Description Doug Meyer 2019-03-14 15:43:24 MDT 
Education regarding Bug 2198
The man page states increasing the max_script_size "Larger values may adversely impact system performance."  Anticipating my fine users, why is that?  

Thank you,
Doug Meyer
Comment 1 Marshall Garey 2019-03-14 16:11:15 MDT 
Upon batch job submission, the job script is sent from the login node to the slurmctld across the network, then saved to the StateSaveLocation. When the batch job starts, the batch script has to be read from the StateSaveLocation and sent across the network to the batch host compute node. As you can imagine, very large batch scripts and slow filesystem and/or network i/o could be a bad combination.

Does that answer your question?
