Ramp-Up Period (seconds): The time it takes for all threads to reach the full number (usually 1 second).

Loop Count: The number of times each thread will execute the test (usually 1 for a login test).

3. Add an HTTP Request Sampler:

Right-click on the thread group and select "Add" -> "Sampler" -> "HTTP Request."

In the HTTP Request sampler properties, configure the following:

Protocol: HTTP (assuming port 80) or HTTPS if using SSL.

Server Name or IP: localhost (or the actual IP address of your server if not local).

Port Number: 8000

Method: POST
