Alternatively, to mitigate the impact of :dbcommand:`cleanupOrphaned`,
you may prefer to run the command at off peak hours.

It is also possible to tune the performance impact of :dbcommand:`cleanupOrphaned`
with two server parameters :parameter:`rangeDeleterBatchSize`
and :parameter:`rangeDeleterBatchDelayMS`

To limit the number of documents deleted per batch, you can set
`rangeDeleterBatchSize` to a small value such as `32`.

To add an additional delay between batch deletions, you can set
`rangeDeleterBatchDelayMS` above the current default of `20` milliseconds.

Note that these affect all range deletion including normal
:doc:`chunk migration</core/sharding-balancer-administration/#chunk-migration-procedure>`.
