If you’ve been around PHP for a while, you’ve probably heard about APC, the Alternative PHP Cache. Adding APC to an application usually results in improved application response times, reduced server load and happier users. This article will introduce you to APC and guide you through the process of integrating it with your PHP application.

Zend and Acquia have jointly released a new white paper entitled: Optimizing Drupal Performance – Benchmark Results.

This paper presents the results of performance benchmarks for comparing several common PHP runtime environments and configurations. The application used for benchmarking is Drupal, the open source social publishing platform.

Tested runtime environments included plain PHP, Zend Server (www.zend.com/products/server), and open-source optimizers, such as APC and WinCache.

p. We’ve talked about this before, but not recently. Quentin Zervaas has posted a nice tutorial on how to use APC, PHP 5 and prototype.js to build a file upload progress bar.
