I just finished reading the book Pro PHP Refactoring by Franvesco Trucchia and Jacopo Romei. The book itself should be refactored - it's not pro at all. The book is an attempt to take the guidelines from the famous "Refactoring, Improving the Design of Existing Code" by Martin Fowler and turn them into PHP refactoring principles. https://unixsheikh.com/articles/the-book-pro-php-refactoring.html

This is a benchmark test of the performance of MySQL Cache. The test was performed on an Intel P4 1.7 Ghz with 1036028 kB of memory over a private LAN. The server runs MySQL 5.0.51a and PHP 5.3.3 on a standard Debian installation. Between each change of settings all related processes was restarted. Since Debian Squeeze the MySQL Cache is enabled by default. https://unixsheikh.com/articles/benchmark-2-mysql-cache.html
This is a benchmark test of the loading speed of dynamic pages vs. static pages vs. pages stored in Memchached using PHP. The test was performed on an Intel P4 1.7 Ghz with 1036028 kB of memory over a privat LAN. The server runs MySQL 5.0.51a and PHP 5.3.3 on a standard Debian installation. Between each change of settings all related processes was restarted. https://unixsheikh.com/articles/benchmark-1-dynamic-pages-vs-static-pages-vs-memcached.html
This is a benchmark test of the performance of PHP with and without APC (Alternative PHP Cache). The test was performed on an Intel P4 1.7 Ghz with 1036028 kB of memory over a private LAN. The server runs PHP 5.3.3 on a standard Debian installation. Between each change of settings all related processes was restarted. https://unixsheikh.com/articles/benchmark-3-the-alternative-php-cache-apc.html
