What version of Slurm are you using?
The job_submit plugin was moved in version 15.08 to reduce or eliminate this problem.
Quoting Ulf Markwardt <[email protected]>:
Dear List, it seems that even a small lua script in the job submit plugin drastically decreases the performance of slurmctld in a high throughput system, so that Slurm becomes unresponsive. Can somebody here confirm such an observation?
