7 seconds to open a folder?! Definitely something wrong. My Win7 machine opens folders instantly, just like it did on XP.
Is this quite low-spec hardware that's been upgraded to 7? A lack of RAM in particular will make 7 feel slow compared to XP. A system with 0.5-1GB will do basic stuff pretty well under XP but will be a dog under 7. Once you get more than about 1.5GB in there, 7 will be at least as quick.
No , its on several dual boot systems (with Xp32 and win7 64 bit)
specs: q6600 @ 2.4G with 4Gig ram
dual core 1.86 @ 1.86 with 4Gig ram
i7 920 @ 3.6Gig with 6Gig ram
Same hardware and same network but totally different results between both OS
