Last updated on OCTOBER 04, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.1 and later
Advanced Networking Option - Version 12.1.0.1 and later
Information in this document applies to any platform.

Goal

After upgrading to 12.1.0.1.0, you observe a performance degredation on TDE functions (compared to 11.2.0.4)

Using a tablespace without Encryption:

with 11.2.0.4
SQL> @execute_insert
INSERT AP No.0 finished!

PL/SQL procedure successfully completed.

Elapsed: 00:02:58.63

with 12.1.0.1.0
SQL> @execute_insert.sql
INSERT AP No.0 finished!

PL/SQL procedure successfully completed.

Elapsed: 00:07:03.87


So 12.1.0.1.0 takes 4 minutes more than 11.2.0.4
