I’m unhappy with our current CDN because global users still see slow loads

If global users are still seeing slow loads, the issue may not be just the CDN provider—it could be configuration, cache strategy, origin latency, or how assets are served.

A practical way to improve performance is to:

1. Measure where the slowness is

   • Check TTFB, cache hit ratio, and regional latency.
   • Compare performance by geography and device type.

2. Verify CDN caching

   • Ensure static assets have long cache lifetimes.
   • Use proper cache headers and versioned filenames.

3. Reduce origin dependence

   • Make sure the CDN can serve most requests from edge cache.
   • Avoid cache-busting on assets unless necessary.

4. Optimize asset delivery

   • Compress images, minify JS/CSS, and use modern formats like WebP/AVIF.
   • Split large bundles and lazy-load noncritical content.

5. Check DNS and edge coverage

   • Some CDNs have stronger POP coverage in certain regions.
   • Global performance can vary significantly by provider.

6. Inspect the app itself

   • Slow backend responses can make a CDN look ineffective.
   • Use edge caching, server-side rendering improvements, or API response caching if applicable.

7. Consider a different CDN only if needed

   • If you already have good caching and optimization but still see poor regional performance, switching providers may help.
   • Compare POP presence, latency in target regions, pricing, and features like image optimization and edge compute.

If you want, I can help you:

• diagnose whether the CDN is actually the bottleneck,
• compare CDN providers for your target regions,
• or build a step-by-step migration plan.
