Messing with JavaScript and the DOM
summary
Measures latency by loading a 1×1 GIF (35 bytes) and differentiating TCP handshake time using a second request on the keep‑alive connection; measures throughput by progressively larger images (tested up to 600 MB) with per‑request timeouts ~800–1200 ms and reports 25–30% throughput error versus 5–1% latency error; DNS timing uses random subdomains/wildcard lookups; IPv6 checks use direct IPv6 addresses and AAAA lookups; code and plugins live in Boomerang and network‑scan examples point to sammy.pl/mapxss.
