CPU is high load when received heavy load UDP packets

Dear NXP engineers,

I'm developing network device base on LX2160A chip, now I'm facing the issue when system receives heavy load UDP packets. Using perf tool  for testing and bind it to one core, I can see that the CPU consumption for iperf is 62%, and you can see it on the image it's really high load on System time.

May I know this issue is normal for the platform LX2160A?

What should I do to improve CPU consumption in this case?

Hardware: LX2160A-RDB reference design board
BSP: LSDK 20.04_290520
OS: Ubuntu 18.04

Thanks.
