  • hibernation and resume slower than shutdown/startup

    going into hibernate and resuming from hibernate goes slower than just shutting my system down completely and restarting it. i have nlite'd my xp down to a 248mb image.

    Size of the install doesn't matter. How much ram? You may want to limit to 512 or something and see how much of an improvement you get. Hibernation speed is dependent on a couple of things. System speed, HDD speed, and ram size. Smaller amount of ram will definitely improve it though.

      its at the max the computer will allow, 1 Gig. a smaller amount of ram makes for a quicker resume? wow, i woulda thought the complete opposite.

        Hibernate just takes every byte in ram and makes a copy onto disk. So the more ram you have, the more data it has to write to disk and then read from disk. It writes/reads every byte of memory, not just memory in use. That's why amount of ram and HD speed are the 2 main components in hibernate speed.

          Yup klundy hit it. If you check your hiberfil.sys or wtf ever it's called in the root of your windows drive, you'll see it's the same size as your ram. There's also a way to limit windows to a smaller amount of ram so you don't have to pull ram out. You can experiment with different sizes by adding the /MAXMEM= option to your boot.ini file. I'd say Try 768, 640, 512, 480, 384 and see how it goes. Check how the system runs and how fast hibernation works, and find a good harmony between the two.

            hmm, i never knew that hibernate worked like that.

            could you give me the windows tweaking for summies guide to doing this?

              Sure can.

              boot.ini should be in the root of your windows drive, typically C: drive.

              Open that up, just double click, and then edit away.

              You should see a couple lines like this:
              Code:
              [boot loader]
              timeout=30
              default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
              [operating systems]
              multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
              Change it by adding /MAXMEM=whatever you want it to be to the very last line like this:
              Code:
              [boot loader]
              timeout=30
              default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
              [operating systems]
              multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /MAXMEM=512

                  You have to go to my computer>c: drive>tools>folder options>view and select view hidden system files and folders to see those files.

                    Oh yeah, forgot that step...

                    Or you could just open it directly (I think...) by opening up notepad, then file, open, and just type in c:\boot.ini and edit away.

                        Will the maxmem option only work for hibernation or will it limit the amount of memory Windows is using.(same as taking memory out)

                          ^I am wondering the same thing. If you have 512 ram and set maxmem to 256, what happens to the rest of the memory?

                            Windows doesn't use it. It limits the usable amount of memory available to windows to whatever the MAXMEM value is set to.

                              Basically in my carPC system I use 1Gb of ultra fast ram.

                              I had an old 40Gb fujitsu IDE hard drive I was using with a custom stripped out version of XP.

                              I have now upgraded the hard drive to a western digital 320Gb SATA hard drive that is faster but I am using a full version of XP.

                              The hibernation and resume times have increased tho??
