How performance testing works in postman?

I’m running performance testing in once of collection.
i want to know how the performance testing works in Postman.

I’ve seen that virtual users send fewer requests if any of my requests take a long time to send a response in API.

so one virtual user waits till the response to the request?

I have a scenario where I want to test 400 requests/minute.

During our performance testing, we observed that some of the API requests are taking longer than expected, leading to a decrease in the number of requests per minute. This has raised concerns about the overall performance of the API under the specified load.

Virtual users are simulated in parallel, but since performance testing runs locally, you can run into memory or other issues. Here’s more information about how it works.
