The macOS process that maintains the Spotlight index, mdworker, is aggressive in building its database. Mdworker will begin creating this database quickly after being enabled. Even a few macOS systems could cause significant storage traffic and degrade performance for other users.
When the OneFS file system is used for latency sensitive workflows, such as video editing, Spotlight search should be disabled on network storage. For fast file system search in those environments, alterative tools may be more appropriate.
You can disable Spotlight indexing of a network volume in several ways.
From the macOS UI, add the network volume to the list at:
System Preferences > Spotlight > Privacy
From the macOS command line, specify:
mdutil -i off /path/to/network/volume
or
mdutil -d /path/to/network/volume
