Niall Kennedy is attending this year's OSCON as well, and brings us this new blog post covering another of Rasmus Lerdorf's talks covering the scaling web applications in PHP.

Rasmus Lerdorf led OSCON attendees through a series of optimizations for modern web applications using PHP at O'Reilly's Open Source conference today. Most programmers use default installations and configurations for their web applications and never really dig deep within their stack or their own code to optimize page load and latency. The full slides from Rasmus's talk are available online and I recorded audio of the entire session from the front row.

Niall also talks more about rich web applications, interaction models, and the use of http_load, the Valgrind emulation tool, prepared statements, the use of the APC, and the improved XML support included in PHP5.
