But often the server administrator has little control over the application itself because it's written by someone else. This series of three articles discusses many of the server configuration items that can make or break an application's performance. This second article focuses on steps you can take to optimize Apache and PHP. Linux, Apache, MySQL, and PHP (or Perl) form the basis of the LAMP architecture for Web applications.
