How to Optimize Vista

[Phopojijo]

Is there any particular reason why with all running applications combined never seem to use more than about 50% of my ram, even when doing a memory intensive process such as rendering but the task manager clearly shows that 90 to 95 % of my ram is being used, and 100% of my physical ram is being used? Its as if some hidden process is using up the other 50% of my physical ram.

Because Windows always used all available RAM regardless of how much was used by programs in general.

It prefetches what it assumes you'll eventually be using so you don't need to access it from the hard drive. Why not? When it needs the RAM it will kick the extraneous off, if it doesn't need the RAM it'll potentially speed up later if it just so happened to prefetch something that ended up being used. As an example, if you use Firefox daily... it might dump firefox into your RAM if it has extra space -- assuming at SOME point you'll turn firefox on and it won't need to even look at the harddrive.

Only thing I disagree with is the scheduled defrags. I set mine to once a week on Saturday morning at 2:00am, and I haven't had any problems.

He'd disagree, as would my first 2 times attempting to install Maya and a few Battlefield2 games in Beta2. It doesn't always hurt, but when it does, its a frick'n cyclone.
