#70
What you are realizing now is that 7 just isn't seeing more services but new features. You also have to look at what you have installed on both there too. IF you have a different software environment by seeing more loaded onto 7 then Vista that will have a direct effect.
Here I will be making comparisons with both RCs each on their own set up as stand alone installations as well as Vista HP 32 on a third drive seeing more installed on both 7s then Vista while Vista still appears slower. The delay seen here when shutting Vista down is due primarily to one item left to identify taking longer to close out there.
7 overall in the long run will be a bit faster while any version of Windows can start seeing slow down after a lengthy period of time from various programs being installed and later removed leaving items behind in the registry. You also start seeing a large collection of temp install and unstall folders at some point requiring the slight increase in access time when going to browse through various folders on the drive.
The primary item that will make the most difference is the refinement of the kernel over Vista there. Once you pile a ton of items on top then things tend to see the typical slowdown. With Vista that was things like the new Aero themes, side bar, and gadgets that saw the most blame there.
