Open-sourced back in January was the Yandex Perforator as a new software project for [1]uncovering code inefficiencies and potentially "save billions of dollars" in expenses. Perforator has continued evolving since its open-source announcement and out today is Perforator 0.0.5 as the latest milestone.

Perforator employs continuous profiling and eBPF programs to uncover coding inefficiencies while being light enough to run on production servers. Perforator can work across C++, Go, Rust, Java, Python, Node.js, and other programming languages while also making use of Profile Guided Optimizations for tapping greater performance gains.

Perforator 0.0.5 brings a number of fixes as well as profiling enhancements, UI improvements for interacting with the collected data, and more.

Perforator 0.0.5 has also changed the source code license from being under the MIT license to now using the Apache 2.0 license. Additionally, it's no longer necessary to sign a Contributor License Agreement (CLA) for submitting pull requests to this open-source project. Details on the change to dropping the CLA can be found via [2]this commit .
