- Internet connection
Download speed: Fetches a 1 MB test file from OVH and Cloudflare, measures bytes/second, reports Mbps. Also shows TTFB (time to first byte).
Latency: Sends 3 HTTP HEAD requests to Cloudflare (1.1.1.1), Google (8.8.8.8), GitHub, and Fastly CDN. Reports the average round-trip time.
All measurements run in-process with BCL HttpClient — no shell commands, no external tools.
