Hi Team,

We are new to gatling and framework, we are trying to test a server using the simulation.

Question we have is on below line. What is implied if the myramp is 0 and users are 100?. Does that say we are injecting 100 users at once? since myramp is 0?

“scenario.inject(rampUsers(users) over myRamp”

I understand we have one more like “atOnceUsers(10)” . But want to check if our above understanding is correct?

Any help is appreciated. I tried to find this information online, but couldn’t found it anywhere.

Thanks  
Ratnakar
