To support hosting multiple developer sandboxes on a single host as well as reduce the overhead of deploying multiple code versions in production, two webapps should be able to share the internal representation of a PHP file that is identical in both. Otherwise a large PHP app with multiple instances will chew through PermGen space like crazy with lots of identical class files. This will also presumably make it cheaper to restart a particular webapp (e.g., due to a signature change on a Java class) since the compiled PHP files won't have to be reloaded. |
