Progressive Tooling VS DTrace

• Efficiency
  Progressive tooling allows for multiple operations to be performed in a single press stroke, significantly increasing production speed and reducing cycle times.
• Cost-effectiveness
  By combining multiple processes in a single tool, progressive tooling reduces labor and equipment costs associated with handling and transferring materials between different stations.
• Consistency
  The use of progressive tooling provides a high level of precision and uniformity across all manufactured parts, ensuring consistent quality in production runs.
• Space-saving
  Since progressive tooling incorporates several operations into one tool, it reduces the need for multiple machines and workstations, saving floor space in manufacturing facilities.

Possible disadvantages

• High Initial Investment
  The cost of designing and manufacturing progressive tooling is typically higher compared to single-operation tools, which can be a barrier for small manufacturers or those with limited budgets.
• Complex Maintenance
  Due to the intricate design and integration of multiple operations, maintenance and repairs of progressive tooling can be more complex and time-consuming compared to simpler tools.
• Limited Flexibility
  Once a progressive tool is designed and built, making changes to the tool or the processes it performs can be difficult and costly, limiting flexibility in responding to changes in production requirements.

• Comprehensive Observability
  DTrace provides a comprehensive view of system behavior by observing metrics across various layers, including the operating system, hardware, and applications.
• Real-time Analysis
  It allows for real-time tracing and diagnosing, which is critical for identifying performance bottlenecks as they occur.
• Low-Overhead
  DTrace is designed to have minimal impact on system performance, making it suitable for use in production environments.
• Dynamic Instrumentation
  It can dynamically enable and disable probes in a live system, which allows detailed monitoring without restarting the system or applications.
• Cross-platform Support
  Originally developed for Solaris, DTrace has been ported to other operating systems like FreeBSD and MacOS, extending its usability.

Possible disadvantages

• Complexity
  DTrace's powerful capabilities can make it complex to learn and use effectively, especially for those unfamiliar with its scripting language.
• Limited to Supported Platforms
  DTrace is not available on all operating systems, limiting its use to those systems that support it.
• Security Concerns
  Since DTrace can access many parts of the system, there are potential security implications if not properly managed and secured.
• Limited GUI Tools
  While DTrace is command-line oriented, it lacks advanced built-in graphical interfaces, which can be a drawback for users who prefer visual data representation.
• Potential for Misuse
  Improper use of DTrace can lead to system instability or performance problems, particularly if inexperienced users enable extensive probes.

  I believe that macOS still ships with DTrace; Xcode Instruments was originally built on top of it. https://dtrace.org (Some people find it easier to write a one-line script that reports the timings that they need; I don't know if it... - Source: Hacker News / over 2 years ago
