erm...lol
The tests, run on a Dell XPS M1710 test bed with a 2GHz Core 2 Duo CPU and 1GB of RAM
well, that part i bolded explains exactly WHY it ran slower for them.
whenever anybody has problems with something i know about, i first look at there specs.
something i have noticed among vista users/triers is that:
nearly all of the people who complain about it being slow or have other trouble have less then 2gb of ram.
nearly all of the people who have no trouble with it have more then 2gb of ram.
so...its pretty obvious to me that ram is the main issue with people not being able to run vista nicely.
vista uses more ram then xp. so of course it will run noticeably slower then xp on a computer with only 1 gb of ram. thats why its easily possible to upgrade computers. besides that, EVERY OS ran slower then the previous one when put on hardware made for the previous one.
ie, vista runs slower then xp on the hardware that was made for xp
xp ran slower then 98 on hardware that was made for 98
98 ran slower then 95 on hardware that was made for 95
95 ran slower on hardware that was made for 3.1
each os released needs more ram and hard drive space then the previous OS and thus ran slower on hardware that was fine for the previous os.
