Self-hosted multi-stream throughput & dual-line aggregation probe — client ↔ Cloudflare edge.
Per-stream throughput (live)
Idle. Pick streams + duration, then Start.

How to read this. A single stream caps at one WAN line (~300 Mbit); the
aggregate across many parallel streams is what reveals dual-line balancing — if both
300-Mbit lines are being used, the aggregate can climb above a single line's ceiling.
This test measures client ↔ Cloudflare edge, not raw line capacity. On the
RU-direct path Cloudflare is traffic-shaped, so a low number here may be the shaper, not your lines —
run the test through your VPN exit (check the colo/IP above shows Poland/Turkey, not RU) for a clean read.
For true per-line aggregation, correlate these numbers with the router's per-interface counters
(eth3 and eth2.4): if both lines' RX/TX climb together during the download, aggregation is real.
