Response time significantly much higher in lastest version of MFCUK?

[axiomatico]

Here the time experiment with same commands on mfcuk and mfoc and the same tag&reader but diferent versions of nfc-tools.

Results (min aprox):

MFCUK 0.3.3, libnfc 1.5.1 & mfoc 0.10.3 > Time to obtain all keys: 15 min (2min mfcuk and 10min mfoc with only one probe by sector)

MFCUK 0.3.8, libnfc 1.7,1 & mfoc 0.10.7 > Time to obtain all keys: 60 min (15min mfcuk and 45min mfoc with 20-45 probes by sector)

In two case i use these commands: "mfcuk -C -R 0:A -v 2" and "mfoc -k xxxxxxxxxxx -O keys.mfd -P 100"
Tag&reader: Mifare classic 1k tag, reader SCL3711.

Why the lastest version of nfc-tools are more slow?

Well, this is interesting. I'm having problems with mfcuk... The Nt not going up passed 1 or Nt going Up together with the auths, never finishing and getting error 9 at some point.

Any pro or dev who Can help?
