Background

Users often (rightly) request performance improvements to improve usability. Developers often have ideas about code that they suspect is consuming the time, and begin to code. But sometimes performance bottlenecks are in unexpected places that can only be quantified with detailed performance assessment tools. These tools can also help measure the impact of code changes.

Topics

  • Performance assessment tools: survey of methods and tools across platforms
  • Demo of the Instruments package on Mac to evaluate time usage in slicer4
  • Review of time-critical points in slicer (as time permits)
    • application startup
    • loading data
    • changes to hierarchy visibility
    • DICOM loading
  • Discussion of User Priorities for Performance Optimization
