Hi Miguel, Most your time is being spent in dpdk_input and vhost_user_input. Are you running VPP in a VM or on the host? I ask because vhost_user_input suggests you are running on the host?
If you are running in a VM and you are using software interfaces (no PCI passhrough) you might try using vpp-lite with the af_packet interface instead of dpdk_input as you will likely get similar performance without DPDK polling.

Can you do a 'show run' in vppctl to see where time is being spent.

At the moment I'm running vpp 1609 with honeycomb in Centos7, as a VirtualBox VM. Once VPP is started, 'top' command shows vpp_main process taking 100% CPU in one of the cores and never goes down. Is this normal? I have VT-x/AMD-V/PAE/NX extensions activated. Thank you, Best Regards, Miguel Ángel.
