June 7, 2025 — I am often hired to teach performance to WordPress developers, and every time I see the same problem: good, experienced developers feel unconfident when they face performance issues. They try to do various things but get no or insignificant improvement. This creates frustration and the stereotype that performance is a black box that only a few “chosen ones” can open. This is absolutely not true. What they really lack is a system to follow when identifying performance issues, to be able to solve the exact problems that cause these issues and get significant improvement with the effort they invest. I am going to present the algorithm that I use every single time I improve Core Web Vitals and explain step by step how to identify the issues that really need to be solved so that other developers can apply it in their daily work.

June 7, 2025 — The WordPress Speed Build Challenge is a fun live challenge, where two people battle it out against the clock and each other to replicate a website design in just 30 minutes.

June 7, 2025 — Taco will bring a team of experts to join him, creating a multi-disciplinary team experienced in various aspects of building a website. In a panel-like setup, the team will invite the audience to share their websites with them. They’ll review a few sites live on stage. From experience, Taco knows that every website has things we can learn from, either because they’re doing things really well, or because there are things to improve. By using real-world examples, we provide direct value to those who are brave enough to give us their site, and to those who secretly wished they had the guts to put their site in our crossfire.

They will make sure that there’s a fine balance between compliments and improvements, and that several websites will be reviewed.
