Hi,<br><br>You mention that you have small traffic - how much memory does Suricata use? how many rules do you load?<br><br>thank you<br><br><div class="gmail_quote">On Fri, Nov 30, 2012 at 3:50 AM, xbadou xbadou <span dir="ltr"><<a href="mailto:xbadou@gmail.com" target="_blank">xbadou@gmail.com</a>></span> wrote:<br>
