In the example shown -VPP is configured with 2 workers. The main thread is also configured to run on a separate CPU. The -stats thread will always run on CPU 0.

If the system is running many processes -it may be necessary to isolate CPUs for VPP or other processes. - -Huge Pages ----------- - -As default when VPP is configured the number of huge pages that will be configured will be 1024. -This may not be enough. This section will show the total system memory and how many are configured. - - -Devices -------- - -In the devices section we have the "Total Number of Buffers". This utility allocates the correct -number of buffers. The number of buffers are calculated from the number of rx queues. - -VPP will not use links that are up.
