Memcached

Implementing Full-Page caching with Nginx and PHP

This is part two in my caching series. Part one covered the concept behind the full page caching as well as potential problems to keep in mind. This part will focus on implementing the concept in actual PHP code. By the end of this you’ll have a working implementation that can cache full pages and invalidate them intelligently when an update happens.

12,000 Requests per second with Nginx, PHP and Memcached

Caching in PHP is usually done on a per-object basis, people will cache a query or some CPU intensive calculations to prevent redoing these CPU intensive operations. This can get you a long way. I have an old site which uses this method and gets 105 requests per second on really old hardware. The method I propose will net you a solid 12,000 requests per second.
