OK. After running some benchmarks of CBC and XTS mode it turns out XTS is about 4 times faster on the following hardware: Intel(R) Core(TM) i5-2500 CPU and Debian 9: $ openssl speed -elapsed -evp aes-128-cbc The 'numbers' are in 1000s of bytes per second processed. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-cbc 584819.37k 677239.36k 703971.41k 711211.69k 714863.96k 714817.54k $ openssl speed -elapsed -evp aes-128-xts The 'numbers' are in 1000s of bytes per second processed. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-xts 274325.95k 966530.77k 2188390.83k 3392874.50k 4025499.65k 4070801.41k Intel(R) Xeon(R) W-2155 CPU and Debian 9: $ openssl speed -elapsed -evp aes-128-cbc The 'numbers' are in 1000s of bytes per second processed. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-cbc 906050.14k 1525035.99k 1568800.68k 1583081.13k 1571853.65k 1572377.94k $ openssl speed -elapsed -evp aes-128-xts The 'numbers' are in 1000s of bytes per second processed. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-128-xts 583329.93k 2032246.29k 4287464.87k 5861887.66k 6374801.41k 6582566.91k ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
