Analysis

Overview

The goal of this task is to develop a strategy for dealing with performance issues in the ProLib.
The focus in this task is on performance measured in time. There's a separate task for memory management and optimizations.

Task requirements

• Devise an overall concept how to measure performance:
  • what is to have its performance measured?
    • performance tests, written for specific measurements
    • unit tests
    • other?
  • how to measure it?
    • by a self-written utility, which will be developed by our team, or
    • some kind of a profiler
      
    Argue on the two possibilities and provide details on the self-written utility or propose concrete profiler to use.
  • how to identify and deal with bottlenecks
  • generating performance reports
    • what to include in the reports
    • how often to generate them
    • where to upload them
    • how to generate them
      • with some sort of script?
      • can these reports be integrated with Maven
  • how to identify performance regressions
  • where and how to apply algorithmic optimizations
• According to this concept locate concrete problems and propose solutions to them
• Write appropriate tests for these problems

Task result

• Description of the developed concept in this wiki page
• List of concrete problems and solutions
• Possibly new code which fixes located problems
• Possibly new tests which correspond the located problems

Implementation idea

• Look for a suitable profiler in the JDK

• Explain the problems and proposed solutions
• Run the newly created unit tests, if any
