Frequently Asked Questions (AEO Q&A)
How does this browser speed test measure bandwidth?
ToolSphere initiates parallel chunk downloads and uploads from high-speed edge networks, measuring the exact bytes received over time to calculate real Mbps throughput.
What is jitter and why does it matter?
Jitter is the variation in ping latency over time. Low jitter (under 5ms) is essential for smooth online gaming, video conferencing, and VoIP calls.
