post_screencap获取截图的耗时太长

[SCzfdf]

经过日志打印发现每次执行间隔在400毫秒左右. 请问这正常吗?
我现在是使用python执行, 如果换其他语言执行速度会不会快一些
以下是定义的流水线和触发器.

pipeline

"screenshot": {
        "action": "Custom",
        "custom_action": "screenshot_action",
        "pre_delay": 0,
        "post_delay": 0
    },

python_action

class ScreenshotAction(CustomAction):

    def run(self,
            context: Context,
            argv: CustomAction.RunArg) -> bool:
        """
        截图线程
        """
        img = context.tasker.controller.post_screencap().wait().get()
        logging.debug("ScreenshotAction post_screencap")
        RDContext.set_screenshot(img)

        return True
