As mentioned in the main blog posting „Performance Test for Percona Transparent Data Encryption (TDE)“, here’s a detailed explanation for the TDE performance test.

Hardware Details

This test was run on a dedicated physical server, to avoid external influences and fluctuations from virtualization.

The server has a Intel(R) Xeon(R) Gold 5412U CPU with 48 cores, 256 GB RAM, and a 2 TB SAMSUNG MZQL21T9HCJR NVram disk dedicated for the tests (OS was running on a different disk).

This blog posting compares the performance of the pg_tde by Percona extension for PostgreSQL with the performance of an unmodified PostgreSQL. The pg_tde by Percona extension provides encryption for both data pages on disk as well as WAL files on disk - Encryption at Rest. The extension is currently in the rc stage (release candidate). This test does not compare pg_tde by Percona to other products. It tests the extension performance and compares with unmodified PostgreSQL, and shows how much overhead it is to encrypt data at rest, and encrypt WAL.
