[Mono-list] String comparisons slow

[David S]

I think there is another problem that is hidden behind all the complexity of
your program. I can tell you this, it isn't string comparer.

using System;
using System.Collections.Generic;
using System.Diagnostics;

namespace StringCompare
{


public class MainClass
{

public static void Main()
{
List<List<string>> lists = new List<List<string>>();
Random r = new Random();
for ( int i=0; i < 4; i++ ) {
lists.Add( new List<string>() );
for ( int j=0; j < 40000; j++ )
lists[i].Add( r.Next().ToString() );
}
Stopwatch watch = new Stopwatch();
watch.Start();
foreach ( List<string> list in lists )
list.Sort();
watch.Stop();
Console.WriteLine( watch.Elapsed );
}
}
}

OUTPUT = 00:00:03.1364747

That being said I think its how you set up your threading. It could
very easily be how Mono handles Threads (sleeping and such). Honestly, I
have no idea, but I am intrigued.
