    An SSD will make a big difference in booting. I think this thread has shown that. I don't know any game that requires more than 2 gigs that will run decently on a Geforce 9300.

    Exactly....my point was cut back on the ram its not helping at all-its only hurting.

    An SSD will make a huge performance difference, but honestly feeding a system like that would require a few of them in a high performance raid array....lucky you don't need to do that because you won't be using the system for anything even close to what your building it for.

    All good points. Another possible alternative might be to move to a dual battery setup. Keep the CarPC (and in turn all downstream devices connected to it) hooked to the second battery and use an isolator switch so that the alternator can charge both batteries when running. And even if the auxilary battery goes completely dead, your car will still start. Typical automotive batteries have a 70AH discharge rate.

    i.e. it can discharge 70A for 1 hour

    or

    1A for 70 hours.

    We are talking mA here, even if S3 draws 200mA, the auxillary battery should be good for atleast 350 hrs, or give or take 10-12 days.

    p.s. That's assuming you want all those 30 USB devices and the 8GB of RAM. 30 USB devices??? What are ya running dude??

    I'm sure using an SSD doesn't reduce my resume from hibernate time by much. Probably because the resume side of things is only 6 seconds (+7.5 seconds POST). I'll stick another drive in later & time it.

    @justchat_1 - I didn't mean cold-boot, I meant resume from hibernation - the key thing was the PC went through POST I've read before that those Jetway boards can POST real fast and 3 seconds resume is excellent - could you supply details of OS/RAM/Frontend/attached devices, etc.

    Thanks

    Meh, i know i can get Linux to boot faster than I have. The issue I take with going much further is that I'd have to make my Linux less generic and more specific to my hardware. I want to keep linuxice as hardware agnostic as possible so more people can use it. I may do my own kernel just to show the difference it can make.

    I'm nearing the point anyway where I have actual cpu and memory bottlenecks and not just hdd bottlenecks. Cold boot is a lot more cpu intensive than a resume is.

    As pictured in the video was my dev laptop:
    Win7 embedded stripped clean, 2Gb of ram, 500GB 7200rpm hard drive and a core 2 duo.
    my carPC:
    win7 ultimate stripped clean, 1GB of ram, 30GB SSD and a core 2 duo.

    But truthfully the biggest thing deciding resume speed is hard drive performance and os optimization. Cpu doesn't do much and memory bandwidth is far more then even a raid array could spit out.

    I'm confused, I thought you said you had a Jetway mb connected to a M4-ATX! Are you saying your DELL laptop has a Jetway mb?

    Do you mind listing what services you turned off or adjustments you made to 7embedded?
