Description:

Hello,

I found that results in the table F-17
(https://www.postgresql.org/docs/9.4/static/pgcrypto.html#PGCRYPTO-HASH-SPEED-TABLE)
differs 10 and more times from real results John The Ripper shows in single
CPU-core mode

For example, for crypt-md5 there's 171584 hashes/sec, while on my Intel Core
i5 it's about 15969. So time durations as well as relative durations are
incorrect.
