Am facing severe packet loss while performing Packet forwarding using Packet gen DPDK. Any packets equal to 500 and above that results in huge packet loss. I have learnt about DPDK architecutre from its main site. I have changed MBUF values and also cahce size, but still no luck. Any help would be much apprecitated. I am uploading every single image to get an idea on what I am doing.

There many factors affecting performance. As O recollect we had walked through the same in 'stackoverflow and Skype'. For better understanding share details of system, vcpu pinning, huge page backing, please use kvm qux or xen than virtual box. If you still want to use virual box use pcie pass through rather than tap port for vitio – Vipin Varghese Dec 31 '20 at 03:36

@peterh-ReinstateMonica So Am I not allowed to post network related query here? – Saif Ullah Jan 04 '21 at 06:00
@SaifUllah Yes, you can. – peterh Jan 04 '21 at 08:46
@SaifUllah the issue is not in DPDK but your environment. Please edit and modify with the right information. – Vipin Varghese Jan 04 '21 at 10:41
@SaifUllah https://stackoverflow.com is for entirely programming questions. https://unix.stackexchange.com or https://askubuntu.com is for unix/linux/ubuntu questions. https://networkengineering.stackexchange.com is for (professional) network management questions. – peterh Jan 04 '21 at 12:19
