Research direction

No files, tests, or entry points are identified in the issue, so begin by locating where tlparse collects compiled-frame metrics. The work is complete when compiled frames report hit counts and runtime timings, including behavior across multiple recompilations.

Written by the indexing model from the issue text.

Description

tlparse currently is a compile time only metrics collector. However, there is a small amount of runtime information that I think would be really useful:

  1. How many times a particular compiled frame was hit. In particular, if we recompile multiple times, we might be interested to know how hot each of the particular recompiles are, which tells you if there is some warmup / unspec thing going on, or if there is legitimate multiple dispatch going on
  2. How quickly the compiled frames run, a sort of poor man's profiling, but mostly I just want to see the timings from a compiled products perspective, as opposed to the usual performance trace perspective
