The problem:

• If i access SharePoint from Windows 7 with IE8 or Chrome5 - I must wait for like a minute to get a response. If i use other Windows 7 with IE8, just the same - just wait a MINUTE.
• If i use Firefox3.6 on W7 machine - page opens up instantly.
• Now switch to IE rendering engine in Firefox, you will have to wait just as with IE.
• Now i tried IE8 on XP SP3 - page opens up instantly.
• I tried IE8 on Windows Server 2003 SP2 (machine on which SharePoint is hosted) - page opens up instantly.

The question

Similar question has been asked but there is no response and i`m trying to access page without SSL and that happens even on GET requests.

Where do I look? Where would be the problem? Browser? OS? I don't even know what to think about.

Just a note

Just a note about chrome's process isolation: I found it sad that while I was waiting that minute with Chrome, i could not use any other tab (i could switch, but i could not, for example, scroll or use any controls)
