At my university, there was a clock in the window of the computer center that indicated the turn-around time which was how long a submitted job would take to be processed. During the quarter, it would vary from 5 minutes to an hour. At the end of the term, when everyone submitted their final projects, it would quickly increase from an hour to, sometimes, more than 24 hours. Imagine having to submit your projects on Friday while getting one and only one run each day leading up to it. It was quite stressful.
