Why CDN Choice Matters More Than Your Upload Speed
Once your content leaves your server, your upload speed is irrelevant. What determines your viewer's experience is the CDN's ability to cache your content close to them and serve it quickly. A poorly chosen CDN can make 4K video files feel slow even when your origin server has 10 Gbps upload capacity.
CDN Benchmark Results (Average Across All Regions)
- Cloudflare CDN (Free/Pro tier): Best median TTFB (42ms globally). Excellent cache hit rates. Free tier is genuinely production-ready for most creators. Full network of 300+ PoPs. Winner for global performance at no cost.
- BunnyCDN: Best price-to-performance ratio. $0.01/GB in US/EU (vs Cloudflare's $0.08/GB on paid tiers). 90ms median TTFB — slightly higher than Cloudflare but excellent for the price. Fastest in South America and Middle East regions where Cloudflare's free tier PoP coverage thins. Winner for budget-conscious creators with large video catalogs.
- AWS CloudFront: 68ms median TTFB. Excellent reliability (99.99% SLA). Best for creators already in the AWS ecosystem. At $0.085/GB in US, significantly more expensive than BunnyCDN. Overkill for most individual creators unless you need AWS IAM integration. Best for enterprise/professional studios.
- Fastly: 55ms median TTFB. Excellent but complex configuration (VCL-based config). Designed for developers more than creators. Pricing comparable to AWS at high volumes. Best for technical creators who need custom edge logic.
Practical Recommendation by Creator Type
- Small creator (under 1 TB/month): Cloudflare Free. Zero cost, excellent performance globally.
- Mid-size creator (1–50 TB/month): BunnyCDN. $0.01/GB beats every competitor at this volume.
- Large creator / video platform (50+ TB/month): Negotiate enterprise pricing with Cloudflare or BunnyCDN. Both offer volume discounts not listed publicly.
Speed Test Your CDN With DCSpeedTest Logic
The same principles that make DCSpeedTest accurate for ISP testing apply to CDN evaluation: test from multiple global locations, measure TTFB separately from throughput, and test during peak hours — not just midnight when CDN nodes are uncongested. Tools: cdnplanet.com and webpagetest.org allow multi-location CDN speed tests for free.
Multi-CDN Strategies for Larger Creators
Creators with genuinely global audiences sometimes run two CDNs simultaneously, routing by viewer region to whichever performs best locally — a more complex setup, but one that avoids being limited by any single CDN's weaker regions, at the cost of added configuration overhead.
CDN Choice for Live Streaming vs On-Demand Video
Live streaming has stricter latency requirements than on-demand delivery, since viewers notice delay in real-time interaction — a CDN's live-streaming-specific infrastructure (not just its general file-delivery speed) is worth checking separately if live content is a meaningful part of your output.
Origin Server Location Still Matters
A CDN caches content close to viewers, but the first time a piece of content is requested in a given region, it still pulls from your origin server — for creators with a global audience and frequently updated content, origin server location and upload speed to it remain relevant even with an excellent CDN in front.
