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 map 存储结 构存储数据，能通过 map 同用户态程序交互， 最终实现内核数据进行修改，或者影响内核处 理请求的结果，或者改变内核处理请求的流程。

deploy Hubble Relay and the UI as follows on your existing installation: Installation via Helm If you installed Cilium via helm install, you may enable Hubble Relay and UI with the following command: --reuse-values \ --set hubble.listenAddress=":4244" \ --set hubble.relay.enabled=true \ --set hubble.ui.enabled=true On Cilium 1.9.1 and older, the Cilium agent pods will be restarted in the process. Installation installed Cilium 1.9.2 or newer via the provided quick-install.yaml, you may deploy Hubble Relay and UI on top of your existing installation with the following command: kubectl apply -f https://raw.githubusercontent
