Give the system a day or two. On a new installation, Vista does extra
monitoring and maintenance during boot. After these are out of the way,
usually 2-4 boots, then it will start to get faster, as the prefetch
technologies will be monitoring your boot time and adjust the system for the
best performance possible.
For example, on one Laptop I have, the first boot time was like 3-4min, as
it was timing out because of a driver. On the next boot, the time as 2-3min
as Vista no longer tried the bad driver access method it used on the first
boot.
So give it a chance to figure out the fastest order to load drivers, and
initialize the system, as well as get the initial reporting and maintenance
steps out of the way.
This is just like the HD activity on a new Vista installation after the
machine is booted. The HD activity and even the performance during this
phase is a bit annoying as Vista goes through your entire system and indexes
files and folder and creates thumbnail caches and then defrags the
installation on the HD for the best performance. (Each on their own isn't a
problem, but at first when all this is happening at once for the entire
system, it makes the HD light quite bright.)
I recommend that Users let Vista run through the night getting all this
stuff out of the way, and then you can feel how snappy and fast Vista really
is, since you can't base the performance on the initial installation feel.
Also the caching system in Vista keeps getting smarter and smarter, and
after a day or so of use, you will find the programs you use will seem to
fly open, as Vista monitors your work patterns and pre-loads HD information
into the cache based on how the program loads, but also on how you work and
the order you normally use and access programs and tools on the computer.
Trust me, you will be shocked when you go to open a slow loading program
like CorelDraw and it opens in a second, or even Word just seems to pop open
like it was already running, when it wasn't.
BTW The boot time after a few days seems to be about 5 secs longer than XP
based on our testing installations. There are a few systems where it is also
faster, but it averages out to be a few seconds slower for the full boot.
(Considering how much more Vista is doing over XP, this is something that is
worth the few seconds.)
Also if you are like me, I use sleep and Hibernate for everything, and these
work quite well in Vista, so rebooting for an update or driver is less than
once a month at the most on average for myself.
Good Luck,
