# Scaling Issue

### Description

Scaling issues are performance problems that emerge when the code is run concurrently. Digma analyzes the correlation between concurrency and performance and can detect when the degradation becomes problematic. To see a detailed analysis click on the `Histogram button`

### Thresholds

Found bad scaling in analyzing the concurrency graph. Requires four levels of concurrency to be measured at four different time intervals (different seconds).

## 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.digma.ai/digma-developer-guide/digma-features/insights/scaling-issue.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.
