Hi Luca,
Sorry for the delay replying the list. Thanks for your advice.
I tested reducing the template to just the minimal fields, and the
performance was way better.
Right now, I left the template with ~50 fields (instead of ~150), and
leaving zbalance in a dedicated core (not sharing threads w
Hi David
your template is huge. Can you please omit (just for troubleshooting)
"--flow-templ….” and report if you see changes in load?
Thanks Luca

Hi,
And now:
- 1.log = scenario in your point 1, including top, zbalance output, and
nprobe stats.

Hi Alfredo,
Sorry, I forgot to attach the files as you said. I sent them awhile ago,
but it seems the mail size is over the limit and get held for approval. I'm
trying now deleting some info from my first email and pasting one file at a
time.

Hi Alfredo,
Thanks for your recommendations.
I tested using core affinity as you suggested, and the in drops disappeared
in zbalance. The output drops persist, but the absolute drops are less than
before.
Actually I had tested the core affinity, but I didn't have in mind the
physical cores. Now I
Hi David
it seems that you have packet loss both on zbalance and nprobe,
I recommend you to:
1. set the core affinity for both zbalance_ipc and the nprobe instances, trying
to
use a different core for each (at least do not share the zbalance_ipc physical
core
with nprobe instances)
2. did you try
Hi Alfredo,
Thanks for replying.

Hi David
please also provide statistics from zbalance_ipc (output or log file)
and nprobe (you can get live stats from /proc/net/pf_ring/stats/)
Thank you

Hello list,
We're using nProbe to export flows information to kafka. We're listening
from two 10Gb interfaces that we merge with zbalance_ipc, and we split them
into 16 queues to have 16 nprobe instances.
The problem is we are seeing about 40% packet drops reported by
zbalance_ipc, so it looks li
