How to get better performance when creating WCF clients using ChannelFactory<T>

NinjectWebCommon.cs

private static void RegisterServices(IKernel kernel)
{
    // The ProxyGenerator is part of Castle and will emit code at runtime.  This code needs to be cached
    // or there will be zero improvement in performance.  It's cached by default, per instance of the 
    // ProxyGenerator.
    kernel.Bind<ProxyGenerator>()
        .ToConstant(new ProxyGenerator());
    
    // The ChannelFactoryCache will cache the creation of the ChannelFactory, which is slow because it 
    // requires the use of reflection.
    ChannelFactoryCache.Add<IWebServiceInterface>(endpoint, GetBinding(endpoint), null);
    
    // Setup Ninject to provide instances of a dynamically generated class which will create instances of 
    // a WCF channel on the fly.  See the ToWcfClient extension method.
    kernel.Bind<IWebServiceInterface>()
        .ToWcfClient();
}
