Gatling load test for 6k users

Problem : I want to confirm, my application will not break when 6000 thousand users are hitting the application concurrently.

How can i achieve this with Gatling?

I have only one user credentials.

I need result and explanation.can anyone help me out of this please.


You'd probably need 6000 user credentials to adequately load test your authentication layer.

Each user will be a single TCP connection. so you'll probably need to do some Linux kernel tuning if you are running from one machine.

And keep an eye on your available bandwidth if running from EC2. I think I'll be moving to GCE as they offer 2 gigabits per second per core.
