Linux processes can have different CPU and IO priority (nice and ionice).
Why is there a need to have different CPU and IO priority?
Is there any real world usage for having them different?
What real world use cases have you found that need different CPU and IO priority? Like higher than normal CPU priority but lower than normal IO priority or viceversa.
I want to run a process without network access but at a later time give access to the network.
The computer will have full network connection as all the other processes but I want to start just one process without network access. (I have already checked this process runs fine without networking)
I would like the users of the system to be able to setup processes that run at system startup that they can setup by themselves. How may I do it?
I would like to know how databases (like MySQL) are able to manage per user resources (like Oracle Database Resource Manager does) to be able to have users that may only get resources only when the database is mostly idle.
