Last I checked SHA-256 was faster than SHA-1, and SHA-512 was even faster (though the output is annoyingly long).
How could SHA-512 be faster? It does more rounds of the exact same operations as SHA-256 with a bigger state. Although if it really were faster, SHA-512/256 gives you a truncated version.
