HTTP Latency Test · At a glance
Quick answer: Measure HTTP round-trip time to this website, including server processing. This is HTTP round-trip time, including browser, connection and server processing.
HTTP Latency Test
The test loads when you open it. Device access is requested only after you choose to start.
Detailed guide
How to use this tool
- Start repeated requests to this website and keep other transfers quiet.
- Read the median and variation across the sample.
Input
Requests only to this website
Browser requirement
PHP endpoint; HTTPS hosting
Processing
Requests to this website; hosting can affect the result
How it works and what the result means
Latency is an HTTP round trip including TLS, server processing and browser overhead. Throughput is to this host and may be constrained by hosting, compression, caching or buffers.
Reading the result
This is HTTP round-trip time, including browser, connection and server processing. It is not ICMP ping to a game server.
What to check next
The PHP endpoint must be enabled on hosting. A static preview cannot execute it and should report unavailability instead of a fabricated number.
This is not ICMP ping, UDP packet-loss measurement or a test of every internet route. The PHP endpoint must be enabled on the host. Timeouts are request failures, not measured network packet loss.
Frequently asked questions
Can I use this to measure ping to any server?
No. Requests target this website. Different destinations and protocols can have different latency and routing.
How do I start the HTTP Latency Test?
Start a short test to this website. Keep other downloads quiet when measuring baseline latency or throughput.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
