OK James,
Thanks for sharing your own experience.
What I would need right now is to know from maintainers if this latency
behaviour is something inherent in DPDK in the particular case we are
talking about. Furthermore, I would also appreciate it if some maintainer
could tell us if there is some w
No. I didn't notice the RTT bouncing symptoms.
In high throughput scenario, if multiple pipelines runs in a single cpu
core, it does increase the latency.

Dear James,
I have done two different tests with the following configuration:
[PIPELINE 0 MASTER core =0]
[PIPELINE 1 core=1] --- SWQ1--->[PIPELINE 2 core=1] -SWQ2>
[PIPELINE 3 core=1]
The first test (sending a single ping to cross all the pipelines to measure
RTT) has been done by settin
No. We didn't see noticable throughput difference in our test.

Thanks James for your quick answer.
I guess that this configuration modification implies that the packets must
be written one by one in the sw ring. Did you notice loose of performance
(in throughput) in your aplicación because of that?

Yes, I experienced similar issue in my application. In a short answer, set
the swqs write burst value to 1 may reduce the latency significantly. The
default write burst value is 32.

Hi all,
I am developing my own DPDK application basing it in the dpdk-stable
ip_pipeline example.
At this moment I am using the 17.11 LTS version of DPDK and I amb observing
some extrange behaviour. Maybe it is an old issue that can be solved
quickly so I would appreciate it if some expert can sha
