October 26, 2018 — In this talk, I will tell how to cache rarely updated data to reduce the number of database queries and improve page load time by using built-in functionality in WordPress. Whether you are an experienced developer or not, you will find advice to develop your working!

July 9, 2018 — Utilizing caching mechanisms in a WordPress product is a balancing act: what remote calls are cacheable, what queries are slow and only occasionally needed, and how will it all impact the end user? In some cases we can set up our environment for a base level of performance, and in others we’ll need to balance data storage (like autoloaded options) and other background processes so they take the overall environment into consideration. I’ll be including my own experiences as a web developer working on a large-scale WordPress multisite as well as sharing the perspective from a hosting company’s point of view.

March 18, 2017 — In eCommerce, speed is your most important metric. Mere milliseconds can mean the difference between a sale and an abandoned cart, which could mean millions of dollars in lost sales.

Using real-world examples, I’ll show you the results I’ve been able to achieve and how to replicate them yourself.

April 21, 2016 — Vieles können wir im Internet über das Thema „Wie mache ich meine WordPress Seite schneller“ lesen. Leider findet man all zu oft nur einseitig dargestellte Lösungsansätze ohne Erklärung des „Warums“. Auch werden nicht selten Dinge von Marketing Menschen und Firmen in den Himmel gelobt, die schlichtweg keinen reellen Nutzen haben. In seiner Session möchte Jan die gängigen Performance Optimierungen aufzeigen und diverse Methoden als totalen Schwachsinn (für die große Mehrheit) entlarven. Die Methoden, die von jedem Anwender nutzbar und auch mit wenig Aufwand umsetzbar sind, möchte er kurz technisch erläutern, um es uns zu ermöglichen, tatsächlich selbst zu verstehen, warum eine Maßnahme funktioniert und andere nicht. Einleitend wird er anhand einiger bunter Diagramme aus dem wahren Leben aufzeigen, wo ein WordPress (wenn überhaupt) „langsam“ wird. Dabei werden Themen wir Browser Caching, Server Caching, Varnish, CDN, Minifizierung, Komprimierung, sowie die Frage, wo eine Optimierung vorgenommen werden kann und soll auf- und erklärt. Nach seinem Vortrag sollten diverse Lachmuskeln trainiert worden sein und einige Einhörner im Auditorium ihr Unwesen getrieben haben. Im Idealfall werden wir zukünftig weniger auf die sinnfreien Marketingsprüche diverser Anbieter reinfallen, die z.B. das CDN als Gottes Antwort auf Ladezeiten anpreisen. Auch soll die Hilfe zur Selbsthilfe im Vordergrund stehen mit direkten Tipps und Tricks die wenig kosten und viel bringen.
