We have just included some optimized x64 assembler to our Open Source SynCrypto.pas unit so that SHA-256 hashing will perform at best speed.
It is an adaptation from tuned Intel's assembly macros, which makes use of the SSE4 instruction set, if available.

And their blog - in Chinese - is at http://blog.qdac.cc/

So I included QDAC3 in our "25 - JSON performance" sample.
Numbers are talking, now.
