in-kernel verifier ensures that BPF programs are safe to run and a JIT compiler converts the bytecode to CPU architecture specific instruc�ons for na�ve execu�on efficiency. BPF programs can be run at various between 10 seconds and 30 minutes or 12 hours for LRU based maps. This should automa�cally op�mize CPU consump�on as much as possible while keeping the connec�on tracking table u�liza�on below 25%. If needed and bpf-ct-global-tcp-max can be increased. Se�ng both of these op�ons will be a trade-off of CPU for conntrack-gc-interval , and for bpf-ct-global-any-max and bpf-ct-global-tcp-max the amount of

性能提升的主要表现： • 不同场景下，不同程度地降低了 网络数据包的“转发延时” • 不同场景下，不同程度地提升了 网络数据包的“吞吐量” • 不同场景下，不同程度地降低了 转发数据包所需的“ CPU 开销” eBPF 简介 eBPF 技术 在 Linux kernel 3.19 开始被 引入，可在用户态进行 eBPF 程序编程，编译 后，动态加载到内核指定的 hook 点上，以 VM 方式安全运行，其能过通过 LoadBalancer service 的解析和转发，其转发性能能比肩 DPDK 技术，且能节省大量CPU资源 当 PPS 压力越大，提升效果越发显 著，相比 kube-proxy，测量得出以下 效果： 1. TC 转发方式，在10Mpps input压 力下提升 1 倍的吞吐量，在2Mpps 压力下，节省了30%的CPU利用率 2. XDP的性能上限极高，可能是 TC 的 10 倍左右 raw PREROUTING
