Single 512 MB POST over HTTP/2 was throttled by the per-stream h2 flow-control window, reading ~4x low. LibreSpeed uses parallel upload streams measured via XHR progress events, which amortizes the window limit (h2 must stay on for trojan-gRPC). - Vendor speedtest.js + speedtest_worker.js (LGPL) into assets - mtr-backend.py: ThreadingHTTPServer, /api/st/up upload sink, /api/st/getip; parallel streams need concurrent handling - nginx: speedtest locations without limit_req (limit_conn instead), ping answered by nginx directly, h2 preread/body buffer tuning - No telemetry, no database - Drop 512 MB test file; patch script now also substitutes __SERVER_DOMAIN__/__SERVER_IP__ placeholders Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
