What do download and upload speeds mean?

Download speed measures how fast data can be transferred from the internet to your device (streaming, browsing, downloading files). Upload speed measures how fast data goes from your device to the internet (video calls, uploading files, cloud backups).

What is latency (ping)?

Latency, or ping, measures the time it takes for data to travel from your device to a server and back, in milliseconds. Lower latency means more responsive connections, which is important for gaming, video calls, and real-time applications.

Jitter measures the variation in latency over time. High jitter can cause choppy video calls, lag spikes in games, and inconsistent connection quality even if your average speed is good.

Why might my speeds be slower than expected?

Speed can be affected by many factors: Wi-Fi interference, network congestion, distance from router, VPN usage, other devices using bandwidth, time of day, and your ISP's actual provisioned speeds. Try testing with a wired connection for most accurate results.

What speeds do I need for common activities?

For HD streaming: 5-10 Mbps. For 4K streaming: 25+ Mbps. For video calls: 3-10 Mbps. For online gaming: 10+ Mbps with low latency (<50ms). For working from home: 25+ Mbps. These are per-user recommendations.

Is my data stored or logged?

No, speed test results are only stored locally in your browser for the current session. We don't log or store your test results on our servers.

Why run the test multiple times?

Network speeds can fluctuate. Running multiple tests helps identify your typical speed range and whether you're experiencing consistent or variable performance. The test history feature lets you compare results.

Speed Guide

Excellent (100+ Mbps)

4K/8K streaming, large file transfers, multiple users, smart home devices

Good (25-100 Mbps)

HD/4K streaming, video calls, gaming, remote work

Fair (10-25 Mbps)

HD streaming, video calls, light gaming, web browsing

Slow (<10 Mbps)

Basic browsing, SD streaming, may struggle with video calls

Understanding Latency

Latency Ratings

<20ms: Excellent - Ideal for competitive gaming
20-50ms: Good - Great for most online activities
50-100ms: Fair - Acceptable for casual gaming
>100ms: Poor - Noticeable lag in real-time apps

What Affects Latency?

- Physical distance to servers
- Number of network hops
- Network congestion
- VPN/proxy usage
- ISP routing efficiency
