Stress Testing by increasing conncurrent requests

I am new to Gatling and was exploring the various features available. I would like to know the feasibility of stress testing with Gatling.

Injecting one user with 50 requests per second and this has to run for 10 seconds and this step has to repeat for users

Can you help us how to inject the scenario?

Maybe this is what you are looking for

Keep in mind that Throttle should not be used with multiple APIs scenario because it won’t do an equal distribution between them.

Injecting one user with 50 requests per second and this has to run for 10 seconds and this step has to repeat for users

You would use a loop and pace to make sure that your user doesn’t make MORE than 50 requests per second.

But as user flows are sequential, it means that your application must be able to respond in less than 20 ms, which could be very optimistic.

Generated scala by using HAR converter. Now my Scala file has n number requests from Login to last activity.
Generally in gatling when you inject the number of users. (Ex: Users:5). Will other request execute successfully when the login attempt was fail?
