CPU Benchmark - single core speed test with Fibonacci Sequence in Dart

In this short article, I would like to show Fibonacci Sequence test that is run on a single core. The test source code was converted from C++ to Dart - check source article.

Example test.dart file:

void main() {
  int tmp, a = 0, b = 1;

  print('Started!');
  
  var t1 = DateTime.now();

  for (int i = 0; i < 10000; ++i) {
    for (int j = 0; j < 1000000; ++j) {
      tmp = b;
      b = a + b;
      a = tmp;
    }
  }

  var t2 = DateTime.now();
  var dt = t2.millisecondsSinceEpoch - t1.millisecondsSinceEpoch;

  print('Finished!');
  
  print('Result: ${b}');
  print('Time: ${dt}s');
}

Test compilation:

dart compile exe test.dart

Test running:

./test.exe

Example output:

Started!
Finished!
Result: -1667179358074339043
Time: 4.3180000000000005s

Note: Result: -1667179358074339043 was printed only to prevent against automiatic optimization.
