Question 1

How does SpeedFox test internet speed?

Accepted Answer

SpeedFox streams HTTP chunk payloads directly from your browser to edge test servers. It measures latency (ping), variation in response times (jitter), and true throughput across warm-up and measurement windows.

Question 2

Why does my speed test result vary?

Accepted Answer

Speed tests fluctuate based on Wi-Fi signal strength, background downloads, local network congestion, device performance, or VPN client routing.

Question 3

What is a good ping for gaming?

Accepted Answer

For online gaming, a ping under 30ms is considered optimal. Pings between 30ms and 50ms are good, while pings above 100ms may cause noticeable lag.

Question 4

What is jitter and why does it matter?

Accepted Answer

Jitter measures the stability of your latency over time. Low jitter (under 5ms) ensures smooth video calls and online gaming without sudden stutters.

Question 5

Are browser-based speed tests accurate?

Accepted Answer

Yes! By using multi-stream chunk requests, cache-busting headers, and warm-up windows to bypass TCP slow-start artifacts, browser tests provide accurate real-world performance metrics.

Question 6

Does VPN affect my speed test results?

Accepted Answer

Yes. VPNs route your internet traffic through encrypted servers, which adds latency and can reduce throughput depending on the VPN provider server load.
