Very interesting, specially because he shows us which tools he uses to measure the performance of websites. The presentation is inspiring. It motivated me to learn more about the solutions I use and try to really understand what happens under the hood. Rasmus has proven that that is the only way to get good optimization results.

The presentation also made me think about some things regarding the CakePHP framework, specially their concern on making the new versions of the framework backwards compatible with older versions of PHP and not using the PHP 5.3 features. I searched the web for some more “aggressive” frameworks and I really liked the Recess Framework. It’s sad to see that its development is stalled =/
