PHP Speedy is a script that you can install on your web server to automatically speed up the download time of your web pages. Here’s an example, from a test page:

Here is my compilation of tips on how to optimise Apache on Linux for PHP and CGI programs.

This tutorial takes a practical, example-based approach to implementing those rules. It's targeted towards web developers with a small budget, who are most likely using shared hosting, and working under the various restrictions that come with such a setup. Shared hosts make it harder to play with Apache configuration -- sometimes it's even impossible -- so we'll take a look at what you can do, given certain common restrictions, and assuming your host runs PHP and Apache.

Over the summer I wrote a post called 5 Ways to Speed Up Your Site that went through some basic tips for getting your site to load faster. I mentioned enabling gzip compression in WordPress and using services that remove the whitespace from your CSS, effectively “compressing” it. Now, I’ll go a bit more in-depth with a simple, yet powerful, PHP method of compressing your CSS.

Applications using the LAMP (Linux®, Apache, MySQL, PHP/Perl) architecture are constantly being developed and deployed. 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. Many open source packages based on LAMP components are available to solve a variety of problems. As the load on an application increases, the bottlenecks in the underlying infrastructure become more apparent in the form of slow response to user requests. The previous article showed you how to tune the Linux system and covered the basics of LAMP and performance measurement. This article focuses on the Web server components, Apache and PHP.
