SSD Speed Normal in Safe Mode But 30% Slower in NORMAL Windows Mode RRS feed

  • Question

  • Good day,

    My SSD Speed is Correct in Safe Mode But 30% Slower in NORMAL Windows Mode. I have compared the Start Up items using Autoruns but can not decide what to disable. 

    I can send you my COMPARE.AM file for your reference if you wish.

    Thank you

  • It is really weird that in safe mode speed is better then in regular mode..

    In case like this the best tool to use is WPA. Windows Performance Analyzer. it has a boot log option that is used to record everything happens during the boot phase which may slow down the system. WPA is part of the Windows Resource kit.

    Even with Process Monitor boot  logging you can probably find the culprit, but WPA is probably better at this..

    Start with this query:
    https://www.google.com/search?safe=off&source=hp&ei=UJZfXeXAEYXcwAKZiY3oDw&q=wpa+boot+analysis&oq=wpa+boot+&gs_l=psy-ab.3.2.0i22i30l8j0i22i10i30j0i22i30.1909.3299..6638...0.0..0.89.714.10....2..0....1..gws-wiz.....10..35i39j0j0i203j0i10i203.8TurSAc7knA

  • Thank you for your kind reply. I do not think that I will find the culprit using this method because I need to know what is affecting my SSD speed. 

    This method shows me what is booting but does not point to the culprit for the slow disk speed. Any additional assistance is appreciated.

    The problem is that the SSD performs 30 percent slower than it should during Windows normal operations and not the boot up.

    Thank you

  • Hello jaz111,

    I would suggest checking which legacy file system filter drivers and file system minifilter drivers are in place when Windows is in "normal" mode.

    One way of doing this is to examine a live dump of the system:

    The above shows no "legacy" file system filter drivers (apart from FltMgr, which supports the file system minifilter architecture) and five file system minifilter drivers - all Microsoft standard (Microsoft antimalware file system filter driver, Windows Container Isolation FS Filter Driver, LUA File Virtualization Filter Driver, Windows Overlay Filter, FileInfo Filter Driver).

    If you have more filter drivers than above, then one could focus the performance analysis on those filters.

  • Sir,

    I appreciate your INSTRUCTIONS but how do I go about getting a DUMP file to check?

  • without recurring to a full memory dump, there is a tool to collect those information. simply run this command:

    FLTMC instances

    Thanks

    Wednesday, August 28, 2019 12:05 PM
  • Hello Mario,

    Thanks for that information - I did not know about that command. It is certainly the best way to start investigating an issue like this. The !devstack on the DeviceObject and the DiskDeviceObject (which I forgot to show) are also possibly worth looking at if fltmc.exe does not find anything interesting.

    BTW !devstack on the DiskDeviceObject looks like this:

      !DevObj           !DrvObj            !DevExt           ObjectName
      ffff9a83558e8060  \Driver\volsnap    ffff9a83558e81b0
      ffff9a83556d6e00  \Driver\volume     ffff9a83556d6f50
      ffff9a835570d8f0  \Driver\iorate     ffff9a835570da40
      ffff9a83558e6050  \Driver\fvevol     ffff9a83558e61a0
    > ffff9a83556ef910  \Driver\volmgr     ffff9a83556efa60  HarddiskVolume3

    These are the drivers through which NTFS writes to disk pass (such as fvevol - BitLocker Drive Encryption Filter Driver).

    The value of this approach depends on jaz111 having correctly identified file system performance as responsible for any perceived slow down. If pure file system performance is not solely responsible then other approaches to analysing system performance might be more appropriate.

  • yep.. it is very strange that in safe mode it is quicker than in normal usage..

    unless there is really a device driver for the disk which runs only in when starting normally and it is a bad bad driver..

  • Hello,

    I have run AUTORUNS in SAFE MODE and NORMAL MODE and have the compare file available if you wish to view it. Thank you.

    Thursday, August 29, 2019 6:37 PM
  • Hello jaz111,

    Apart from an additional CldFlt (Cloud Files Mini Filter Driver), you have the same file system minifilters as my laptop - nothing suspicious there. We have not checked legacy file system filters and disk filters, but I don't think that we need to do that as this stage.

    You confidently say that "SSD Speed Normal in Safe Mode But 30% Slower […]" - how did you measure this performance impact? Did you just measure the total duration of some activity that involved disk usage, or did you measure disk speed explicitly? In the former case, many factors might influence the result.

