The feature won't affect performance if the Snapshot feature is not in use. When snapshots are used, the performance can get impacted proportionate to the number of snapshots that are actively read from and the number of concurrent snapdiff operations,

There should be no security implications when snapshot feature is not in use. Snapshots can be taken only by the owner of the bucket. Total number of snapshots in the system is limited by Ozone conf.
