How to improve performance in Skin Storage while using VisualStyles in WPF?

<syncfusion:ChromelessWindow x:Class="Sample.MainWindow"  x:Name="window"                           xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml xmlns:sfSample="clr-namespace:Sample"                             xmlns:syncfusion="http://schemas.syncfusion.com/wpf Title="MainWindow"                               syncfusion:SkinStorage.EnableOptimization="True"
syncfusion:SkinStorage.VisualStyle="Office2010Blue" >

Syntax: 
SkinStorage.SetEnableOptimization(DependencyObject object,bool value)
SkinStorage.SetVisualStyle(DependencyObject object,string value)
Example: 
SkinStorage.SetEnableOptimization(window, true);
SkinStorage.SetVisualStyle(DependencyObject object, “Office2010Blue”);
