[SR-Users] rtpengine cpu usage

[Diego Nadares]

Thanks for your replies.


>System CPU or User CPU?
Well, it's cpu from top.
%Cpu0  :  8.3 us,  6.2 sy,  0.0 ni, 84.4 id,  0.0 wa,  0.0 hi,  1.0 si,
 0.0 st
%Cpu1  :  6.2 us,  5.2 sy,  0.0 ni, 86.5 id,  0.0 wa,  0.0 hi,  2.1 si,
 0.0 st
PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND

Yes, rtpproxy uses less than rtpengine. Right now, with 300 calls, rtpproxy
is using 7% and rtpengine almost 13% of cpu.

I compiled just daemon mode with no kernel module. I think I will try this
too, eventually. I have to see how to compile it here.

This is my cfg. Could you check if this is ok?

route[NATMANAGE] {
        xlog("L_ERR", "NATMANAGE $Ri $rd  $du $avp(rtpengine)");

        #Just replies
        if (!is_pure_ip($rd)){
                if ( $avp(rtpengine) == "1"){
                        xlog("L_ERR", "NATMANAGE $rd Not a valid ip -
rtpengine active");
                        rtpengine_manage("replace-origin
replace-session-connection ICE=remove");
                }
                exit;
        }

        if (is_ip_rfc1918($Ri)){
                if (is_ip_rfc1918($rd)){
                        xlog("L_ERR", "NATMANAGE Priv -> Priv");
                        #Not proxying for now
                        $avp(rtpengine) = "1";
                        rtpengine_manage("direction=priv direction=priv
replace-origin replace-session-connection RTP/AVP");
                }
                else{
                        xlog("L_ERR", "NATMANAGE Priv -> Pub");
                        $avp(rtpengine) = "1";
                        #rtpengine_manage("direction=priv direction=pub

                        rtpengine_manage("direction=priv direction=pub

                }
        }
        else{
                if (is_ip_rfc1918($rd)){
                        xlog("L_ERR", "NATMANAGE Pub -> Priv");
                        $avp(rtpengine) = "1";
                        #rtpengine_manage("direction=pub direction=priv
replace-origin replace-session-connection RTP/AVP ICE=remove");
                        rtpengine_manage("direction=pub direction=priv
replace-origin replace-session-connection ICE=remove");
                }
                else{
                        xlog("L_ERR", "NATMANAGE Pub -> Pub");
                        $avp(rtpengine) = "1";
                        #rtpengine_manage("direction=pub direction=pub

                        rtpengine_manage("direction=pub direction=pub
replace-origin replace-session-connection ICE=remove");
                }

        }

        return;
}

Thanks!

Diego.
