Ternary ? operator vs the conventional If-else operator in c# [duplicate]

by

I ran 100 million Ternary Operators and 100 million If-Else statements and recorded the performance of each. Here is the code:

Stopwatch s = new Stopwatch();
// System.Diagnostics Stopwatch
int test = 0;
s.Start();
for(int a = 0; a < 100000000; a++)
    test = a % 50 == 0 ? 1 : 2;
s.Stop();

s.Restart();
for(int b = 0; b < 100000000; b++)
{
    if(b % 50 == 0)
        test = 1;
    else
        test = 2; 
}
s.Stop();

Here is the results (ran on an Intel Atom 1.66ghz with 1gb ram and I know, it sucks):

  • Ternary Operator: 5986 milliseconds or 0.00000005986 seconds per each operator.

  • If-Else: 5667 milliseconds or 0.00000005667 seconds per each statement.

Don’t forget that I ran 100 million of them, and I don’t think 0.00000000319 seconds difference between the two matters that much.
