The goal was to see impact on perf with and without encryption.
I made some test with sysbench and server crashed few time after (and server was inactif), because I could finish my test and I see that the encryption decrease perf of 15%.
last sysbench :
sysbench --test=/usr/share/doc/sysbench/tests/db/oltp.lua --num-threads=32 --mysql-host=localhost --mysql-user=root --db-driver=mysql --mysql-password=password --mysql-db=test --max-time=60 --max-requests=0 run
(with table encrypted)
Ubuntu 12.04 + MariaDB 10.1.6 (from the repository)
