I've tested Chrome under Windows 7 x32 and x64 and virtual XP x32 on Windows 7 x64. It looks like Chrome + Windows 7 x64 is about 500ms slower than on other systems. Other browser like Firefox, Opera, Internet Explorer are on Windows 7 x64 faster.
It can be easily checked with browsers' default Developer tools, just check network response. Chrome + Windows 7 is always 500ms slower...
My question is simply why?
Is there something wrong with my configuration? Where and what?
I've checked some internet hints like to change LAN option - useless.
I've just tested switching off AntiVirus and Firewall - no difference.
