Overhead of eBPF Programs Bryce Kahle, Datadog October 28, 2020 Why should I profile eBPF programs? CI variance tracking Tools kernel.bpf_stats_enabled kernel.bpf_stats_enabled sysctl – Added in kernel collection for all eBPF programs – exposes total run_time_ns and run_cnt – Use cases: – Benchmarking + CI/CD – Sampling profiler in production How does it work? – Adds ~20ns of overhead per run Two ways
