Pyro Caml Continuous Profiler for OCaml
The developers of Semgrep have released Pyro Caml, a continuous profiler designed specifically for the OCaml programming language. This tool allows developers to monitor performance in production environments, filling a gap in the OCaml ecosystem.
Why it matters
Continuous profiling is essential for maintaining the reliability and performance of large-scale industrial software systems.
The core SAST engine of Semgrep is written in OCaml. There are a lot of good technical and historical reasons for this that I’ll leave for another time. An important consequence of using a language with a (relatively) small ecosystem like OCaml is that there aren’t a lot of libraries for things like observability, which are critical for running industrial software like Semgrep on hundreds of thousands of code repositories, and keeping it both reliable and performant.
