The Code Profiler is a Business Manager tool used to analyze server-side run-time performance and script execution times. It helps developers identify performance bottlenecks by tracking metrics like execution time and hit counts across different modes.

Core information
  • Access the tool via Business Manager under Administration > Operations > Code Profiler.
More details and nuances
  • Wait Time represents the portion of Elapsed Time not spent processing, such as I/O operations or concurrency locking, indicating external waits rather than code execution.
