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.
