[jdom-interest] Build From a String Performance Problem?

[Michael Skells]

It is instantanious for me after the first run

On the first run there is the overhead of classloading, JIT compilation
etc

public class Main extends Object {
    
    /** Creates new Main */
    public Main () {
    }
    
    /**
     * @param args the command line arguments
     */
    public static void main (String args[]) {
        try{
            long time = System.currentTimeMillis();
            String sXML = "<TestX><Val1>some value</Val1></TestX>";
            Document doc = new org.jdom.input.SAXBuilder().build(new
StringReader(sXML));
            System.out.println((System.currentTimeMillis() - time));
            time = System.currentTimeMillis();
            doc = new org.jdom.input.SAXBuilder().build(new
StringReader(sXML));
            System.out.println((System.currentTimeMillis() - time));
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
    
}

gives the results
