Latency is not reported as raw time-to-first-byte. The edge endpoint's own
processing time is subtracted using the `Server-Timing` response header, and
where the edge exposes kernel TCP statistics that round-trip is reported
directly — it tracks ICMP to within about a millisecond. Throughput is bytes
divided by elapsed time over a steady-state window that excludes TCP slow
start; no percentile of the peak is ever substituted for the mean, so every
figure reconciles with the byte counter shown beside it.

## Tools

- [Speed and bufferbloat test](/tr/hiz-testi): Download, upload, ping, jitter, and latency measured again under load to grade bufferbloat from A+ to D.
- [Gaming ping radar](/tr/oyun-ping-radari): Live round-trip measurement to region-pinned endpoints near the major competitive game regions.
- [WebRTC and DNS leak detector](/tr/dns-webrtc-sizinti-testi): Checks whether the browser exposes a local address via WebRTC and whether DNS-over-HTTPS is reachable.
- [Download time calculator](/tr/indirme-suresi-hesaplayici): Converts a file size and a line speed into a transfer duration.
- [Guide and FAQ](/tr/rehber-ve-sss): What bufferbloat is, how to get an accurate reading, and how Mbps relates to MB/s.
