I'm really not an expert, but IIUC you're just wasting a lot of CPUs for a process that shouldn't use so many. Pinning it to one CPU could improve performance if the user jobs you're running are actually saturating the machine and are massively interconnected (every task needs the results of all the others to proceed), so that having a task that temporarily suspends the user job to do other things could have a cascade effect on the other tasks. But under normal workload you shouldn't see any difference.