    There are techniques for measuring the time between initiating a file system request and its completion. I used Event Tracing for Windows (ETW) to obtain this trace of a file copy:

    I could see from the trace that there was no there disk activity and the time taken to read/write one megabyte chunks of a file in units of 100 nanoseconds (the Duration column, 5245 = 524.5 microseconds = 0.5245 milliseconds). If measures of this type show a substantial variation between safe and normal mode, then I would concentrate on filter drivers - as we have done until now. If however, I just notice that the total copy time varies then many other factors may be playing a role and a different approach would be needed to understand the performance loss.

  • Hello Gary,

    "You confidently say that "SSD Speed Normal in Safe Mode But 30% Slower […]" - how did you measure this performance impact? Did you just measure the total duration of some activity that involved disk usage, or did you measure disk speed explicitly?"

    I used CRYSTALDISKMARK 6 to measure the SSD speed explicitly. It is a Samsung 970 Plus 1 TB drive. I can post Test Results if you wish.

    I have no idea how to use Event Tracing for Windows but I can follow your directions or that of a web page if you can post a link. 

    Thank you.

  • I don't know about Samsung but Crucial recommend using the standard Microsoft drivers with their SSDs.

  • There are many thread about this model be slow on boot..

    Someone suggest to disable "alienware sound center"..

    I have a dell workstation and the official Dell documentation says that it support a max of 500GB of SSD. Alienware is Dell now and don't know if by any chance the same limit apply now.
    I also had lot of problem with the storage until I setup the machine to boot as UEFI. It's unclear from your data above if the system boot is UEFI or Bios. If it is BIOS, try change to UEFI and create the partition of your disks as GPT. It helped me..

  • Hello,

    My device IS already set to UEFI. I have also tried it in AHCI format. Slight speed increase using AHCI vs. UEFI. 

    Also, I have used Samsung NVME Driver and Windows Native Driver with no change. Note: Samsung NVME Driver only works in AHCI mode and is not recognized in RAID.

  • Then why don't you try taking two boot Procmon trace and share them to compare..

    Start Process Monitor, select the Option "Enable Boot Logging", reboot, logon restart ProcMon and save the trace without any filter applied and in native PML format.

    Then "try" the same thing in safe mode.. I'm not sure that the procmon driver gets loaded in safe mode, but you can try.. if it works share both the trace, if this doesn't work share just the normal boot trace so we can have a look trying to find any bottleneck..

    Thanks

  • Hello,

    Downloaded and ran Procmon in NORMAL mode. I received nine files called bootlog.pml, bootlog-1.pml through bootlog-8.pml. File sizes are approximately 350MB in size each.

    Which ones do you wish to see and how do I send it to you?

    Procmon does NOT load in SAFE mode.

    I also have ntblog.txt available if you wish.

    Thank you.

  • Other things I noticed..

    Most of the time is spent in the SVCHOST 2704, which is the FontCache service.

    Effectively as you can see from the stack, all the time is spent under the Filter Manager driver, and probably is one of your driver we were discussing last time..

    So, please, have a look at your font folder, may be it is full of old windows 7 Font.. If it is not, then it is one of the driver you are using to access the disk..

    Looking at the operation count, the MBBService is also problematic.. it read from the registry 130000 times..

     So, please look at the font folder and disable all the services I already told you..

    Also look at this article: http://www.ryli.net/ssd-is-slow-find-the-right-way-to-fix-it/

    and execute fsutil behavior query DisableDeleteNotify

  • On my system I have 192 fonts.. you have 612, but don't think the number is the problem..

    I think you may have one device driver which doesn't work very well with your SSD.

    You said "I have run AUTORUNS in SAFE MODE and NORMAL MODE and have the compare file available if you wish to view it. Thank you."

    Yes, this would be helpful at this point..

    Thanks

  • Hello,

    I am trying to DISABLE listed services now. Will Post back.

    Regards fonts...is there any way to check for UNUSED fonts and then to uninstall them?

    "mbbservice.exe" program and file Uninstalled.

  • The autoruns file are useless because they registered the configuration of the system and not the "actual" loaded drivers..

    Use Process Explorer. Select the System Process, then select Show Lower Pane and Show DLLs.

    You will see the actual loaded drivers in the OS. Press the Save button, and a file with the actual loaded Drivers will be saved.

