Code Tuning and Optimization Homework

Task 1. Solar System

• You are given a C# application SolarSystem which displays an animated 3D model of the Solar system.
  • Use a profiler to find the places in its source code which cause significant performance degradation (bottlenecks).
  • Provide a screen-shot of the profiler’s result and indicate the place in the source code where the bottleneck resides (name of the file, line of code).
  • Make a quick fix in the source code in order to significantly improve the performance.
  • Test the code after the fix for correctness + performance.

Task 2. Compare simple Maths

• Write a program to compare the performance of:
  • add, subtract, increment, multiply, divide
• for the values:
  • int, long, float, double and decimal

Task 3. Compare advanced Maths

• Write a program to compare the performance of:
  • square root, natural logarithm, sinus
• for the values:
  • float, double and decimal

Task 4.* Compare sort algorithms

• Write a program to compare the performance of:
  • insertion sort, selection sort, quicksort
• for the values:
  • int, double and string
• Check also the following cases:
  • random values, sorted values, values sorted in reversed order.
