is it necessary to log out
I am running a job on a Linux stand alone machine, which takes about 2 weeks to complete. I haven't logged out of my user account for about a week. I am planning to start another job which might take an additional 2 weeks. I was wondering if it is necessary to log out of my user account to refresh the system? Will the system performace be affected if I stay logged in for a long time? I appreiciate your help in advance.
