    if you have performance issues just with a very simple config
    sending a stateless sip reply, then check your system/firewall
    configuration/limits. Specially on centos, I have seen a lot of
    restrictive traffic rates limits set by selinux. Also, if you run in
    a virtual machine, there can be limits enforced by the vm platform.<br>
    <br>
    If you still cannot sort out, I would just run similar tests on a
    vanilla debian.<br>
    <br>
