Best way to simulate stream of data at hight rate Azure

Question

Hi everybody, I am new to Azure and IoT.
I have build a local simulator of time series data sent in json,running a time trigger azure function. For now I am sending at each call one json data to a RabbitMQ queue, therefore I cannot get below 1s rate. My question is how can I reach the ms time rate? Is there a better way in Azure to simulate a simple stream of data?
[Notice that I would run all on premises in my pc.]

For now it comes to my mind only to send 1000 json together at each one second call, but I am worrying about time performances.

To be honest, if I'm just playing around I usually end up writing a console application that sends device telemetry in a while loop. If I'm feeling fancy I'll add some delays or logic to it. Bake it into a Docker image and you could run it both locally or in Azure (Container Apps/Container Instance). Otherwise, there are a lot of MQTT device simulators to be found online that can do this for you.

Not what you asked, but if you're going to do IoT on Azure, you might be interested in Azure IoT Hub. It's not a full MQTT broker (but does support MQTT), but has a lot of extra functionality around message routing and device configuration. There is a nice Azure IoT Device Telemetry Simulator too.
