Boost site perormance in cloudflare
Disclaimer: The performance improvements and results discussed in this post are based on Glowupshot's specific setup, infrastructure, and use case. Your results may vary depending on your application architecture, content type, and implementation approach.
I was using and dealing with Cloudflare on a daily basis for 4 years. Recently, I have deployed my SaaS Glowupshot.com fully into it without using any external services. Here are 8 tips for boosting website performance.
For Images:
Enable Polish for Images Turn on Polish (Pro plan) with Lossy + WebP. It cuts image sizes by 48% automatically. No code changes are needed.
Mirage for Mobile Images
Perfect for slow connections. It lazy loads images on mobile devices. Enable it in Speed > Optimization.
For Content:
- NEW: Cloudflare Fonts (Beta)
I just enabled this! It reduces external font requests by serving Google Fonts from Cloudflare's edge. Better privacy + faster loads.
- Rocket Loader for JavaScript
It improves paint time by loading JS asynchronously. Great for sites with heavy scripts. One toggle = instant boost.
For Caching:
- Caching
Cloudflare caching is a massive and tricky product. If your origin server is behind Cloudflare, enable Cache Reserve or Tiered Cache, depending on your case.
I use Cloudflare Workers, which cache on the edge by default.
Computing:
- Worker
I use Worker + D1 at the edge = 31 ms request duration. I'm not advocating for Worker, but combining compute and database boosts performance. I'd use KV, R2, and Durable Objects if needed.
Proxy:
- Advanced use case for Worker as a subdirectory
If you have a blog or docs under a subdomain like https://glowupshot.com or http://docs.example.com, use Worker as a reverse proxy. This allows http://glowupshot.com/blog to function as a normal page, boosting your SEO. - Worker for streaming responses from the origin server
Use a Worker as a proxy to request from the origin server and stream the response.
