summary

FastBTS implements fuzzy rejection sampling with a real-time crucial interval detector and elastic bandwidth probing, plus data-driven server selection and adaptive multi-homing. With only 30 servers it matches Speedtest.net’s accuracy (12,000 servers) while making tests 5.6× faster and 10.7× more data-efficient; evaluations show 5–72% higher accuracy, 2.3–8.5× shorter duration, and 3.7–14.2× less data. Example runs: 3.1 s/37 MB vs 15 s/176 MB (Wi‑Fi) and 4.1 s/168 MB vs 15 s/≈1 GB (5G).
