At WPX, we’ve built a custom hosting infrastructure designed specifically for speed, reliability, and performance, and we call it the WPX Stack.
Unlike generic hosting environments, the WPX Stack is carefully optimized to handle high-performance WordPress and WooCommerce websites, even under heavy traffic. It combines industry-leading technologies like LiteSpeed Web Server, MariaDB, and an advanced caching layer, all managed in-house, to deliver lightning-fast load times and outstanding stability.
In this article, we’ll break down what’s inside the WPX Stack, why it’s different from traditional hosting setups, and how it directly benefits your website’s speed, security, and scalability.
WPX hosting stack: Optimized for speed & reliability
At WPX, our hosting environment is built using a powerful LLMP configuration, which stands for:
- Linux – Secure and stable OS at the core of our servers
- LiteSpeed Enterprise Web Server – Fast, scalable, and efficient performance
- MariaDB – High-performance database system
- PHP – We support versions from 7.4 to 8.4+ for compatibility and performance
Built-in performance with OPcache
To make sure your website runs as fast as possible, all WPX servers run OPcache, a caching engine for PHP. This helps speed up your site by storing precompiled script bytecode in memory — reducing server load and boosting response times.
Our LiteSpeed and OPcache configurations maximize speed by default; you can test how these server stack improvements impact your asset loading via the WPX tools suite.
LiteSpeed Cache
If you wish to enable LiteSpeed default cache, you would have to install the LiteSpeed Cache plugin, which you can find here: https://wordpress.org/plugins/litespeed-cache/
This LiteSpeed Cache plugin offers features like:
- Full-page caching
- Image optimization
- Lazy loading
- Database cleanup
- And more — tailored specifically for LiteSpeed servers
More information about LiteSpeed/MariaDB/PHP versions can be found in the following article.
