Suggestion

Further improvements on #40460:

  • Tracing from tsserver
  • Post-processing script to handle size & unterminated dumps
  • Optimize tracing._ calls (done via tracing?._)
  • Using sampling to reduce tracing costs
  • Possibly use a proper sampling (worker) thread
    • Filter include/exclude command-line selection (not needed if sampling thread works)
  • Adjust expression source locations in post processing script
  • Improve UI by embedding tracing as a library (since there are no better visualizers)
  • Consolidating data and metadata into a single file
  • Enabling streaming gzip?
