Overview
This tool uses Cloudflare speed nodes to measure download and upload speed, latency, and jitter, then provides a quality score and optimization hints for office checks, home broadband review, and pre-call/game validation.
Key Features
- Download test: estimate downstream bandwidth from multiple sample downloads on Cloudflare nodes
- Upload test: estimate upstream bandwidth through sample uploads to Cloudflare nodes
- Latency and jitter test: evaluate responsiveness and real-time stability
- Quality score: calculate overall score from download, upload, latency, and jitter
- History records: store recent results for trend comparison
FAQ
Why can upload speed be lower?
Upstream bandwidth is often lower than downstream and is more sensitive to sync, backup, and router load.
Where are test requests sent?
Test requests are sent to Cloudflare speed nodes to measure download, upload, latency, and jitter.
Why do results fluctuate?
Congestion, Wi-Fi interference, background traffic, and ISP scheduling can all change instant results.
How can I get more stable results?
Close heavy network apps, stay near your router or use cable, and run tests at different times.
