Hardware and performance

The eaccelerator troubleshooting document (http://eaccelerator.net/wiki/TroubleShooting#Veryfiing) says the below. Does moodle use scripts encoded with Zend Encoder? I assume not and that Zend Optimizer won't help...but thought I'd check to confirm.

Zend Optimizer ¶

eAccelerator has been reported to work with Zend Optimizer's loader. Zend Optimizer must be installed after eAccelerator in php.ini so it's loaded after eAccelerator. If you don't use scripts encoded with Zend Encoder then we do not recommend installing Zend Optimizer with eAccelerator, and it won't give you any extra performance.
