Subject: Re: [vpp-dev] Total Packet Process Time in VPP
I run this, I see time is reset.
Start traffic.
“clear run”.
Wait several seconds.
“show run”.
But I did not understand how to do "Add up clocks/pkt/node for data-plane nodes
to form total clocks/pkt" Could you please explain more clearly where and how
to add it.

Add up clocks/pkt/node for data-plane nodes to form total clocks/pkt. Results
valid only for the prevailing vector rate, CPU type, CPU clock frequency, etc..
Vpp nodes run dramatically more efficiently as the vector size increases, up to
the point where rx ring drops occur.

Subject: [vpp-dev] Total Packet Process Time in VPP
Hi everyone, I'm using VPP with trex. I send and receive packets. Is there any
place on Vpp where I can view the total processing time? I see graph runtime
statistic
but I haven't found anything about the time passed here.
I see like this; İn here "time" is not total processing time.
(show runtime command)
Time 1603.9, 10 sec internal node vector rate 0.00 loops/sec 1367859.23
vector rates in 1.5238e5, out 1.5159e5, drop 0.0000e0, punt 0.0000e0
