Is there a performance impact for using TDE?

Interview Questions

1. Is there a performance impact for using TDE?

Yes, some performance overhead is involved in using TDE. The encryption and decryption process do require additional CPU cycles. The overhead for using TDE ranges from about 3 percent to 30 percent, depending on the type of workload.

SQL Server instances with low I/O and low CPU usage will have the least performance impact. Servers with high CPU usage will have the most performance impact.
