faster with --markov-disable

[forumhero]

playing around with the markov feature in Lite and noticed that it's faster if markov is disabled when trying to crack the example hash of "hashcat!"

markov-disable takes 15 secs to crack.
markov with default hcstat or rockyou.hcstat takes about 3mins.

is this normal?

command is:
oclhashcat-lite64.exe --pw-min 8 md5hash -2 ?l?s ?l?l?l?l?l?l?l?2
