Currently I'm facing a very strange Behaviour. I know, that Internet Explorer might be slightly slower than it's competitors, but i used to use it for various reasons.
However at the moment it is impossible:
IE is taking VERY long to resolve a hostname. About 30 seconds PER hostname. Loading Facebook with all the foreign servers involved takes about 3 Minutes to finish.
Chrome and Firefox are working as expected - split second.
The strange thing is: The IE Issue does NOT apply for all websites. Some are loading as expected. Pages where i noted this very slow behaviour are:
- google (starting with the main search page, Search-as-you-type is a nightmare)
- youtube
- various MS-Sites like technet, msdna etc.
Strange behaviour continues. This Issues does apply for:
- IE 11 on Windows 8
- IE 11 on Windows Server 2012
- IE 11 on Windows 7
- DOES NOT APPLY: IE 11 on a Windows 7 Notebook (same Version as the Desktop uses)
it's about the very same set of sites...
Things I tried:
- Disable Proxy-Auto-Configuration
- Reset IE.
- Use Google DNS directly.
- Restart DNS-Server, Router
- Fullscan for Maleware
- Run IE without Addons (Save-Mode)
- Reinstall IE (add/remove from windows features)
It seems related to the latest Version of Internet Explorer. However, I cannot find something on the internet, neither does it apply for all websites.
At the moment i'm absolutely out of ideas where to start..
ps.: I have my own local DNS server(s), so i first thought, that Chrome and FF might use other DNS servers directly and thats the cause - but even if i completely disable my own DNS Servers, reset the cache and provide the google-dns directly, the issue is present.
I'm pretty sure it's just about the DNS-Resolving. Once a certain hostname responds, downloads are fast as it should be. (but up to 45 seconds to start)
I noted, that Outlook has some troubles connecting to my exchange servers as well... So, it seems like there is some setting -which MS-Products are using - that are slowing progress down...
