+## Performance Test Harness
+
+## Submitters
+- Cherry Wang (IOTech)
+
+## Changelog
+[approved](https://github.com/edgexfoundry/edgex-docs/pull/1318) (2024-01-29)
+
+## Market Segments
+- All
+
+## Motivation
+The EdgeX Performance Test aims to evaluate the efficiency of the EdgeX services in handling a large volume of data transmission from the south side to the north side in a manufacturing context. This use case is motivated by the need to understand how EdgeX performs under heavy data loads and to identify potential areas for optimization.
+
+By providing the Performance Test Harness, users can execute the Performance Tests with their own hardware and devices environment to evaluate the capability of the system.
+
+## Target Users
+- System Developer
+- System Integrator
+
+## Description
+The EdgeX Performance Test involves the south side generating a substantial amount of data and transmitting it through EdgeX services to the north side. This process aims to simulate real-world scenarios where data flow between manufacturing devices and backend systems is intensive. The observation of this data transmission allows for an in-depth analysis of EdgeX's resource utilization patterns.
+
+## Existing solutions
+- The basic performance metrics collection in TAF: https://github.com/edgexfoundry/edgex-taf/blob/v3.1.0/docs/run-performance-metrics-collection-on-local.md
+- Users may prepare the customized performance test script to measure different metrics according to their own requirements
+
+## Requirements
+- A device / app-service profile template shall be defined that allows user to specify the device and app-services to be involved.
+- A configuration shall be defined that allows user to specify the number of device and app-services, server address, and etc. to run. e.g. 10 devices per profile and 10 app-services.
+- Tools for monitoring real-time resource utilization during transmission. e.g. Telegraf, InfluxDB. The following resources will be monitored:
+    - Host metrics.
+    - Services metrics. e.g. app-service, device-services, core-services
+- A tool to schedule a one-time task at a specific time for generating report. e.g. `atd (at daemon)` service
+- A script to use for retrieving metrics and generating report.
+- The capability to integrate additional services in the performance tests, such as eKuiper.
