OCaml developers often struggle to understand where allocations and boxing occur, hindering performance improvements. This Skill provides a structured approach to instrument code with memtrace to reveal allocation hotspots and guide targeted optimizations.
Use Memtrace to instrument your OCaml project: add Memtrace.trace_if_requested () at program startup, build with dune, run with MEMTRACE=trace.ctf, and analyze the resulting trace to locate allocation hotspots.

You can profile OCaml allocations by adding Memtrace.trace_if_requested () at program startup, building with dune, running benchmarks with MEMTRACE=trace.ctf, and analyzing the resulting trace to locate allocation hotspots.
Tracing boxing overhead in OCaml is done by applying Memtrace instrumentation to targeted benchmarks, running them with the MEMTRACE environment variable enabled, and analyzing the trace data to isolate boxing overhead and function hot paths.
You validate OCaml optimizations by running Memtrace-instrumented benchmarks before and after code changes, capturing allocation traces, and comparing hotspot data to confirm reductions in boxing overhead and allocations.
Yes, you can use dune to build OCaml projects with Memtrace instrumentation by integrating the trace_if_requested call at startup and gating the trace collection using the MEMTRACE environment variable during benchmark execution.
Visualizing Memtrace allocation data involves loading the generated trace.ctf files into memtrace-viewer or similar hotspot tooling, which graphically displays function hot paths and boxing overhead to drive data-informed improvements.
