If I am having many ssh instances running at once on a server to many client computers, then how are processor time and cores set up?
For example, I have a 2 Core box with lubuntu running on it. How do two client ssh sessions use the cores?
Also, can I physically log in to the box while it is serving 2 remote clients?
Can it have 3 sessions running or is that too many? If so, is there a protocol that would return in text that the server is busy and full of sessions like QOTD? How would I implement this?
And please don't refer this to ServerFault because this computer is not a business server, although it is professional :). (see ServerFault's FAQ).
