Vista Superfetch

[abcdefg]

if my or any Games/Apps had 100% compatibility with Linux, I wouldn't hesitate and would switch completely in a heartbeat. :p

But there you have that magic word if.

Take my word:

Microsoft won't make great OS unless it's forced to do so and I don't see that happening anytime soon.

for me vista vista runs good and my system is just a over a year old,mind you 2GB is the sweet spot for vista.

Xtreme2damax:sounds like you do have some problems with vista,if xp worked for you then stick to what works,if vista has what you want then try it but if anything comes up that needs fixing you need to try to fix it or better yet test it,i'm still testing vista and it's getting better,if you go in without testing you will get burned.

Superfetch is good if you have 2 or more gigs of mem.

Superfetch is good if you have 2 or more gigs of mem.

Superfetch is good with 1 GB of RAM or more. Anything less and it becomes a hindrance.

[Jeff-Flowers]

Superfetch learns which applications and data should be kept in memory, superfetch assigns a priority to memory's pages.

Does SuperFetch keep separate profiles for different users on a machine?

Xtreme2damax, so you wanna explain to me why my system still runs fast and load everything fast EVEN when my settings are in power saver WHICH UNDER CLOCKS my CPU to 800MHz. My spec are as follows:

Laptop

C2D T7300 2GHz

2GB RAM

Intel X3100 graphics card (3.5 WEI)

200GB HDD

OR Anyone wanna explain WHY MY SYSTEM LOADS APPS FAST and browsing the internet with NO LAG before you guys talk more **** about vista.

Give me your system and i will show you how slow is....

Browsing Internet? I can browse Internet with no lags on Pentium III 1Ghz

[ntbnnt]

i never experienced any sort of hang, but then again i keep a nice clean startup

did you read what I said or you are just posting what YOU thought I said.

i really have no idea what this test is supposed to prove. the whole point of Superfetch is to quietly pre-load applications/files that you most frequently use. that you're 'testing' it by loading 40+ programs right after you boot will obviously overload Superfetch, and goes beyond what any normal user will even attempt. you're gaming it to be a drain, and succeeding at it quite nicely.

in any normal setting Superfetch is a net positive for Vista.

Core 2 duo, 2 gig ddr2 with no games installed on XP or Vista.

Xp boots into desktop and then some slight hd activity for a sec or two.

Vista Ultimate boots into desktop in about the same time as XP yet after a few secs there is heavy hd activity for around 40 secs with Superfetch loading.

Some apps that I try to load within this heavy hd activity are sluggish compared to after.

XP is far snappier than Vista in all aspects here and they are installed on their own identical drives which are plugged/unplugged as needed.

Does it bother me - no, not really as I like both XP and Vista.

superfetch uses low priority I/O queuing that is a new feature in windows vista. it will use idle hdd bandwidth to load things into ram

superfetch does not try to immediately load two gigs of apps into ram all at the same time, it's low priority cpu usage, and low priority i/o.

and yes superfetch keeps separate profiles for the different users

my personal experience has been that any app i commonly use loads nearly instantaneous, similar to if it was just minimized.

it is not aggressive, i have no idea where people got this idea from,

here's an article about it straight from m$

http://www.microsoft.com/technet/technetma...el/default.aspx

Whenever memory becomes free-for example, when an application exits or releases memory-SuperFetch asks the Memory Manager to fetch data and code that was recently evicted. This is done at a rate of a few pages per second with Very Low priority I/Os so that the preloading does not impact the user or other active applications.

okay so this means, if YOU are using your computers resources for ANYTHING at all, superfetch takes a back seat using no HDD bandwidth at all

edit #2 in response to an earlier post: In fact, vista will load a game into ram if you play it enough, it doesn't care what is being cached, it will do everything. (yes even oblivion) this is most likely to increase your boot times of the game, the loading times will see a lesser performance boost, as superfetch does not cache stuff into your vram yet!!!!!!! BUT vista is working on it :D

This is my experience as well. Although my harddrive may work a bit after startup, I seem to be able to carry on working without any noticeable performance hit. This often makes me wonder if people who complain about Vista disk thrashing are just sitting back and waiting because they see the harddrive light on their PC flashing.
