Pages with dozens of blocks load slowly or crash the editor.
Too Many Blocks Make Editor Unusable
Key Points: Long pages with dozens of Gutenberg blocks become sluggish, freeze, or crash during editing.
You build a beautiful homepage with block after block… and then the editor starts crawling. Soon, it freezes entirely. You’re building a page — not launching Photoshop.
📉 Causes
- Overuse of columns, nested containers, or animation-heavy blocks
- Memory limitations in the browser for rendering block tree
- Plugin-generated blocks with large settings payloads
🛠️ Fix Suggestions
- Split long pages into smaller ones or modular templates
- Remove or simplify unnecessary animations and effects
- Use patterns instead of duplicating blocks manually
⚠️ Performance Tip
The more blocks you load, the more memory your browser eats — minimalism is performance-friendly.
