你好。我正在使用DPDK工作。我编写了我的程序，它运行良好。但是我在循环方面遇到了问题。除了使用while循环无限运行函数之外，DPDK是否有其他选项？当我使用while循环时，我只能获得每秒4百万数据包的单个CPU核心。

Hello. I am working on DPDK. I have written my program and it's working
fine. However, I am having a problem with the loop. Is there any option in
DPDK other than using a while loop to run the function infinitely? When I
use a while loop, I only get 4 Mpps on a single CPU core.
