How CPU Time is Spent inside Envoy Servers (using OpenResty XRay)

Try out OpenResty XRay for free: https://openresty.com/en/xray/ In this tutorial, we will walk through how to use OpenResty XRay to quantitatively analyze the CPU time consumption in the Envoy servers online. We will show the C++ code paths that consume the most CPU time. These hot code paths are obtained by OpenResty XRay automatically analyzing and interpreting the C++ language-level CPU flame graphs. It tries hard to minimize the performance impact, thus making it ideal for production environments sensitive to performance overhead and latency. At least for simple scenarios, we can see that Envoy is much less efficient than OpenResty and Nginx. Text version of this tutorial: https://blog.openresty.com/en/envoy-c... OpenResty XRay is a dynamic-tracing product that automatically analyzes your running applications to troubleshoot performance problems, behavioral issues, and security vulnerabilities with actionable suggestions. Under the hood, OpenResty XRay is powered by our Y language, targeting various runtimes like Stap+, eBPF+, GDB, and ODB, depending on the context. OpenResty XRay is a truly non-intrusive dynamic analysis, which does not require installing any special modules or plugins in the target application, does not require recompiling the target application, and does not even require restarting the running process.
