Chris Merrill has written up a case study measuring the load handling abilities of the Zend Optimizer with a default application - in this case, SugarCRM.

This article measures the performance impact of the Zend Optimizer on a real-world processor-bound PHP application (SugarCRM) under load. Our measure of performance is user capacity. We define that as the number of simultaneous users that the system can support while meeting the specified performance criteria. The performance criteria for this test require that all pages load within 6 seconds and no errors are encountered in the application.

The process is broken out into a few different sections including the methodology he used (including the software list, hardware used and configurations of both) and the results/analysis from running the test requests (such as page duration and server process use).

php|architect's Pro::PHP Podcast has posted their latest show fron this past Friday - an itnerview with Jacob Taylor of the SugarCRM project.

On June 16th, we interviewed SugarCRM's Chief Architect and Co-Founder, Jacob Taylor. Jacob defines, manages and develops the core Sugar Suite technology and has designed Sugar Suite to be one of the most conducive open source application projects for community development and contribution because of its modular architecture, high quality coding and superior scalability. Listen to Jacob explain why he chose PHP as the language to develop SugarCRM in, and how they are using it to make a huge impact in the CRM market.
