Nearly everything of size is in sys/conf/GENERIC.

Be careful there, though. There are many dependencies that config
cannot catch for you, and no configurations outside of GENERIC are,
strictly speaking, supported.

You're looking to reduce the number of rounds used in your blowfish
password hashes. You need to change the password after altering
this value so the new hash reflects the changes. Each additional
round doubles the processing time required to compute the hash.
