在asp.net javascript中优化表单提交速度

Question

我目前正在开发一个asp.net应用程序并尝试发布一个表单数据，而我使用以下代码在表单提交时延迟：

 window.document.frmlogin.action = "LoginCheck.aspx"
            window.document.frmlogin.method = "post"
            window.document.frmlogin.submit()

我的webconfig文件如下：

<appSettings/>
<connectionStrings/>
<system.web>

    <compilation  debug="true" >

    </compilation>
<!--
  The <authentication> section enables configuration 
  of the security authentication mode used by 
  ASP.NET to identify an incoming user. 
-->
<authentication mode="Windows" />
<!--
   The <customErrors> section enables configuration 
   of what to do if/when an unhandled error occurs 
   during the execution of a request. Specifically, 
   it enables developers to configure html error pages 
   to be displayed in place of a error stack trace.

   <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
     <error statusCode="403" redirect="NoAccess.htm" />
     <error statusCode="404" redirect="FileNotFound.htm" />
   </customErrors>
-->
</system.web>

如何优化上述代码以提交更快的表单提交
