But in my POV if you have a workload with 30 or more users running several applications, if the suspended processes can have a lower scheduling the CPU will have less wait states, but maybe you are right. :D
Powertop can help in this question ;)
Yes, I'd like to see empirical measurements - preferably with a sensitive watt meter :)
I'm only guessing here, but while it is probably true, that a process with a lower priority will not decrease the power consumption of the server it is running on, you should see an increase in responsiveness for currently active tasks, like X2Go sessions in an active/connected state. Which would allow you to stack more users onto a single server, rather than having to buy a second one. And that's quite an energy consumption there, both in electricity during its lifetime and in electricity/resources needed to build the server. Of course, this is assuming that a certain percentage of your users is always idle/suspended/disconnected or not logged in at all.
