Most performance problems trace back to the same root cause — assets still loading from a single origin server. Here are the six delivery problems we fix with every CDN engagement.
High TTFB for International Visitors
When your origin server is in one region, visitors from other continents experience 800ms+ TTFB before a single byte loads — losing them before the page even starts to render.
All Assets Served from a Single Origin
Images, CSS, and JavaScript all routed through one server causes latency spikes, bandwidth overload, and poor performance for anyone outside your hosting region.
No Cache-Control Headers Set Properly
Without correct cache headers, browsers and CDN edge nodes cannot cache your assets — every page load re-fetches the same files from origin, burning time and bandwidth.
CDN Misconfiguration Delivering Stale Content
A misconfigured CDN can serve outdated pages or files long after you publish updates — eroding trust with visitors who see old prices, removed products, or broken layouts.
Images and JS Not Being Cached at Edge
Large images and JavaScript bundles loading from origin on every request are the single biggest cause of slow LCP and high TTFB — even on otherwise fast hosting.
Core Web Vitals Failing Due to Slow Asset Delivery
Google measures real-user field data. If your assets are slow to reach users globally, LCP and FCP scores suffer regardless of how well the server itself performs.
