--format=crypt is a good tip.

Team Hashcat said: "... recent breaches. Statistically the average
password length is eight (8) characters."

It is possible to have optimized formats without limits. Though I

Though it is possible to look into reverse way: to add formats with
lesser maximum length to achieve higher speeds. Though it seems
disputable.
Thanks!
