Hello,
Hard to tell without info about the various nodes etc.
The best should be to look at the "show run" output:
https://s3-docs.fd.io/vpp/23.02/gettingstarted/troubleshooting/cpuusage.html#vpp-cpu-load
When traffic run through, do "clear run" and then "show run" in the VPP cli to
see where cycles are spent.
