Very slow loading time with Visual Studio and ASP.NET MVC?

Question

hi,

I'm developing an ASP.NET MVC website with Visual Studio 2010. The site is built and running from the local computer with the local built-in ASP.NET Development Server, the database is located somwhere on the net.

The problem is that it is very slow to load or reload the page, take a look on this sceen :

Any idea why this is that slow?

BestRegards

Edit : I have found out that this do only happen i Firefox, IE will return the page ALOT faster?

Answer 1

Quick Fix

Just change

http://localhost:XXXX/YourSite/Here

To

http://127.0.0.1:XXXX/YourSite/Here

Much better IMO than disabling IPv6 settings in Firefox, what if you want to use IPv6?

More Permanent Solution

If you want a slightly more permanant solution, you can edit your hosts file, normally C:\Windows\system32\drivers\etc\hosts on Windows, and add a rule for localhost:

127.0.0.1 localhost

Customising Firefox Specifically

If you do decide you want to disable IPv6 in Firefox itself, there are details of that here: http://kb.mozillazine.org/Network.dns.disableIPv6

Edit: Actually, if you want to fix this in Firefox, rather than disabling IPv6 entirely as in the link I just posted, or as specified by the other answer to this question, give this a read: http://theycallmemrjames.blogspot.com/2010/09/firefox-is-really-slow-testing-sites-on.html This shows how to set a rule for localhost to only use IPv4, so your browser may still use IPv6 as it needs.

If you run into the same issue, disable IPv6 support in Firefox: about:config -> network.dns.disableIPv6 -> true Apparently Firefox and Microsoft Internet Information Server do not like to play together nicely on Vista without human intervention.
