in the same direction as previous answers: did you consider the user.slice feature in systemd? This would let you use cgroups to constrain a users complete login sessions. No extra software needed. See https://www.freedesktop.org/software/systemd/man/systemd.resource-control.html especially "CPUQuota". These limits can be set in a user.slice. Best Regards Christof -- Dr. rer. nat.
