在Chrome+Visual Studio中調試asp.net程式很慢的問題（Firefox也有類似問題）

今天開始起在Chrome中調試，發現問題主要出在菜單欄（layout檔案）中，google了一番，查到很多原因，不過最終解決方法倒是很簡單，特此分享一下：

在C:/Windows/System32/drivers/etc裡邊有一個hosts檔案，用記事本打開，裡邊最後幾行原來是：

# localhost name resolution is handled within DNS itself.

# 127.0.0.1       localhost

# ::1             localhost

删掉127前面的#，改成：

 127.0.0.1       localhost

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)

127.0.0.1       localhost

# ::1             localhost

2. Firefox-only solution:​

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.

​

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
