[Mono-devel-list] Integer and Floating point formatters

[Atsushi Eno]

Okay, I tried this simple test.

using System;
public class Test {
        public static void Main () {
                DateTime dt = DateTime.Now;
                for (int i = 0; i < 500000; i++)
                        if (i.ToString () == null)
                                Console.WriteLine ("heh.");
                Console.WriteLine (DateTime.Now.Ticks - dt.Ticks);
        }
}

[old one]
$ mono ./perf.exe
6810000

[new one]
$ mono ./perf.exe
16530000

mono --profile results are:
http://monkey.workarea.jp/tmp/20050130/perf-original-simple.txt
http://monkey.workarea.jp/tmp/20050130/perf-kazuki-simple.txt

So the result was still worse. It went nearly 2.5x slower and
nearly 4x memory consumptive. I personally don't like this loss.
It won't be late after some optimization effort is done.
