Code Tuning and Optimization

  1. You are given a C# application "homework.zip" 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 screenshot 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.
  • Write a program to compare the performance of add, subtract, increment, multiply, divide for int, long, float, double and decimal values.
  • Write a program to compare the performance of square root, natural logarithm, sinus for float, double and decimal values.
  • * Write a program to compare the performance of insertion sort, selection sort, quicksort for int, double and string values. Check also the following cases: random values, sorted values, values sorted in reversed order.
