  • Resume from hibernation longer than cold boot?

    If it shut down the computer, and do a fresh start up, it takes about 30-35 seconds consistantly. Now if i resume from hibernation, it takes well over a minute. what gives?

        If you have lots of ram and a slow drive, resume is going to be slow. Windows doesn't compress the hibernate image either, so you will be bottlenecked by the transfer speed of your hdd. 20gigs sounds pretty old. I'm betting it's probably 5400rpms too.

          If your running xp drop to 1GB of ram (could even do 512 since you'll never use it)....unless you plan on doing any high quality fps games while driving....

            While on the same topic. Will windows straight copy a 2gig image to the disk from RAM and back, or does it only copy what's used? I know in Linux, if I have 2gigs of RAM and i'm only use 300mb, it'll only copy 300 megs and it'll compress it as well using all available cpu cores.

              The drive is 7200 rpm

              I was always under the assumption that more ram was better. I was thinking about getting a smaller cf card and loading xp to that. Would that be any better? I dont really mind a fresh boot, more just a curiousity question.

                @tom04841:
                More ram is better was a tactic that was used for years to boost hardware sales.....its really only true in very memory intensive tasks like photo/video editing.

                @kev000:
                Windows only moves used pages to the pagefile but since the pages can be scattered throughout the memory map it usually is a lot more data moved then actually used. I should also add that hibernation files since xp have been compressed but the full size of the physical ram is allocated when hibernation is enabled to prevent fragmentation. Most of the file is empty if you flip through it.

                  That's curious. I have 2 gig of ram too, a 5400 rpm 160gig scorpio blu, xp sp3, it takes 12s to hibernate, 8 to resume, and 25s @ cold boot. I have xp prefetcher disabled, so it doesn't preload ram with tons of stuff "I could use".

                  Of course some services are disabled, too
