最近发现 appium 执行时响应特别慢，分钟级别的响应。
日志如下：

可以看见 46 分发出请求，53 分才给出未找到的响应，同时有提示：Failed to locate element. Clearing Accessibility cache and retrying.
多次重启 appium-server 会有时候没有这个问题，但问题出现的比较频繁。

环境：
appium server 1.6.4
client 4.0.0
jdk 1.8
模拟器用的 genymotion 安卓版本 4.3
查找部分代码如下：

String str1 = "new UiSelector().text(" + "\"" + text + "\")";
WebElement el;
try {
    el = driver.findElementByAndroidUIAutomator(str1);
} catch (Exception e) {
    el = null;
}
