Yandex Open-Sources Perforator: Continuous Profiling Without Production Performance Hit
2025-02-01
Yandex has released Perforator, an open-source continuous profiling tool built on eBPF technology. Perforator collects CPU profiles from production environments without impacting performance. Already deployed on tens of thousands of Yandex servers, it helps developers identify and resolve performance bottlenecks. Supporting languages like C++, C, Go, and Rust (with experimental Java and Python support), it features scalable storage, a user-friendly query language and UI, and sPGO profile generation for Profile Guided Optimization (PGO). Perforator boasts minimal resource consumption and is easily deployable on various environments, from laptops to Kubernetes clusters.
