ChronoServer

ChronoServer is a specialized test server designed to measure how long it takes mobile and web clients to make various types of requests to a server performing common request patterns. It helps developers simulate and analyze latency and user experience by deploying the server in different geographic locations and testing with varying request sizes and styles. The server also enables evaluation of CDN performance when placed in front of your infrastructure.

Key Features

• Request Timing Collection — Clients fetch a collection of URLs (GET/POST), execute them while timing each call, and report detailed timing data back to the server.
• Configurable Test Batches — Supports named collections of URLs for clients to run, with defaults for bootstrap testing.
• Flexible Data Endpoints — Provides APIs for static (in-memory) and dynamic (database) data retrieval, with optional caching headers.
• Streaming Support — Includes a SockJS interface for real-time, bidirectional communication and data transfer testing.
• Data Retention Control — Configurable retention period for uploaded test data, defaulting to one day.

Philosophy

ChronoServer is built to provide realistic, configurable latency testing for distributed systems, enabling developers to optimize performance and understand user experience across different network conditions.
