⚡ CDN Performance Calculator

A Content Delivery Network (CDN) is a distributed network of servers located worldwide that cache and deliver your website content from the server closest to each visitor. This reduces latency by 60-85% on average, as data travels shorter distances. For example, a visitor from Tokyo accessing a Frankfurt-hosted site experiences 672ms latency without CDN, but only ~100ms with a CDN serving from Tokyo. This improvement directly translates to faster page loads, better user experience, and higher conversion rates.

Our CDN calculator is based on real production data from 578,382 network checks across 30 global locations, measured continuously from our Frankfurt monitoring infrastructure. The latency improvements (60-85% reduction) are conservative estimates based on actual CDN performance data from major providers like Cloudflare, Bunny CDN, and AWS CloudFront. Individual results may vary based on content type, caching strategy, and specific CDN configuration.

Research from Amazon, Google, and Walmart shows that every 100ms of latency reduces conversion rates by approximately 1%. For e-commerce sites, this is significant: if your current latency is 500ms and a CDN reduces it to 100ms (400ms improvement), you could see a 4% increase in conversions. For a site with 10,000 monthly visitors and a 2% baseline conversion rate, that's an additional 8 conversions per month (from 200 to 208).

The best CDN depends on your needs and budget. For most websites, we recommend Bunny CDN due to its excellent price-to-performance ratio (from $1/month), 114 global locations, and simple setup. Cloudflare offers a generous free tier with basic features. AWS CloudFront and Fastly are better for enterprise needs with advanced requirements. Our calculator shows expected improvements that are achievable with any major CDN provider, as the performance gains primarily come from geographic distribution rather than specific technology.

To find your traffic distribution: 1) Log into Google Analytics, 2) Go to Audience → Geo → Location, 3) Set date range to last 30-90 days, 4) Group countries by continent (North America, Europe, Asia, etc.), 5) Calculate percentage for each region. If you don't have analytics yet, use general estimates based on your target market. For global sites, a common distribution is: 40% North America, 30% Europe, 20% Asia, 10% Other. The calculator works with any distribution you provide.

Yes! CDNs work with any hosting provider (shared, VPS, dedicated, cloud). A CDN sits in front of your origin server and caches static content (images, CSS, JavaScript, fonts). Dynamic content still comes from your origin server, but the CDN handles the heavy lifting of static asset delivery. Setup typically involves: 1) Signing up for a CDN, 2) Updating DNS records or installing a plugin (WordPress/Shopify), 3) Configuring cache rules. Most CDNs offer one-click integrations with popular platforms.
