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][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][])

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

**2.** Firefox-only solution: [disable IPv6][]

> 1. Type about:config in the address bar and press Enter.
> 
> 2. Scroll down until you find network.dns.disableIPv6.
> 
> 3. Double-click on it to change its value to true.
> 
> 4. Restart Firefox.

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

> netsh interface tcp set global autotuninglevel=disabled

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

> 1. Launch Vista, click on Start, and then click on Run. Once the Run window appears, type regedit.
> 
> 2. Once you have accessed the registry, you will add a registry value as follows: (DWORD type) Set to OxFF.
> 
> 3. The registry is as follows: HKEY\_LOCAL\_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip6/Parameters/DisabledComponents
