Are there new Web Performance Rules since Steve Souders started the WPO movement about 10 years ago? Do we still optimize on round trips or does HTTP/2 change the game? How do we deal with “mobile only” users we find in emerging geographies. How does Google itself optimize its search pages and what can we learn from it. In this session we really got to cover a lot of the presentation Pat Meenan (@patmeenan) did at Velocity this year.Related Links:* Scaling frontend performance - Velocity 2016***** https://www.youtube.com/watch?v=LdebARb8UJk * WEBPAGETEST***** https://www.webpagetest.org* Google AMP***** https://www.ampproject.org/***** https://github.com/ampproject/amphtml

Pat Meenan (@patmeenan) is a veteran when it comes to Web Performance Optimization. Besides being the creator of WebPageTest.org he has also done a lot of work recently on the Google Chrome team to make the browser better and faster.During his recent Velocity presentation on “Using Machine Learning to determine drivers for bounce and conversion” he presented some very controversial findings about what really impacts end user happiness. That it was not rendering time but rather DOM Load Time that correlates with conversion and bounce rates. In this session we dig a bit deeper into which metrics you can capture from your website and presented them to your business side as an argument for investing in faster websites. Find out which metric you really need to optimize in order to “move the needle”Related Links:* Using machine learning to determine drivers of bounce and conversion - Velocity 2016***** https://www.youtube.com/watch?v=TOsqP16jnDs* WEBPAGETEST***** https://www.webpagetest.org/* WPO-Foundation Github repository for machine learning***** https://github.com/WPO-Foundation/beacon-ml

Adam Auerbach (@Bugman31) has helped Capital One transform their development and testing practices into the Digital Delivery Age. Practicing ATDD and DevOps allows them to deploy high quality software continuously. One of their challenges has been the rather slow performance testing stage in their pipeline. Breaking up performance test into smaller units, using Docker to allow development to run concurrency and scalability tests early on, and automating these tests into their pipeline are some of the actions they have taken to level-up their performance engineering practices. Listen to this podcast to learn about how Capital One pushes code through the pipeline, what they have already achieved in their transformation and where the road is heading.Related Links:* Hygea Delivery Pipeline Dashboard https://github.com/capitalone/Hygieia* Capital One Labs http://www.capitalonelabs.com/#welcome* Capital One DevExchange https://developer.capitalone.com/

Do you speak SQL? Do you know what an Execution Plan is? Are you aware that large amounts of unique queries will impact Database Server CPU and also efficiency of the Execution Plan and Data Cache? These are all learnings from this episode where Sonja Chevre (@SonjaChevre) and Harald Zeitlhofer (@HZeitlhofer) – both database experts at Dynatrace – pointed out database performance hotspots and optimizations that you many of us probably never heard about.Watch the Online Performance Clinic -Database Diagnostics Use Cases with Dynatracehttps://www.youtube.com/watch?v=pEXfqzE-WQM

Are you still exporting load testing reports into Excel compare different runs manually? Matt Eisengruber – Guardian at Dynatrace – walks us through the life-changing transformation story of one of his former clients who used to spend an entire business day analyzing LoadRunner results.Through automation, they managed to get her the results when she walks into the office in the morning – giving her more time to do “real” business analyst work instead of doing manual number crunching. Matt shares some insights into what exactly it is they did to automate Dynatrace Load Test comparison, how they created the reports and which metrics they ended up looking at.

Alois Reitbauer (@AloisReitbauer) guest hosts - Mike Jones ( http://bit.ly/mjlnk ) takes us on a journey how the team moved a monolithic application that was built by a remote team to a micro service architecture. Learn how the manage a couple of million lines of code with only 5 people while improving performance and availability. Mike also shares lessons learned on their journey and shares strategies on how to make the transition to micro services while having to keep the lights on for day-to-day business.

Scott Stocker (@sestocker), Solution Architect at Perficient, tells us the background of a recent load testing engagement on an ASP.NET App running on SiteCore. Turns out that even these apps on the popular Microsoft platform suffer from the same architectural and implementation patterns as we see everywhere else. Bypassing the caching layer through FastQuery resulted in excessive SQL, which caused the system to not scale, but crumble. Scott tells us how they identified this issue and what his approach as an architect is to proactively identify most common performance and scalability problems.

The initial idea of the Cloud has long become commodity – which is IaaS. Containers are the current hype but still require you to take care of correctly configuring your container that will run your code. Mike Villiger (@mikevilliger) – a veteran and active member of the cloud community – explains why it is really PaaS that should be on top of your list. And why monitoring performance, architecture and resource consumption is more important than ever in order for your PaaS Adventure not to fail.Related article:http://www.it20.info/2016/03/the-incestuous-relations-among-containers-orchestration-tools/

In Part II, Richard Dominguez, Developer in Operations at PrepSportswear, is explaining the significance of understanding and dealing with bot and spider traffic on their eCommerce site. He explains why they route search bot traffic to dedicated servers, how to better serve good bots and how to block the bad ones. Most importantly: we learn about a lot of metrics he is providing for the DevOps but also the marketing teams to run a better online experience!

Have you ever wondered how to argue with a marketeer about not releasing a new feature or running this campaign? Or in the contrary: how can you show a marketeer that performance engineering and monitoring is as critical to the success of a campaign as the marketing campaign itself? Richard Dominguez, Developer in Operations at PrepSportswear, is enlightening us about how his DevOps team is cooperating with marketing to have a better shared understanding between business and technical goals!
