SpeedTester.pk uses the same HTTP parallel-stream methodology as Speedtest.net — 8 simultaneous download connections and 6 upload connections to the nearest Cloudflare edge server in Pakistan. A sliding measurement window captures peak sustained throughput, giving results comparable to what you see on Speedtest.net. The test runs a three-phase sequence: Ping → Download → Upload.
