Etherpad Load Test

Clients for load testing an Etherpad instance, including legacy and sweep modes. Version 2.0.3, actively maintained by the Ether team. Supports configurable lurker and author counts, duration limits, and a sweep mode for reproducible concurrency curves with Prometheus metric scraping. Key differentiators: designed specifically for Etherpad's real-time collaboration model; built-in test for multiple pads in parallel; produces report artifacts (JSON, CSV, Markdown) suitable for plotting and issue reporting. Requires Node.js >=18.0.0 and ep_etherpad-lite >=1.8.6 with load-testing enabled.
