# Performance Tips

- **The Page Designer loads on demand.** It only initialises when you navigate to it, keeping the rest of the Blackthorn app fast. Expect a brief load on first open.
- **Layouts are cached** to speed up public page loads. If your published page looks stale after saving, go to **Site Settings → Page Cache → Clear Page Cache** to force an immediate refresh.
- **Optimize images before uploading.** Compress large files and use appropriate dimensions before adding them to the Asset Library. While images are auto-optimized on upload, starting with a well-sized source file produces the best results.
