~300MB/s on one core of 13-years old i5 SHA-256(used in BitTorrent v2). Newer cores can about half a gig per one. Less than 3 days on one core then. Less than day on 3 cores.*

* assuming no additional performance penalty for increased power consumption and memory bandwith usage

My guess storage bandwidth would be biggest bottleneck.

Found relatively old article(in Russian, just search for openssl and look at graph that mentions SHA-512 which is SHA-2 too) that says i7-2500 all-cores throughput is slightly over 1GB/s.
