We were able to create testing scenarios, however we have some problems during initial logins from some computers used for test. Is it possible to delay login procedure not to cause “ļogin storm” from testing computer?

The reason for the “ļogin storm” is because you probably use the steady load pattern where all virtual users are instantiated simultaneously https://support.stresstimulus.com/display/doc52/Steady+Load
To avoid the login bottlenecks, you can instantiate virtual users sequentially. To do that, use the step load pattern https://support.stresstimulus.com/display/doc52/Step+Load
For example, you can use the following settings:
Start VU 1
Sep VU increase 1
step duration (s) 20 20
Max VU N

This way, the login transaction for VUs will space out by 20 seconds.
