Ternary operator is twice as slow as an if-else block?

Question

I read everywhere that ternary operator is supposed to be faster than, or at least the same as, its equivalent if-else block.

However, I di

Answer 1

Run without debugging ctrl+F5 it seems the debugger slows down both ifs and ternary significantly but it seems it slows down the ternary operator much more.

When I run the following code here are my results. I think the small millisecond difference is caused by the compiler optimizing the max=max and removing it but is probably not making that optimization for the ternary operator. If someone could check the assembly and confirm this it would be awesome.

--Run #1--
Type   | Milliseconds
Ternary 706
If     704
%: .9972
--Run #2--
Type   | Milliseconds
Ternary 707
If     704
%: .9958
--Run #3--
Type   | Milliseconds
Ternary 706
If     704
%: .9972

            int[] randomSet = new int[1000]; //a
            for (int i = 0; i < 1000; i++)   //n

                        max = max; // I think the compiler may remove this but not for the ternary causing the speed difference.
