Question

在asp.net网站上，仅在几个工作站上我在IE8上遇到以下问题：

通过使用该网站，IE的内存消耗量增长并超过100兆字节，从超过90兆字节的那一刻起，浏览网站变得极其缓慢或不可能。

不幸的是，此行为仅在某些PC上重现。其他人正确释放内存，IE永远不会超过50兆字节。

所有经过测试的系统都是带有IE 8 8.0.6001.18702的Windows XP SP3，但具有不同的硬件（从Core 2 duo / 2Gb到Core i5 / 4Gb）。我甚至能够在Microsoft（App compat）提供的（Win7 / IE9 9.0.8112.16421）虚拟机中重现它。

我认为问题出在客户端，但为了确保问题不是来自我的网站，我决定建立一个简单的网站（基于VS2010 ASP.net Web应用程序模板）来重现问题：

Default.aspx：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Test._Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <asp:LinkButton ID="LinkButtonHome" runat="server" onclick="LinkButtonHome_Click">Home</asp:LinkButton>
    </div>
    </form>
    <script type="text/javascript">

        function clickHome() {
                    document.getElementById("<%=LinkButtonHome.ClientID %>").click();
                }


    </script>
</body>
</html>

Default.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Test
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void LinkButtonHome_Click(object sender, EventArgs e)
        {
            Response.Redirect("Default.aspx");
        }
    }
}

我以为我必须从我的网站添加组件，但我设法用这个简单的网站在同一台计算机上重现问题。

我确定我错过了一些东西，但IE是唯一可以在我的情况下使用的浏览器，我不知道在哪里看，

你有什么想法吗？

先谢谢。

Answer 1

正如您所描述的那样，错误是每次页面加载时发生的内存泄漏。从javascript使用中泄露的可能性很小，因为即使使用最小页面也是如此，所以我想的下一个就是IE插件。

所以我认为你的其中一个内存泄漏了。

我建议找到并禁用所有未使用的IE扩展程序。

打开IE，然后从“菜单工具”中打开“管理加载项”并逐个单击并禁用所有不需要的加载项。甚至可能只是为了看看这是否是问题。

备选方案，您可以下载autoruns from sysinternals并查看也可以禁用它们的IE插件。
