Differences between Turbo Web Hosting servers and Drive Web Hosting servers

From a user perspective, A2 Hosting's Turbo Boost and Turbo Max Web Hosting servers behave almost identically to our Drive Web Hosting servers. However, there are a few differences between A2 Hosting's Turbo Boost and Turbo Max Web Hosting and Drive Web Hosting servers that impact web developers.

The Turbo Boost and Turbo Max Web Hosting servers:

• compile .htaccess files to make speed improvements. Any changes to .htaccess files are immediately re-compiled.
• have their own PHP API that provides speed improvements over FastCGI and PHP-FPM (FastCGI Process Manager).
• servers do not need to create a worker process as the user to serve static files. Servers only create a worker process for PHP scripts, which results in faster performance.
• APC (Alternative PHP Cache) is enabled by default. Accounts are allocated 16 MB of APC memory.
• have double the physical memory allocated.
• have a built-in caching engine; however, caching is disabled by default. To enable caching, you must use an .htaccess file. For information about how to do this, please see this article. 
• PHP configuration settings are changed using cPanel instead of php.ini files. You can also change the PHP version using cPanel. For information about how to do this, please see this article.
• do not support Ruby-based or Python-based web applications, including Rails and Django.
