Speed depend on count of hashes inside the hash file and/or nonce-error-correction value.

Thanks for the attention. Further testing shows that the performance decrease only happens with one of my .hccapx files and certain cracking method (4800000x words and 1000x rules), and the decrease disappears when --nonce-error-correction=0 is set.
