今天開始起在Chrome中調試，發現問題主要出在菜單欄（layout文件）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裏邊有一個hosts文件，用記事本打開，裏邊最後幾行原來是：
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
刪掉127前面的#，改成：
# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
# ::1 localhost
立竿見影。

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