Google Chrome is slow to localhost

Question

For some reason Google Chrome is slow when I'm working against localhost. I had the same problem in Firefox 3.5 but I changed some IPv6 setting in about:config which fixed the issue. I think the same problem occurs in Google Chrome, but I can't find out how to fix it.

Any ideas?

Solution

Just an idea : do you have a line that looks like this :

::1 localhost

in your hosts (it should be somewhere like C:\WINDOWS\system32\drivers\etc\hosts, if I remember correctly) file ?

If yes, comment that line by adding a # at the beginning.

This way, the only line that's about localhost should be

127.0.0.1    localhost

which is IPv4.

It might help, if your problem is really caused by IPv6.

You're welcome :-) Was just a wild guess, but nice to seen it worked ! (might be useful one day on another, actually ! )

@blahblah - You should mark Pascal's answer as "accepted". @Pascal - thanks so much for this fix, this was really slowing me down as I was testing sites locally in Chrome.

This makes a huge difference. Both lines were commented out for me in Windows 7, so I uncommented the IPv4 line and everything works great now.

I've been using this fix up until Chrome 8, but now that Chrome 9 has been released, it seems to be slow again. Has anyone found a fix for the current version?

Can someone explain why does this work?

Doesn't solve the issue for me.

Doesn't work for me (Win7 x64). As soon as wi-fi is on, accessing localhost is slow, when I disable wi-fi then it's fast. Tested in IE, FF and Chrome. NB I do not use any web filtering.

After trying loads of different things, @RustyX gave me the best answer. If I turn off the Wi-Fi and just use the ethernet connection, it works sooo fast. Thanks dude.
