How this test works
One selected Globalping probe makes a restricted HTTP or HTTPS request without custom headers, cookies, credentials, or request bodies.
SYNTHETIC HTTP TIMING
Measure DNS, TCP, TLS, first byte and download timing.
One selected Globalping probe makes a restricted HTTP or HTTPS request without custom headers, cookies, credentials, or request bodies.
Use DNS, TCP, TLS, first-byte, and total time to locate delay. Redirect responses describe only the returned hop, not a browser waterfall.
Time to first byte: the delay between sending the request and receiving the first byte of the response. Under 200 ms in the same region is good; over 500 ms usually means server work is the bottleneck.
No. This is a server-side timing from a single remote probe. PageSpeed Insights runs a real browser and measures Core Web Vitals, including rendering. Use each for what it's good at: server health here, front-end performance there.
Distance adds latency to every round trip, and without a CDN the routing may be suboptimal. Run the test from each region to separate unavoidable distance from fixable problems.
Minimally. TLS 1.3 costs one extra round trip at connection time, a few milliseconds on healthy paths, and the security gain is worth it. The exception is a misconfigured or CPU-bound TLS setup, where it genuinely slows things down.
Measured in the same region on a healthy site: DNS under 50 ms, TCP and TLS under 50 ms each, first byte under 200 ms, and a total time proportional to the page size. Absolute numbers depend on distance and page weight.
