I am very confused about Sessions and connectios and so on.
If I just refresh the login page, a Session appears even if I am not logged in.
> you need a session before you login otherwise server side code has no way to store your login and pw to compare with valid choices
I logged in and Sessions stay in 1, Sessions data increments.
> correct
I logged out and sessions goes to 0
> correct as the session can be deleted on a logout
an then goes to one again.
> not sure about that unless you logged out back to your login screen
And connections confused me too.
> the greater number of concurrent connections uses more resources. The connections will be running 1 or more threads. Looking at the number of sessions, connections and Threads will help you assess the potential capacity of your server resources.
I´ve done a small video with this, see it its more understandable than my words.

PD: How can I add a List to the perfomance page to see which IPs/user are logged in now?
