  1. Slow boot, performance degradartions, and need help about WPAWindows Performance Analyzer


    Hello.
    I need help about issues above, i had to describe it completely for better guidance. Sorry if it takes long to read but needed help.


    I've been having performance issues since i installed windows 10.

    Slow boot, bad performance mostly, sometimesinfinite black screen boot.


    Anyway, even though i had a new installation of windows 10Like 2-3 months or so i had a bad boot loading and acting.

    I mean sometimes fast boot just would fail and would result in an infinite boot time, plus, boot w\o using fast-bootLike when loading AFTER restarts would take a HELLUVA LOT time.
    So i decided to do some searches. I've used Windows event viewer and there were lots of 101 errors.

    I mean errors like "This application took longer than usual to start up, resulting in a performance degradation in the system startup process"
    Process are vary. each startup has 2-3 errors like this, and sometimes itsexplorer.exe, sometimes it's mmc.exe and etc, etc.


    Any ideas? I used WPA and WPR too, recording boot traces for 3 times but i don't really know how to read their graphs.

    Thank you for reading, and thanks for helping in advance.

    :)

    Win10 Slow boot time. Help debug with Windows Performance Analyzer

    Hi,

    I think that the issue is caused by the "Generic HDD SCSI Disk Device" driver


    Slow boot, performance degradartions, and need help about WPAWindows Performance Analyzer [​IMG]


    you have 8 disk drive attached to your computer:
    1. Samsung SSD 860 EVO 500GB
    2. Samsung SSD 850 EVO 250GB
    3. ST4000DM004-2CV104
    4. TOSHIBA DT01ACA200
    5. WDC WD20EARX-008FB0
    6. Generic HDD SCSI Disk Device
    7. Seagate BUP BK SCSI Disk Device
    8. Kingston DT Elite G2 USB Device

    I would suggest you uninstall the Generic driver from the device manager;
    • Open device manager and display the hidden devices;
    • Generic "HDD SCSI Disk Device" under disk driver and uninstall it.

    Win10 Slow boot time. Help debug with Windows Performance Analyzer

    My win10 has a long boot time -approx. 1 minute till boot main path ends.
    I am trying to figure out what causes this long boot delay.
    I also use Acronis boot manager. This is a pre boot sequence which happens before windows boot starts. The recording I refer to happened after the acronis boot.
    This fits the actual time measurements I did which excluded the initial acronis loader.
    I counted the time it takes for the initial ‘boot turning dots’ and it fits the Boot Main Path time which is ~52sec.
    Part of this is due to autochk.exe (14 seconds) which keeps running every time.
    But I don’t understand what happens between Boot-Pre_fetch to Boot-sessioninit-phase? These are 21 seconds.

    Basically I’d like some guidance here as to what I should do/try

    I should also note that i found that:
    'autochk.exe' starts all the time. I’ve already tried to disable it using chkntfs /X C: D: E: F: (all my drives) and I see that under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager the autocheck for these drives is disabled

    What happens between Boot-Pre_fetch to Boot-sessioninit-phase? Which process is causing the delay as i can't find anything in the report.

    Memory usage is at 100% from boot start to winlogon? See the 2nd snapshot.

    There are 'unkown items' in the Disk Usage report (e.g. 4 sec usage in the last snapshot)

    I have coreI7, Asus PRIME H370 MB, Geforce 1080TI Another input is that I have 2 SSDs and 3 HDD connected to my PC as well as multiple USB devices I’ve uploaded the recorded boot here:

    Thanks for any help.

    How to use Windows Performance Toolkit to analyze slow startups

    Hello,

    I just installed the Microsoft Performance Toolkit for Windows 10 because I have a very slow startup and I wish to analyze it to understand which service/app/process is responsible for that. However I ma not
    sure how to use it. My understand is that I have to start a trace by WPR, reboot, stop the trace, and use the analysis tool (WPA) to get trace data in a graph format.

    Can anybody, please, publish step-by-step instructions to do that? I tried to use the Event Manager to troubleshoot the startup but it is not easy to understand if an error originated other errors or is originated
    by another error. Not all errors have to be fixed. Sometimes, fixing an error, remove all the errors it originated. So I would like to have a look at startup to understand if some process is responsible for time delays.

    Thank you in advance.

    I didn't find the right solution from the internet.
