Load balancing – LVSKB

Posted on by

In computing, load balancing is a technique used to spread work load among many processes, computers, networks, disks or other resources, so that no single resource is overloaded.

Load balancing can also be considered as distributing items into buckets:

  • data to memory locations
  • files to disks
  • tasks to processors
  • packets to network interfaces
  • requests to servers

Its goal is even distribution.

PHP Template Engine | Smarty.

Crash course here.

Smarty also has built-in caching capabilities to help speed up the page rendering. A copy of the template output is stored in a text file, then that is displayed upon subsequent calls to the request instead of dynamically rendering the page each time.

You can also leave parts of a page dynamic just by marking them as nocache.
