If you’re looking for a performance-driven WordPress theme, this guide will break down why GeneratePress and Astra are leading choices for creating fast, SEO-friendly, and highly customizable websites.
What Makes a WordPress Theme Fast?
A WordPress theme consists of four core components:
- HTML: Should be clean and minimal. Overcomplicated HTML structures can negatively impact performance.
- CSS: The more complex and bloated the CSS, the slower the site loads. Clean, optimized CSS is key.
- JavaScript: Many themes rely on jQuery, which adds unnecessary weight. A fast theme should use vanilla JavaScript and keep scripts to a minimum.
- PHP: The theme’s PHP code determines how efficiently it communicates with WordPress. Poorly optimized PHP can slow down the entire site.
The goal of a high-performance WordPress theme is to reduce bloat, optimize code execution, and minimize HTTP requests to ensure faster page loads and improved server efficiency.
GeneratePress: A Lightweight and Performance-Focused WordPress Theme

GeneratePress excels in this aspect:
- Main stylesheet size: 5.2KB
- Main JavaScript file: 2.3KB
- Total HTTP requests from the theme: 2 (weighing only 7.5KB)
