1.9. Performance

ZF3 provides the following features to ensure its performance is acceptable:

• Lazy class autoloading. Classes are loaded once needed. You don't have to write require_once for each class you want to load. Instead, the framework automatically discovers your classes using the autoloader feature.

• Efficient service and plugin loading. In ZF3, classes are instantiated only when they really need to. This is achieved through service manager (the central container for services of your application).

• Support of caching. PHP has several caching extensions (like Memcached) that can be used to speed-up ZF3-based websites. Caching saves frequently used data to memory to speed-up data retrieval.
