Achieving a perfect 100 PageSpeed score on both mobile and desktop for a WordPress site is extremely challenging, if not virtually impossible, for most real-world websites. Google itself states that aiming for 100% might not be the most practical goal, as it often requires a plaintext site with no images or styling.
Instead of focusing solely on a "100" score, it's more realistic and beneficial to aim for high scores (90+) and excellent Core Web Vitals, which Google prioritizes for user experience and SEO.
The themes that consistently rank high in speed and performance tests, making them the best candidates for achieving high PageSpeed scores, are generally lightweight, well-coded, and offer performance-focused features.

Important Considerations to Achieve High PageSpeed Scores (regardless of theme):
Even with the fastest themes, achieving truly high PageSpeed scores (especially near 100) requires comprehensive optimization beyond just the theme:
·
Reliable and Fast Hosting: This is paramount. A slow server will
negate any theme's speed advantages. Look for hosts optimized for WordPress
with good server response times (TTFB).
·
Image Optimization: Compress and resize images, use modern
formats like WebP, and implement lazy loading.
·
Caching: Use a robust caching plugin (e.g., WP Rocket, LiteSpeed
Cache, SG Optimizer) to serve cached versions of your pages.
·
Minification and Combination: Minify CSS, JavaScript, and HTML
files to reduce file sizes.
·
Content Delivery Network (CDN): Use a CDN to deliver your static
assets from servers closer to your users.
·
Remove Unused CSS/JS: Eliminate any unnecessary code that your
theme or plugins might be loading.
·
Optimized Fonts: Load fonts efficiently (e.g., use font-display:
swap).
·
Avoid Excessive Plugins: Every plugin adds overhead. Use only
essential plugins.
·
Clean Database: Regularly optimize your WordPress database.
· No
Render-Blocking Resources: Ensure critical CSS and JavaScript are loaded
efficiently to avoid blocking the initial rendering of the page.
