Christoph Berg performs some tests:
It’s been a while since the last performance check of Transparent Data Encryption (TDE) in Cybertec’s PGEE distribution – that was in 2016. Of course, the question is still interesting, so I did some benchmarks.
Since the difference is really small between running without any extras, with data checksums turned on, and with both encryption and checksums turned on, we need to pick a configuration that will stress-test these features the most.
Read on to see the test setup and how things perform. I’m a bit surprised that there’s so little throughput difference here.
