    Two identical machines, 10 second boot time difference


    I have two identical MSI GT80 SLI machines, configured identically hardware wise and software wise also. Well, there is one difference, one has lower bandwidth RAM than the other. 17000 vs 19200. Both have 32GB. Latest-greatest 10 obviously. Samsung 970 EVO PLUS 2TB is the boot disk on both. One disk was a clone of the other via Macrium. About a month ago, and since then I did configure them a bit different from each other. Install this software package or that. BIOS looks identical. powercfg is identical. startup is almost identical, in fast the fast machine has more things starting than the slower one. I did go into startup and uncheck everything thought I thought could slow it down. To no avail. The 10 second slower boot time just will not go away. The 'fast' machine gets to the login screen in 21 seconds, the 'slow' one in 31-35 seconds. Is there any easy way to tell what could cause that discrepancy. Just wondering where 10-15 seconds seconds goes every time.

    :)

    The "boot time" that windows references is simply the time it takes for the motherboard bios to hand things over to windows. As such they call it "last BIOS time".

    What you could do is dig around in the bios and remove some Boot options within it, remove the ones that you would or could never use but if you plan to boot via usb for example at some time in the future, leave that one somewhere in the list. Example for MSI.

    Two identical machines, 10 second boot time difference

    Hi dictum,

    Both those start times are quite reasonable, however; I understand your interest in knowing exactly why they are different. This boils down to how much time are you willing to invest to potentially save 10-14 seconds. *Smile

    Have you compared time to boot to Safe Mode on both PCs?



    This link to a vbs script will provide a more exact boot time for comparison of regular boot times.

    Restart time vbs from Seven Forums



    This post references the use of Microsoft AutoRuns and Windows Performance Analyzer to help understand startup delays.

    How to optimize windows10 - XP still seems faster



    I would suggest starting with AutoRuns first. If you watch the video, it will direct you where to look to identify startup delays. Also, you should be able to compare both PCs configurations a bit more precisely.

    Then finally, Windows Performance Analyzer will show the entire details of the boot process in a graph format. This will clearly identify what portion of the boot process is different between the two PCs.

    One caveat with WPA, the volume of data produced can be a bit overwhelming. Analyzing the results in order to effect positive results can prove challenging. *Smile
