New comment by tanelpoder in "How Do I Profile eBPF Code?"

tanelpoder — Tue, 28 Jul 2026 18:30:13 +0000

Last month I wrote a tool called "brr" - eBPF Runtime Reporter and Profiler. It displays a bpftop-like eBPF program summary, but you can also zoom into any program to see its source code lines (if available) and profile the eBPF program activity and any kernel code activity called/caused by the eBPF program for the full picture of where your eBPF program time/latency is spent.

I wrote it mostly with Codex for my own use, but just pushed the latest release to GitHub (with screenshots) in case anyone else is interested:

Show HN: Profiler and Runtime Reporter for eBPF programs (brr)

tanelpoder — Thu, 18 Jun 2026 07:57:17 +0000

Here's something I've been using for eBPF program profiling & optimization purposes and just published it as it has made my "performance nerd life" easier.

This is a tool for profiling eBPF programs themselves, probe->kernel activity, interactions with shared hash maps, etc.

Since eBPF programs are pieces of machine code residing in (kernel) address space, you could profile them with standard perf just like any other kernel function. However, perf alone won't show you other useful metrics like number of executions and average eBPF program runtime, like bpftop does. Also, I want an easy way to map CPU samples to original source code lines, where possible.

I wanted to unify both approaches, display the bpftop-style call count & probe latency, with the ability to drill down inside where the eBPF program spends most of it's time.
