Geschwindigkeitstest
Measure your internet connection speed using Cloudflare's global network.
Understanding Your Results
Download speed measures how fast data travels from the internet to your device. It affects streaming, web browsing, and file downloads. Most households need 25-100 Mbps.
Upload speed measures how fast data travels from your device to the internet. It affects video calls, file uploads, and cloud backups. Typically 5-10x slower than download on most connections.
Latency (ping) measures the delay in milliseconds between your device and the server. Lower is better. Under 20ms is excellent, 20-50ms is good, over 100ms causes noticeable lag in video calls and gaming.
This test uses Cloudflare's global network (300+ cities worldwide) to measure your connection. Results represent your speed to the nearest Cloudflare server, which approximates real-world browsing performance.
For the most accurate results: close other tabs, pause downloads, and test on a wired connection rather than Wi-Fi. Run the test multiple times and average the results.
FAQ
How accurate is this speed test?
This test uses Cloudflare's global network in 300+ cities. Results may vary based on server proximity, network congestion, and your ISP's peering.
Why is my speed slower than my plan?
ISP plans advertise "up to" speeds. Actual speeds depend on network congestion, Wi-Fi interference, distance from your router, and device count.
Does VPN affect speed?
Yes. VPNs add encryption overhead and route traffic through additional servers. A good VPN typically reduces speeds by 10-30%.
