These end-to-end test scenarios drive a number of MQTT clients sending measurements into the platform. The clients are connecting to the [MQTT service](https://cumulocity.com/docs/2026/device-integration/mqtt-service) and sending measurements using the [JSON via MQTT protocol](https://cumulocity.com/docs/2026/smartrest/json-via-mqtt/). The measurements are sent in PERSISTENT [processing mode](https://cumulocity.com/api/core/#section/REST-implementation/HTTP-usage) and stored in the operational store. All measurements are received and processed by Streaming Analytics at the rate they are sent into the platform.

The **Narrow** scenario features a small number of MQTT clients, each of them sending an equal and high rate of measurements per second into the platform, recording the aggregate throughput across all clients. The **Wide** scenario features a very large number of devices each of them sending 1 measurement per second into the platform. The maximum achievable result is the best result that could be achieved without Edge running out of CPU and RAM.

| Scenario                                       | CPU threads | RAM  | Maximum achievable result |
|------------------------------------------------|-------------|------|-----------------------------|
| **Narrow** - 10 clients connected              | 8           | 16GB | 25000 measurement/s |
|                                                | 16          | 32GB | 47500 measurement/s |
| **Wide** - Each client sending 1 measurement/s | 8           | 16GB | 1200 connected clients |
|                                                | 16          | 32GB | 2200 connected clients |
