Hi, Excuse me for the misunderstanding. Most probably this is not an issue in VPP. In the mentioned 'previous version of vpp (git version 45207e0fb2) the af_packet_create_v2 api was used, so the memory increase is expected. So, the question had lapsed.

I experienced an increase in memory allocation related to af_packet v3. VPP is built from source from git version: e416893a5. The AF_PACKET interface is created by the go bin-api call AfPacketCreateV3 (invoking af_packet_create_v3 api call in VPP). The amount of memory assigned to an af_packet socket appears to be 135MB per af_packet socket. In VPP based on git version 45207e0fb2 the memory assigned to an af_packet socket was around 20MB. Is this memory allocation increase intentional? If not is it a known issue? Any workaround or patch exist (if it is a bug and it was fixed)? Thanks in advance, Laszlo
