Gatling hardware configuration

Hello

What are the minimum physical characteristics (memory, network card, CPU, disk, etc. …), with the number of transactions / second maximum used with Gatling?
At what point do I add another injector?
Thank you

It really depends on your needs. We don’t have any metrics, so it’s a matter of trial and error. Do you saturate the NIC? Is your CPU at full throttle? Is your memory full? etc
