java JOGL启动时间太长
我正试着对慢跑有一点了解，但似乎我甚至无法让这个项目正常启动
@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，没有发生太多事情。。。代码可以工作，但启动大约需要15秒。我使用-Xprof运行它，结果是以下输出：

（请注意，GLProfile#获得~13秒的区块！）
我已经测试了HelloTriangle，这导致了相同的结果（除了一切都运行得非常好、FPS恒定等）
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不同的是，我对FPS/纹理没有任何问题，只是启动程序需要太长时间
