C# simple program slow
0
I have a simple program written in C# and I ran it in two laptops same specs but one has Windows 8 and the other has Windows 10 and I measure the time in milliseconds and get the difference between the start and the end but in windows 8 it takes approx 1k milliseconds while in windows 10 it takes approx 15k milliseconds. Why this huge difference?
This is the code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp1
class Program
static void Main(string args)
long milliseconds = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;
Console.WriteLine(milliseconds);
for(int i = 0; i < 100000000; i++)
if(i%10000==0)
Console.WriteLine(i);
long milliseconds2 = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;
Console.WriteLine(milliseconds2);
Console.WriteLine("Diff " + (milliseconds2-milliseconds));
Console.ReadLine();

Are both operating systems 64 bit? Do they both have the same version of .Net installed?

I would guess you are actually measuring the Console output speed.

Have you tried them just once? Or measure these times as an average of multiple runs?

@MatthewWatson yes both are 64 bit with the same .Net version

Sorry to be so blunt but: Your code effectively does nothing. Your measurement is therefore totally meaningless. Put some typical workload in the loop and then you may get more useful results. My guess: The will not be a consistent result let alone any difference to worry about
