Question

IE8 on Localhost really slow - Firefox, Opera, Chrome and Safari all fast on the same - why?

Answer 1

A:

Under Tools -> Internet Options -> Connections -> LAN Settings, is the box "Automatically detect proxy servers" checked?

If so, that does a DNS request to wpad.(domain search suffix) to discover proxy servers via their Auto Discovery Protocol.

If nothing responds, the query will have to timeout before it gives up.

Thank you for the suggestion; this setting was NOT ticked. But it works instantly when I use 127.0.0.1, so it seems to be a problem with IE8 attempting to resolve 'localhost'.

Answer 2

A:

I have exactly the same problem as you do, except I'm using IE7 (IE takes about 16 seconds to load localhost, while Firefox and Google Chrome loads it in an instant).

I don't have the autodiscovery for proxy checked either. I also tried starting IE without add-ons (From Accessories->System Tools) and it didn't make a difference.

I found out that using 127.0.0.1 instead of localhost greatly improved the speed (like 2 seconds instead of 16 seconds!). However, I edited hosts file and I left only the line

127.0.0.1 localhost

and this didn't fix the problem. Need to dig some further.

Answer 3

+2 A:

Try the following:

1- Navigate to C:\Windows\System32\drivers\etc

2- Open the file hosts using any text editor

3- Add this line to the end of the file

127.0.0.1     localhost

4- Before you save this file, you need to make sure that any program that access the internet (browsers etc.) is closed - Save the file and test it

Answer 4

A:

I also had this exact same problem recently - 'localhost' taking 15 seconds to load, but 127.0.0.1 loading instantly.

However, I have now fully solved my problem, so I write here in the hope that it will help someone.

My problem coincided with the purchase of a D-Link DIR-655 wireless router, so after trying many of the kindly offered 'fixes' on this forum, I turned back to my router settings in search of an answer.

I eventually discovered a setting on the SETUP - NETWORK SETTINGS page. The 'Enable DNS Relay' box was checked, so I read about it, and it apparently allows the router to lookup DNS addresses from the ISP's server. This is obviously not desired for a 'local' address on my own PC, and so I tried unticking it.... and HEY PRESTO, IT WORKED!!!

I hope this work for some of you, too!

All the best,

Rob
