Hello,
This is standard AES implementation based on FIPS 197 ("standard" means
also "slow").
OpenSSL daes not have such implementation, OpenSSL have optimized AES
implementation based on function AES_encrypt() which far more faster then
standard implementation. Standard implementation is good for learning but
not in real life.
Best regards,
