Network Speed Test#

Measure download, upload, and latency with zero dependencies.

Commands#

All commands use scripts/speed_test.py.

Run All Tests#

bash

python3 scripts/speed_test.py --all
python3 scripts/speed_test.py --all --json

Individual Tests#

bash

python3 scripts/speed_test.py --download
python3 scripts/speed_test.py --upload
python3 scripts/speed_test.py --latency

Custom Test Size#

bash

python3 scripts/speed_test.py --download --size 25   # 25 MB download test
python3 scripts/speed_test.py --all --size 50         # 50 MB download, 25 MB upload

JSON Output#

bash

python3 scripts/speed_test.py --all --json

Returns structured JSON with timestamp, latency stats (avg/min/max/jitter per host), download speed (Mbps), and upload speed (Mbps).

Latency Targets#

Tests TCP connection latency to Cloudflare DNS (1.1.1.1), Google DNS (8.8.8.8), and Quad9 (9.9.9.9). Reports average, min, max, and jitter for each.

Notes#

• Download uses Cloudflare speed test endpoint
• Upload uses Cloudflare speed test endpoint
• Default test size: 10 MB download, 5 MB upload
• No API keys or accounts required
