Windows 7, Cassini and Firefox run slow as molasses together…..

I have been developing on Windows 7 64-bit for a couple of weeks now and really like the Windows 7, but wow have my web applications run slow. I figured I would debug the issue later as maybe it was my data layer running slow. Each time I would execute a page refresh, load, navigate, whatever, it would take 2 seconds. Doesn’t seem like much, but when you click a button on a page 2 seconds is a very long time to watch it hang.

So, after getting sufficiently annoyed and impatient I was able to find that it was my app but was Firefox. Apparently Firefox has some sort of issue with IPv6.

The fix is amazingly simple.

  • In the address bar type ‘about:config’
  • Filter by ‘v6’
  • Disable ipv6 support.

Thanks to Peter Gregory for the help.
