Question

我是JavaFx和JavaScripting的新手

我的JavaFx应用程序（显示HTML / JavaScript页面）可测量不同版本的JX浏览器的性能。

当我手动执行 Run 按钮时，似乎JX Bowser 6.23的速度比6.21慢。

我在做什么错？我应该怎么做才能提高性能。

版本（6.23）-10次执行时间（以毫秒为单位） 3879，3637，4483，3583，3565，3656，3748，3834，3895，3799

中位数3773.5，平均3807.9，最大4483，最小3565

版本（6.21）-10次执行时间（以毫秒为单位） 3581、3326、3257、3273、3217、3299、3284、3304、3352、3323

中位数3301.5，平均3321.6，最大3581，最小3217

示例代码如下：

JavaFX代码

sample.fxml

<?import javafx.scene.layout.AnchorPane?>
<AnchorPane fx:id="pane" fx:controller="sample.Controller"
            xmlns:fx="http://javafx.com/fxml">
</AnchorPane>

Main.java

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Test JX Browser Performance");
        primaryStage.setScene(new Scene(root, 1800, 1000));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Controller.java

public class Controller implements Initializable {

    private static final Logger LOGGER = LogManager.getLogger(Controller.class);

    @FXML
    public AnchorPane pane;

    public static String pagePath = new File("src/sample/html/testJXBrowserCode.html").getAbsolutePath();;

    public void initialize(URL location, ResourceBundle resources) {
        BrowserPreferences.setChromiumSwitches(
                "--enable-experimental-canvas-features=true",
                "--num-raster-threads=4",
                "--max-tiles-for-interest-area=512",
                "--disable-web-security",
                "--allow-file-access-from-files",
                "--headless",
                "--remote-debugging-port=9222");

        final Browser browser = new Browser();
        final BrowserView browserView = new BrowserView(browser);
        pane.getChildren().add(browserView);

        AnchorPane.setTopAnchor(browserView, 0.0);
        AnchorPane.setBottomAnchor(browserView, 0.0);
        AnchorPane.setLeftAnchor(browserView, 0.0);
        AnchorPane.setRightAnchor(browserView, 0.0);

        final String url = "file://" + pagePath;
        browser.loadURL(url);

    }
}
