    Firewalls are good specially if u have many competitors sometimes ppl do things like ddos and stuff.. it doesnt affect the load a lot so its better to keep it

    Firewall will not affect your load that much one way or the other. I would really be looking through all of my log files and watching top to see what is eating up resources. Poor programming skills and other things could be hurting you as well. Also, I have found that most often you are either getting nailed by spiders or spammers.

    If you want to find out if it is spammers and you use the PHP Mail() function then you can try the following:
