Re: [vpp-dev] Vpp_main running at 100% CPU
Hi,
It is running in a CentOS 7 VM, no PCI passthrough. I think I left the vhost
interface created during some play test.
I can try vpp_lite and see how it performs in this scenario.
Thank you very much for your suggestion!
Best Regards,
Miguel Ángel.

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.
