How to work with LoadRunner?

[emerson]

The task is to conduct load testing of the mail system. 1000 users should connect to the mail at the same time, go through the script (log in, write a letter, etc.). I made a script for a script for one user, everything works, but what about the rest of the users? Create a script for them too? Or is it all possible with one script? How it should be implemented? Maybe I'm doing something wrong?

Create a script for them too?

One is enough for a start. At least for a start.

You are doing everything right. Only in the Controller module you need to set the number of virtual users.
