Differences between Turbo Web Hosting servers and non-Turbo Web Hosting servers

From a user perspective, A2 Hosting's Turbo Velocity and Turbo Nitro Web Hosting servers behave almost identically to our non-Turbo (Ignite and Accel) Web Hosting servers. However, there are a few differences between A2 Hosting's Turbo Velocity and Turbo Nitro Web Hosting and non-Turbo Web Hosting servers that may impact web developers.

The Turbo Velocity and Turbo Nitro 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).
• 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.
• have APC (Alternative PHP Cache) enabled by default. Accounts are allocated 16 MB of APC memory.
• have double the physical memory allocated.
• have NVMe SSD storage for faster read/write speeds.
• have AMD Ryzen 9 CPUs for faster performance.
• 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. 
• use cPanel instead of php.ini files for managing PHP configuration settings. 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.
