them show up to be beneficial and sometimes surprising. And I guess that gets the ball rolling.—Malek HakimA full transcript is available at: https://chasingwaterfalls.io/episodes/episode-one-with-malek-hakim/Links:Malek Hakim on TwitterNew York Web Performance MeetupLondon Web Performance MeetupSergey Chernyshev on TwitterBoomerangLighthouse
