在Chrome+Visual Studio中调试asp.net程序很慢的问题（Firefox也有类似问题）

今天开始起在Chrome中调试，发现问题主要出在菜单栏（layout文件）中，google了一番，查到很多原因，不过最终解决方法倒是很简单，特此分享一下：

在C:/Windows/System32/drivers/etc里边有一个hosts文件，用记事本打开，里边最后几行原来是：

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

删掉127前面的#，改成：

# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
# ::1 localhost

立竿见影。

While developing an ASP.NET website running it on the Visual Studio ASP.NET development server I was noticing that page loads exceedingly slowly in Firefox and Google Chrome after upgrading to Windows 7 (same issue occurs with Windows Vista).

A page refresh would usually take up to 3 seconds (localhost) even without changing the source code (so it should be instantaneously, especially now that I’m using a SSD).

It appears that there is some kind of bug on Vista/Windows 7 with DSN and IPv6, but that can be easily fixed. Here are some of the solutions I have found:

1. Recommended Solution – machine wide: uncomment the localhost address in the hosts file (%WINDIR%/System32/drivers/etc/hosts): (source)

2. Firefox-only solution: disable IPv6

3. System wide-configuration (option 1):Disable IPv6 Random identifier

4.System wide-configuration (option 2): Disable IPv6 from Your LAN Interfaces and Connections
