MÓDULO PW.Art

Playwright agents — browser-realistic HTTP/2 + HTTP/3 load.

Function

Headless-Chromium-driven workload generator. Each agent navigates real pages via Playwright (full DOM + JS + subresource fetches), captures protocol negotiation + byte counts + Web Vitals.

Differentiator vs K6.Art: PW measures what your customers actually see in their browsers. K6 measures wire-level throughput (datasheet number). PW captures the inflation gap.

• playwright_tcp_sockets_open — connection pool depth
• playwright_mbps_avg — per-cycle throughput
• playwright_web_vitals_lcp_ms — Largest Contentful Paint (Web Vitals)
• playwright_protocol_negotiated{http2, http3} — which protocol won

Notes

PW + K6 side-by-side is the unique differentiator vs Spirent / Ixia / Keysight. "Inflation Gap %" hero metric per project_pw_vs_k6_strategic_differentiation_2026_05_10.
