Network Investigation
A good speed test does not always mean websites will load quickly.
Website performance depends on DNS resolution, CDN routing, server response times, latency, packet loss and overall route quality, not just bandwidth.
A normal speed test only shows that your connection can transfer data at a certain rate.
Website loading also depends on name resolution, route quality, server responsiveness and connection stability.
Speed tests usually connect to optimized testing servers.
Loading a website involves DNS lookups, connection setup, content requests, images, scripts and multiple server responses.
Different websites use different server locations, CDN providers and network architectures.
Even when your connection is stable, the destination website may have slower infrastructure or less efficient routing.
Do not focus only on download speed.
Check DNS response times, latency, packet loss, route quality, server responsiveness and where the website is hosted.
The browsing experience depends on the entire request path, not just available bandwidth.
Reliable DNS resolution, low latency and stable routing often matter more than an impressive speed-test number.
