测试代码和打印信息。。
切换页面，看打印信息，220MS - 290MS  画页面耗费约70MS  300MS - 770MS执行耗费时间约470MS，在PAINT一次 800MS - 50MS执行耗时约250MS，画面就显示出来。大概470+250=720MS左右完成页面切换完成。这里加了停止任务调度。如果加上任务调度。打印信息如下：

这里有个现象，WM_PAINT会执行两次，画面才能建立。

rt_enter_critical对页面影响不大。
多线程运行emwin，没有的。
1，
```
    rt_thread_init(&thread1,
                   "thread1",
                   thread1_entry,
                   RT_NULL,
                   &thread1_stack[0],
                   sizeof(thread1_stack), 21, 5);
    rt_thread_startup(&thread1);
```
2，
```

```
/*********************************************************************

WM_HWIN CreateWindow(void) {
  WM_HWIN hWin;
	
  hWin = GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), &_cbDialog, WM_HBKWIN, 0, 0);
	
	hTimer = WM_CreateTimer(hWin,0,50,0);

}

减少控件的数量，速度能快

Mon Feb 14 09:50:18 2022 590 mseconds
Mon Feb 14 09:50:18 2022 590 mseconds
1-Mon Feb 14 09:50:18 2022 600 mseconds
WM_PAINT-Mon Feb 14 09:50:18 2022 750 mseconds
2-Mon Feb 14 09:50:18 2022 880 mseconds

耗费时间10ms+150ms+130ms < 300ms，控件加多了，费时间。
