It has 4 cores but the openssl benchmark is single threaded. Here are
the repeated benchmarks with the openssl process pinned to a single
core on the Intel(R) Core(TM) i5-2500 CPU:
$ sudo taskset -c 0 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 582968.81k 677468.97k 700901.55k 714349.57k 714599.08k
712927.91k
$ sudo taskset -c 0 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 274685.32k 966377.81k 2179320.66k 3372390.40k 4011008.00k
4068474.88k
Another thing proving I didn't screw up the test result is that
Intel(R) Xeon(R) W-2155 CPU has 10 physical cores and the difference
is not 10 times.
