Speed Test
Measure your internet download and upload speeds.

Run a multi-stream download, upload, latency, and jitter benchmark.
- Download: 5 parallel streams of incompressible data over a 7s window; the first 1.2s (TCP slow-start) is excluded so the result reflects steady-state throughput.
- Upload: 3 parallel POSTs of cryptographically-random bytes, measured the same way.
- Ping & jitter: 8 tiny round-trips — latency is the minimum (unloaded) RTT; jitter is the mean variation between samples.
- All traffic is measured against this app's own server, not a dedicated speed-test backbone — results reflect the real path between your browser and tcpx.
