Note that breaking BC is not only about performance - one your build is not the same as mainstream PHP, you can't use any binary extension which would do anything non-performance-related - like interfacing some external system/library, debugging, profiling, testing, security and so on. Any commercial module won't be available for the user of this switch, and all open-source modules one'd have to build by oneself, which may be serious maintenance issue. I know there are a bunch of companies that compile PHP with their own options but still use commercial modules, including both performance and non-performance ones. They couldn't use this compile switch. -- Stanislav Malyshev, Zend Software Architect stas@zend.com http://www.zend.com/ (408)253-8829 MSN: stas@zend.com
