Info: The described step can only be performed on the on-premise version of Assets Server, not on the cloud version.
Because Spotlight is probably not used on the system on which Assets Server is installed, you can improve performance by disabling it.
Alternatively, at least exclude your Elvis Hot Data and Elvis Data folders from being indexed by Spotlight.
The primary method on MacOS is using launchctl, (this requires an administrative password):
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
