This is a such a big problem that a conference recently was dedicated to fixing it. Sometime this year there should be a new notebook system designed for dealing with lots of users. There are alternative notebook servers such as http://alpha.sagenb.org, but I don't recommend telling 75 students to use it. The notebook was not designed to be used by many users at once. So I recommend waiting until it gets redesigned for scalability.
