SHA-256 assembly language optimization

I'd like to ask about improving SHA-256 performance:

I see on this page,

Intel gives a reference implementation of SHA-256 for its own processors.

How is OpenSSL's implementation related to that implementation?
Is there much opportunity for improvement?

I assume the person who wrote the current OpenSSL assembly probably
looked into every avenue for improvement of performance, but just in
case, I feel I should ask.  Can it get much faster?
