It measures the full connection waterfall for a URL, DNS lookup, TCP connect, TLS handshake, Time To First Byte, and HTML transfer, from Novaverb's Germany probe or selected community probes placed across world regions.

The speed check runs only from Germany. This performance test can additionally run from community probes in multiple world regions, letting you compare connection timing across geographies rather than from one fixed vantage point.

No. Each number reflects network and server connection timing only. It does not run a browser, so it cannot measure Largest Contentful Paint, layout shift, interactivity, JavaScript execution, or anything about how the page visually renders.

It is the ordered breakdown of a request: DNS resolves the hostname, TCP establishes the connection, TLS negotiates encryption, TTFB captures server wait, and HTML transfer downloads the initial document. Each stage exposes where time is spent.

Each probe is a separate physical location, so distance to your server and CDN edge changes DNS, connection, and transfer times. Regions far from your hosting or without nearby edge nodes will consistently show higher latency.

Hãy nhắm tới kết quả nằm trong dải tốt ở các thị trường chính của bạn và các con số tương đối đồng đều ở nơi khác. Khoảng cách lớn giữa các khu vực thường cho thấy thiếu phủ CDN hoặc chỉ phục vụ từ origin cho người dùng ở xa, điều mà một mạng phân phối nội dung có thể san bằng.

Put a CDN in front of your origin so static assets and cached HTML serve from edge nodes near users. Also enable modern protocols and caching so far-away regions are not paying full origin round-trips.

Treat each number as a single sample from one probe at one moment, subject to transient network conditions. Run repeated checks and compare trends across regions rather than drawing conclusions from any isolated measurement.

Not exactly. Probes approximate network paths but are not your actual visitors on their devices, browsers, and connections. Use this for comparing server and network delivery across regions, and pair it with field data for true real-user performance.

Distance and routing can change connection and first-byte time. Regional probes help locate delivery gaps, but they do not measure browser rendering, real users or search-engine behavior.
