本文介绍了基于消息传递的异步实时交互系统 (RIS) 的一组指标。分析了并发 RIS 的当前趋势，概述了几种分析工具，并确定了常见指标。一组九个指标以统一且正式的方式呈现。说明了测量和计算这些指标的分析器的实现。描述了仪器和可视化工具的实现。案例研究展示了这种方法如何在实际系统的延迟优化过程中证明是有益的。
This article describes a set of metrics for a message-passing-based asynchronous Realtime Interactive System (RIS). Current trends in concurrent RISs are analyzed, several profiling tools are outlined, and common metrics are identified. A set of nine metrics is presented in a unified and formalized way. The implementation of a profiler that measures and calculates these metrics is illustrated. The implementation of an instrumentation and a visualization tool are described. A case study shows how this approach proved beneficial during the optimization of latency of an actual system.
