May I know that while enabling data volume encryption, What is the performance impact?
Please i need your experts views on the above query, it is urgent.
Thanks in advance.
Data volume encryption only incurs an overhead when data is decrypted during read from disk and encrypted when writing to disk. Data in memory is always decrypted and therefore there is no performance penalty associated with access to in-memory data.
Scenarios that involve access to data volumes and therefore have a performance impact are:
Column loads Savepoints and database snapshotsData backupsHybrid LOBs
These scenarios are dominated by I/O and the encryption related CPU overhead is minor. Usually the overall performance impact isn't higher than a medium single-digit percentage.
