TIL that when top isn't granular enough for CPU profiling,

perf record -g -p <PID> -- sleep 10 && perf report

will generate call graphs to show exactly where CPU cycles are spent. Very handy.

🌗 使用 bpftrace 探索語言運行時
➤ 透過動態追蹤改善 JavaScript 引擎效能
✤ mgaudet.ca/technical/2025/5/28
這篇文章描述了作者使用 eBPF 和 bpftrace 工具來分析 JavaScript 引擎 SpiderMonkey 的運行時行為。作者成功利用 bpftrace 追蹤 `Rooted` 建構子的呼叫來源，協助找出可以優化程式碼的地方，例如透過使用 `RootedTuple` 減少不必要的呼叫。此過程不僅展示了 bpftrace 的強大功能，也突顯了在效能分析中尋找問題並解決問題的實用價值。
+ 這篇文章寫得真好，清楚地解釋了 bpftrace 的應用，讓我不斷想嘗試用它來分析自己的程式碼。
+ 感覺 bpftrace 是一個非常強大的工具，可以深入瞭解程式的運行機制，但學習曲線可能有點陡峭。

Looking for a way to profile #coverage for functional tests transparently I built github.com/maxgio92/xcover

It generates a function coverage report. Using #ebpf uprobes it supports ELF binaries and it's cross-language compatible.

@robertpi the current state of the industry means that a lot of energy and resources get poured in one particular field. Outside that* (you know.. the fancy parrot), I find #ebpf super interesting and worth exploring.
So far most of the interesting things built on top seem to be in the networking / CNI space (Cillium is fun if you are into the ecosystem) . And ofc observability, I've been trying to roll some things out for basic black box tracing (engineering resources being scarce). Maybe I am a bit late to the party, but I find this exciting and keep coming up with ideas and problems someone already solved :blobfoxcomputerowonotice:

Other than that it's learning things which already exist. Some good ideas in the thread 👌
