winform load slowly

[bray09]

Can anyone tell us what the LOAD (URL) has been doing for such a long time (Bold Font)? how to optimize the loading speed.
Environment: win7 x86 net4.6.1 CefSharp.WinForms -Version 104.4.240

 `browser = new ChromiumWebBrowser();
        //注册JS对象
        browser.JavascriptObjectRepository.Settings.LegacyBindingEnabled = true;
        browser.KeyboardHandler = new CEFKeyBoardHander() { CanReload = WebAppContext.IsReload, CanShowDevTools = WebAppContext.IsShowDevTools };
        browser.DownloadHandler = new DownloadHandler();
        browser.MenuHandler = new ContextMenuHandler();
        browser.TitleChanged += OnBrowserTitleChanged;
        browser.LoadError += OnBrowserLoadError;
        browser.FrameLoadStart += Browser_FrameLoadStart;
        browser.FrameLoadEnd += Browser_FrameLoadEnd;
        browser.LoadingStateChanged += Browser_LoadingStateChanged;
        browser.IsBrowserInitializedChanged += Browser_IsBrowserInitializedChanged;
       browser.Dock = DockStyle.Fill;
        this.pnlWeb.Dock = DockStyle.Fill;
        this.pnlWeb.Visible = true;
        this.pnlWeb.Controls.Add(browser);
        browser.Load(WebAppContext.WebAppUrl)`

this is the debug.log:

How does it behave if you disable proxy resolution?

settings.CefCommandLineArgs.Add("no-proxy-server");

More detailed example included in https://github.com/cefsharp/CefSharp/wiki/General-Usage#cefsettings-and-browsersettings

Environment: win7 x86 net4.6.1

How does a Win 10 machine perform?
