Hi Matthew,
When capturing at high speeds you should avoid switching desktop or
even better using a desktop at all since it may interfere with the
capture process.
If you still wish to run the desktop, you can try to isolate the
capture cores by the means of isolcpu .
If you have further questions, please contact my collegue Alfredo in CC.
Regards,
Emanuele

Hi,
I'm evaluating PFRING ZC on an Intel X710, aiming for 100% capture up
to 10G.
Capture appears reliable if I leave the system alone while capturing,
but if I switch desktops or reload a webpage or thrash alt-tab, for
example, I see packet loss. It becomes stable again when I leave it
alone. Server has plenty of cores, rx queue len set to max at 4096.
Also, if using 2 or 4 RSS queues for example, dropped packets are
always reported on @0, even if actually dropped from other queues.
Is there much that can be done to improve this? I've read that an
X520 has a larger buffer - would this help?
Regards,
Matt.
