Hi Billy,
Thank you for your reply.
1. Huge pages are properly set
Hi,
I don't see any errors relating to the dpdk interfaces. But it is also not
clear where the user-space drivers are bound and the hugepage memory is set up.
So double check those two items.
Is the dpdk-p0 interface being attached to br-flat? Even if there are issues
with the dpdk port the br

Hi Tcnieh,
Looks like your nics are on NUMA1 (second numa node) – as their pci bus number
is > 80.
But you have not told OvS to allocate hugepage memory on the second numa node –
the 0 in “--socket-mem 1024,0).”
So you need to change your line to something like:
ovs-vsctl --no-wait set Open_vS
Hi Sara,
This article
https://software.intel.com/en-us/articles/ovs-dpdk-datapath-classifier gives
practical overview of how megaflows, aka wildcarded or datapath flows, work at
least in the ovs-dpdk (userspace datapath) context.

Billy

Hi,
One thing to look out for with DPDK < 18.05 is that you need to used 1GB huge
pages (and no more than eight of them) to use virtio. I’m not sure if that is
the issue you have as I think it I don’t remember it causing a seg fault. But
is certainly worth checking.
If that does not work pleas
Are you setting emc-insert-inv-prob in the ovsdb before OvS starts?
There should not be any packets being processed before the configuration is
applied but if you remove the early startup time until you are sure the system
is in a steady state from the analysis do you still see time being spend
Hi Krish,
You will need to compile with debug info and also with in-lining turned off.
Many functions get in-lined and in that case the perf report cannot attribute
time to the in-lined function but only to the caller. Obviously performance
overall drops in that case but the relative cost of ea

Hi Wang,
Typically I reserve between 512M and 1G on each Numa.
There is no formula I am aware of for how much memory is actually required.
Fundamentally this will be determined by the maximum number and size of packets
in-flight at any given time. Which is determined by the ingress packet rate,
results were potentially
affected by this issue.

/Billy.

If you create several PMDs on the NUMA of the physical port does that have the

Hi All,
Just to add something to this conversation that has not been explicitly
mentioned below.
Brad outlines how to set other_config:dpdk-socket-mem to reserve hugepages from
both NUMA nodes in order to be sure to avoid pci topology issues.
Strictly this doesn’t have to be done on both nodes
Hi,
I have been performing tests investigating latency profiles of low-bandwidth
time-sensitive traffic when the system is busy with 'normal' traffic.
Unsurprisingly the latency-sensitive traffic is affected by the normal traffic
and has basically the same latency profile as the normal traffic.
