我正试图进入JOGL，但似乎我甚至无法让程序正常启动。
@SuppressWarnings("serial")
public class Test extends GLJPanel implements GLEventListener {
public static final void main(final String[] args) {
final long startTimeMillis = System.currentTimeMillis();
final GLProfile profile = GLProfile.get(GLProfile.GL4);
System.out.println("GLProfile#get -> " + (System.currentTimeMillis() - startTimeMillis));
final GLCapabilities capabilities = new GLCapabilities(profile);
final JFrame frame = new JFrame(Test.class.getName());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final Test t = new Test(capabilities);
frame.add(t);
frame.setVisible(true);
frame.pack();
frame.setLocationRelativeTo(null);
}
public Test(final GLCapabilities capabilities) {
super(capabilities);
super.setPreferredSize(new Dimension(960, 640));
super.addGLEventListener(this);
}
@Override
public final void init(final GLAutoDrawable drawable) {}
@Override
public final void dispose(final GLAutoDrawable drawable) {}
@Override
public final void display(final GLAutoDrawable drawable) {}
@Override
public final void reshape(final GLAutoDrawable drawable, final int x, final int y, final int width,
final int height) {}
}
正如你所看到的那样，没有太大的进展...代码可以工作，但需要大约15秒才能启动。我使用-Xprof运行它，结果如下：

（注意GLProfile＃get块为~13s！）
我已经测试HelloTriangle导致相同的结果（除了一切都工作得很好，不断的FPS等）。
我做错了什么？顺便说一下，我在Windows 10上使用Nvidia GTX。
与JOGL Jar runs fine on my development machine, but slowly on others? Even if they have better hardware不同，我对FPS /纹理没有任何问题，只启动程序需要太长时间。
