A developer’s guide to rendering performance

When we look back over the history of web performance we see a heavy focus on reducing the number of requests and getting files to the browser quickly. Our platform has changed a lot, and while optimizing for network performance remains a crucial part of our jobs, we now have to broaden our performance horizons. Our users also expect smooth scrolling, animations and interactions, even on mobile devices. In short we need to deal with not just how quickly our sites and apps load, but also how quickly they run.
In this session Paul takes a lightning tour of how Chrome converts the DOM into pixels, see how our code affects its workload, and arrive at a modern workflow for finding (and eliminating) rendering bottlenecks.

JavaScript – the structural Problem

Interesting talk of Oliver Sturm about “JavaScript – the structural Problem”, presented at the webTech 2013 in Munich.

This talk explains and analyzes several approaches and tries to put them in their respective places.


Jetzt wird’s schnell – Performante Webanwendung


Jetzt wird’s schnell – Performante Webanwendung mit MongoDB” by Michel Krämer

Relationale Datenbanken sind langsam, zumindest wenn man auf ein Datenmodell angewiesen ist, das einfach nicht so recht passen will. Könnte da eine moderne NoSQLDatenbank
nicht Abhilfe schaffen? Dieser Vortrag beschreibt am Beispiel eines webbasierten
Geoinformationssystems, warum die Nutzer mit MongoDB näher an den Daten sind.
Selbstverständlich werden hilfreiche Hinweise aus der Praxis geliefert und es gibt auch
Code zu sehen.