    Compare the loaded drivers between safe mode and standard mode. 

    Look to see what driver is missing in safe mode from the list you provided before:

    WdFilter, storqosflt, wcifs, CldFlt, FileCrypt, luafv, npsvctrig, Wof, FileInfo.

    If there is a missing driver in safe mode, probably that is the culprit of the problem.. try disabling it for the next normal run and see what happen..

    Here is LINK for Processor Explorer as you requested...

  • Lot of differences between safe mode and normal mode.

    Of the above only 2 were available in safe mode: Wof and FileInfo.

    All the other are available only in full mode: WdFilter, storqosflt, wcifs, CldFlt, FileCrypt, luafv, npsvctrig

    So, maybe the problem is just that the number of driver used in normal mode add a slowness of 30%.

    Try disabling one by one these drivers, WdFilter, storqosflt, wcifs, CldFlt, FileCrypt, luafv, npsvctrig and see what driver causes the worst performance hit..

    Thanks!

  • Hello,

    Completed majority of your steps with No Change.

    FileCrypt is a file system driver. In Windows 10 it is starting at Kernel initialization. If FileCrypt fails to load or initialize, Windows 10 attempts to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration cannot be applied or working improperly, Windows 10 startup process halts with a Stop error. If you disable or delete the FileCrypt service, Windows 10 won't start.

    One Drive Uninstalled CldFlt

    Windows Defender Disabled WdFilter

    LUAFV.SYS Information
    This is a valid program that is required to run at startup.

  • I noticed also that when the system start in safe mode, a lot of storage drivers are loaded but probably not used because unnecessary..

    it seems then that the mandatory driver when windows is started normally, add a 30% of overhead.. which may be a lot or not depending on the situation.. I think it is reasonable having some overhead when the system is working at his best, because it will need to handle more corner case and exceptions than not when working in safe mode.. don't know if it is by design, but for sure it is expected that when running windows completely the fact that it loads all the programs and services and system drivers, will slow the system down.. 

    Thanks!

  • Hello Mario,

    While I understand your opinion, I disagree. I say this because I backed up and then did full W10 Reinstall, Updated it and it ran Perfectly with No Loss of SSD performance.

    This effectively eliminates the Normal Mode driver as the culprit. I even Disable the Meltdown and Spectre Update and noted a 20 % increase across the boards. Go figure.

    Sir, May I ask if you have any further recomendations?

    Thank you.

  • The only thing that comes to my mind when you have performance problem like this is to run WPA, Windows Performance Analyzer.. it has a boot mode analysis that helps track down eventually bad drivers..

    So, if it happens again, try using WPA other than reinstalling from scratch which may help as always :-)

    Also, always use UEFI and GPT if possible.

    Thanks!

  • Sir,

    FINALLY finished downloading WPA. What do you wish me to do with it? Thank you.

  • But do you still have the problem?

    I understood you finally reformatted the machine from scratch and now it works fine, correct?

    So, just in case and for future reference, If you still will have the problem, you have to start WPRUI.EXE as administrator, on the right of the window select Performance scenario "Boot", detail level "Verbose", Save to "File". On the left select some options as shown below:

    Number of iterations leave it to 3.. this will collect three different traces after three different boot s o we can compare if there is any difference..

    Then share the collected traces..

    THANKS!

  • Sir,

    Thank you for your prompt reply. Will complete tasks as you ksuggest and post back.

    May I ask if you have seen any references online regarding Windows 10 Debloater solving Performance issues? No one can say why this solution worked but several say it solved their problems.

    Thank you

    Tuesday, September 10, 2019 10:04 AM
  • Well, generally speaking every tool that help removing third party bloat software may help.. sometimes they help a lot, sometimes they broke the machine if they are not written really well..

    But if you now have no longer any performance problem, don't go through the cycle of taking the WPA traces also because we won't find anything useful if now you don't have any more problem..

    Thanks!

  • Dear Mario,

    Yes, I still have performance issue. I only formatted and reinstalled for Test Purposes. I am back to my Original image. I have too many programs to reinstall and some have no disks any longer.

    Will continue to troubleshoot.

    Thank you.
    Tuesday, September 10, 2019 3:32 PM
  • Hello Sir,

    I completed the WPA traces. The files are 13 GB in size. I have no way to upload such large files. Any suggestions?

    Thank you.
