When reading on Facebook developing notes, which uses PHP among other languages, I stumbled on an interesting article about memcache. Memcache is a way to cache objects in memory, and after reading a blog post about php and memcache I realised that this little neat cache tool can be magick if you run a website with heavy load.
Definitely something to think on when designing a new web site. Especially when Zend Framework supports memcache!
