Subject: Fw: Not able to achieve consistent 10Gbps on Napatech 2x40G card for more than 10 seconds

Hi,

We are evaluating disk2n on Napatech 2x40G card to achieve sending traffic more than 10G.

We started for 10G traffic with 9 pcaps of around 1.5G to send on Napatech port 0.

Initially for few seconds we were able to observe 10G traffic then afterwards it gradually reduces to 2.6Gbps and remains around 2-2.6Gbps for rest of the period.

So, we were not able to achieve consistent 10G traffic with disk2n on Napatech card.

We have also purchased the license for n2disk.

Question. How can we achieve 10Gbps traffic on 2x40Napatech card with driver ntanl_package_3gd-11.6.0-linux?

We tried without caching option also (-b) and the max throughput was 2.5G

# disk2n -i nt:0 -m /tmp/playpcap.txt -c 1 -w 2 -S 3   -C 1024 -I 450  -v

While browsing the link https://www.ntop.org/guides/pf_ring/modules/napatech.html

in section

8.4. Napatech and Packet Copy
If you use the PF_RING (non-ZC) API packets are read in zero-copy. Instead if you use PF_RING ZC API, a per-packet copy takes place, which is required to move payload data from Napatech-memory to ZC memory. Keep this in mind!

It describes that if we use PF_RING ZC then 1 copy happens. Could you please explain this?

-Iqbal

Observations:
We tried to execute below command to achieve 10G traffic, but as you can see in 
log it gradually decreases and becomes stable at 2.6G traffic.
# disk2n -i nt:0 -m /tmp/playpcap.txt -c 1 -w 2 -S 3   -b 18000 -C 1024 -I 450
