Subject: [External] Re: Database Encryption
We are using TDE for encryption and also getting the wait event "CPU+wait for CPU" ... As an evidence we decrypt the database and it behaviour back to normal as it was prior to encryption.

Can you prove that there has not been a change in execution plans?

All,
We have encrypted almost all the datafiles of the database, post that the performance of the database degraded to almost 40-50%
Could anyone suggest what is the other alternative method that we can use in order to secure data with bit performance impact.

Arun
