Traffic is 24/24 and continuous.
There is some regular activity peaks around 07:00 or 14:00 (end users
connect to our servers so it's always quite random).


Here is the average for the exact same minute:
- from pcap files:
87 746 306 bps
- from ifpps:
100 304 634 bps (12538079,25 bytes)


Almost every value from ifpps is greater than the one captured with
netsniff-ng (but not all of them).

Around the max from iffps values are:
- ifpps (bps):
98753008
235113328
119650144

- netsniff-ng (bps):
105770240
93430552
112247968


So I really think that the value fetched from ifpps (/proc/net/dev)
are greater than netsniff-ng but I don't get why (again I could be
wrong).

I don't see any packets dropped or any errors on the interface.

I disabled gro, gso and tso with ethtool on the interface but no changes.
