PING (Latency): Round-trip time to server. Lower = better response time.
JITTER: Variation between ping samples. Measures stability. High jitter = lag spikes.
Use Cases:
What is ping and why does it matter? Ping measures the round-trip latency between your device and a server. Lower ping is better for real-time activities like gaming and video calls.
What is jitter? Jitter is the variation between ping samples. Even if your average ping looks fine, high jitter can cause stutters, rubber-banding, or choppy calls.
What is a "good" ping and jitter? As a rough guide: competitive gaming typically wants ping <20ms and jitter <5ms, while casual use can tolerate higher. The best target depends on your game/server and your connection type.
Why are my results different each time? Network congestion, Wi-Fi interference, background downloads, and ISP routing changes can all shift latency and jitter. Run a few tests at different times to spot patterns.
