Ping & Latency Test

Internet & NetworkPopular

Measure HTTP network round-trip latency, jitter, and connection stability to global server nodes in real time.

Round Trip Time (RTT) = T_response - T_request; Jitter = Mean(|RTT_i - RTT_{i-1}|)

Understanding Your Results

Under 30ms = Excellent (Competitive Gaming, Real-time audio). 30–70ms = Good (Smooth 4K streaming, Zoom calls). 70–150ms = Acceptable. >150ms = Noticeable lag. Jitter indicates connection consistency; jitter > 15ms causes voice stutters.

Practical Guidance & Next Steps

If ping is high or jitter is > 20ms, switch from 2.4GHz WiFi to 5GHz WiFi or a wired Ethernet cable. Check if background downloads or VPN routing are increasing latency.

What is this?

A browser-based latency benchmarker that measures HTTP round-trip time (RTT) to global edge endpoints using `performance.now()` precision timing.

How does it work?

1. Sends lightweight requests to high-speed CDN edge servers. 2. Computes the exact round-trip response time in milliseconds. 3. Calculates jitter, minimum, average, and maximum latency.

Why use it?

Diagnose sluggish browsing, detect WiFi packet jitter before competitive gaming, or verify VPN overhead with precise timing metrics.

Technical Scope & Calculation Limitations

Browser-based ping measures HTTP application-layer round-trip time via performance.now(). It includes TLS/TCP overhead and will be slightly higher than raw ICMP ping in command line terminal.

Frequently Asked Questions

Under 30ms is excellent, 30-70ms is good for browsing and gaming, 70-150ms is acceptable, and over 150ms will feel noticeably laggy.
