Sadly I found out that, at least by default (which is what most mono application use), mono does not give better performance when using Math.Min|Max. # using Math.Min|Max [EMAIL PROTECTED]:~/src/bugzilla> mcs minmax.cs [EMAIL PROTECTED]:~/src/bugzilla> time mono minmax.exe 11727587164160 real 0m23.916s user 0m23.745s sys 0m0.092s # using manually inlined code [EMAIL PROTECTED]:~/src/bugzilla> mcs minmax.cs [EMAIL PROTECTED]:~/src/bugzilla> time mono minmax.exe 11727587164160 real 0m16.622s user 0m16.445s sys 0m0.068s Source code: using System; class Program { static void Main (string[] args) { long value = 0; for (int i = 0; i < Int16.MaxValue; i++) { for (int j = Int16.MaxValue; j >= 0; j--) { #if false value += Math.Max (i, j); value -= Math.Min (i, j); #else value += (i > j) ? i : j; value -= (i < j) ? i : j; #endif } } Console.WriteLine (value); } } Another test (my original one), where the min/max code was inside a method (to clamp a value) showed similar results. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
