Re: performance question

Hoisting manually, we finally arrive at:

import java.io.*;

public class Test
{
    public static void main(String[] args) throws java.io.IOException
    {
        BufferedOutputStream out = new BufferedOutputStream(System.out);

        byte[] s1 = "abcdefghijk ".getBytes();
        byte[] s2 = "\n".getBytes();

        for (int i = 0; i < 1000000; i++) {
            out.write(s1);
            out.write(Integer.toString(i).getBytes());
            out.write(s2);
        }
    }
}

Now this only takes 0.947s! Incredible, several times longer now and still
several times slower than any decent language!

In summary, what we have learned is that for the love of God (TM) don't use
Java if performance is at all important for your work. This doesn't just
apply to IO either: Java is very slow at a wide variety of vitally-
important tasks, e.g. allocation.
