It is possible to develop an algorithm which calculates the number of active
sessions you have at any one time, but how is that going to help you? You
are experiencing performance problems, and then, sessions don't matter; only
connections do.

In order to reduce the load on the server, you could add some logic in your
"session creation" code, that would only create a session if the number of
current active sessions is less than N. However, that's not a really good
idea either. You are best off trying to get your box to serve all its
visitors.
