Zend Accelerator

The Zend Accelerator is a server-side caching program designed to speed up PHP based Web sites dramatically. The Zend Accelerator was engineered to handle the scripts that dynamic Web sites depend on. Integrated with the Zend Engine, the ‘kernel' of PHP 4.0, the Accelerator applies a variety of optimizations and advanced caching techniques to dramatically improve the performance of PHP-based dynamic Web sites. The Zend Accelerator typically increases the number of requests that can be handled per second by a factor of 3. It also trims latency to near zero. The Zend Accelerator incorporates a built in performance monitor that enables system administrators to measure the speedup experienced by actual site visitors in real-time.
