# Job Summary

This tab provides an overall look at the results and a summary for all iterations. The test results per iteration are shown aggregated across all the clients. This gives an idea of how many clients succeeded per iteration.

The next graph shows the client activity over time. Here, you can see how many individual clients were active at the given points in time.

The final graph shows the average, minimum and maximum time it took to send a message to the back-end. This is a true measure of your server performance, as it doesn't count the time it took to generate the message. As we could see, the packet sending latency is fairly maintained consistent with time. 

{% hint style="info" %}
Packet sending latency is highly dependent upon the protocol and transport. E.g. for MQTT QoS 0, the packet sending latency will be lower, as the transmission of the packet is marked completed almost immediately. If the QoS value used is 1 or 2, the sending latency will be much higher for the same test, as higher QoS values require every sent message to be acknowledged for delivery, therefore considerably increasing the latency.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.iotify.io/getting-started/analyze-the-results/job-summary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
