    you can start from 1-CPU license, and switch between 1/2/4/8 license later at any time. please refer wiki page for more explanation:

    enable sync cookies to defend syn flood attack effectively: (in example of linux)
    echo 1 > /proc/sys/net/ipv4/tcp_syncookies

    this is at OS level. the goal of the attack is NOT to establish valid tcp connections.

    however litespeed's anti-dos feature is for attacks with ESTABLISHED tcp connections, so not for syn flood attack.
