Comment 2 for bug 1814456

Good question! The answer is as follows.

    $ su
    Password:
    # time ufw disable
    Firewall stopped and disabled on system startup

    real 0m0.311s
    user 0m0.235s
    sys 0m0.074s
    # time ufw enable
    Firewall is active and enabled on system startup

    real 0m0.520s
    user 0m0.369s
    sys 0m0.167s

So it seems that ufw performs the operations some thirty times faster than gufw.
