Hi Everyone,

Is it possible to speed test RDRAND and RDSEED generators? If so, then
how do we do it?

$ openssl speed -engine rdrand
engine "rdrand" set.
Doing md4 for 3s on 16 size blocks: 8339773 md4's in 3.00s
Doing md4 for 3s on 64 size blocks: 6616610 md4's in 3.00s
Doing md4 for 3s on 256 size blocks: 4132167 md4's in 3.00s
