Unbalanced CPU core usage


I need a configuration recommendation to balance the CPU cores, I’m using Intel® Xeon® E5-2697 v4 18 Core 36 Threads but at this time when I use it for the distribution of around 1500 users with PPPOE and QinQ the core usage is uneven. I have activated rps on each interface. but only 8 cores that load the cpu used.

can be seen from the use above for cpu that work more on cores 9-15. can it be made evenly for the use of the cpu?

Thank you.
