Magento maintenance script for IIS

Important Magento maintenance, now for IIS too: optimize the speed and performance of your Magento ecommerce webshop by carrying out important maintenance. Remove old MySQL database log files and Magento cache data on a regular basis.

Magento eCommerce Maintenance: Improve Webshop Speed & Performance

Clear Magento cache and MySQL log tables, perform regular Magento maintenance on IIS web servers for better performance. Magento Community Edition is a very popular ecommerce and webshop solution. And very bloated as we all know. Anywhere you run your Magento webshop, it’s important to perform maintenance. Carrying out maintenance on a regular basis optimizes Magento performance.

Two of such important Magento maintenance tasks are clearing out and emptying the MySQL database cache and log tables (such as log_visitor, log_url), and Magento’s file system cache directories in /var. Most scripts and solutions out there are for Linux- and Unix webservers only. I decided to modify a Magento maintenance script, to run on Windows Server and IIS too.

To optimize MySQL databases, it utilizes my MySQLi multi_query statement to optimize all MySQL tables in one statement.

Ask your hosting provider to schedule this script as a Windows Server scheduled task, for instance once a day, and you’ll notice a speed improvement of your Magento webshop. Next, add support for WinCache and your Magento webshop is very, very fast. Even on IIS!

Magento Maintenance Schedule URI’s

To perform automatic maintenance of your Magento webshop, to clear its cache, schedule the following URI’s:

• http://www.example.com/maintenance.php?clean=log
• http://www.example.com/maintenance.php?clean=var

for which you can use wget or curl.

This Magento maintenance script is tested with Magento 1.4.2.0 and Magento 1.7.0.2 without problems.
