  1. This is an updated tutorial of the one cluberti posted here. To get started you need the Windows Performance Tools Kit. Read here how to install it: http://www.msfn.org/board/index.php?showtopic=146919 Now open a command prompt with admin rights and run the following commands: For boot tracing: xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Attention: Some users reported that they get a bugcheck (BSOD) when using the DRIVERS flag in the boot trace command. If you get this, use system restore to go back to a working Windows and run the command without DRIVERS xbootmgr -trace boot -traceFlags BASE+CSWITCH+POWER -resultPath C:\TEMPAlso change the name in the command to generate the XML. I've send some dumps to Microsoft, they look at the issue right now. For shutdown tracing: xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPFor Standby+Resume: xbootmgr -trace standby -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPFor Hibernate+Resume: xbootmgr -trace hibernate -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPreplace C:\TEMP with any temp directory on your machine as necessary to store the output files All of these will shutdown, hibernate, or standby your box, and then reboot to finish tracing. Once Vista/Server 2008(R2) or Windows 7 does reboot, log back in as necessary and once the countdown timer finishes, you should now have some tracing files in C:\TEMP. If asked, upload or provide the file(s) generated in C:\TEMP (or the directory you chose) on a download share for analysis. Analyses of the boot trace: To start create a summary xml file, run this command (replace the name with the name of your etl file) xperf /tti -i boot_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_boot.xml -a bootNow you see this picture.: You have too look at the timing node. All time values are in ms. The value timing bootDoneViaExplorer shows the time, Windows needs to boot to the desktop. The value bootDoneViaPostBoot is the time (+10s idle detection) which Windows needs to boot completly after finishing all startup applications. those values show you a summary. The MainPathBoot Phase PreSMSS Subphase So if the time takes too long for you, look inside the <PNP> node which driver is loading too slowly. SMSSInit Subphase So if the SMSSInit Phase takes too long, try to get an graphic card driver update. WinLogonInit Subphase If you have too long WinLogonInit Time, open the etl file and scroll to the service graph and look for a long delay. In this example the service SavService (Sophos Anti-Virus\SavService.exe) is part of the Plug and Play group and causes a delay because the service takes too long to start. Try to get an update for the hanging service or remove the software. ExplorerInit Subphase So if the ExplorerInit phase takes too long, make sure you minimize the services which use a lot of CPU power and make sure your AV Tool doesn't hurt too much. If it doesn't change the tool and try a different. The PostBoot Phase If post boot takes too long, reduce the number of running applications at startup with the help of msconfig.exe or AutoRuns. When you have a HDD (no SSD!) and you want to speedup the boot, run the optimization from this guide: http://www.msfn.org/board/index.php?showtopic=140262 Analyses of the shutdown trace: The shutdown is divided into this 3 parts: To generate an XML summary of shutdown, use the -a shutdown action with Xperf: xperf /tti -i shutdown_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_shutdown.xml -a shutdownOpen the XML and you see this: It shows you the most relevant data. <timing shutdownTime="23184" servicesShutdownDuration="1513">The shutdownTime is in this example 23s. Stopping the services takes 1.5s which is fast. Next you have an entry for all sessions. Starting with Vista, all services run in Session 0 (Session 0 Isolation) and each user gets his one Session (1,2,..,n). sessionShutdown sessionID="1" duration="3321">shows the time which it takes to stop all applications which the user is running. In this example it takes 3.3seconds. UserSession Phase sessionShutdown sessionID="0" duration="1513">The value sessionShutdown sessionID="0" shows the servicesShutdownDuration. So you can see which service takes too long to stop. SystemSession Phase In both cases expand the node and look at the shutdownDuration value. It helps you to identify a hanging application are service. KernelShutdown Phase To calculate the time spent in KernelShutdown, subtract the time that is required to shut down the system and user sessions from shutdownTime. In my example: KernelShutdown = 23184 - 3321 - 1513 = 18350 In this case the 18.35 seconds are very slow. In the <interval> you see an entry ZeroHiberFile which takes too long. In this expample the user enabled the Option ClearPageFileAtShutdown under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management to 1. This overrides the hiberbation file with 0 to delete personal data. This causes the huge slowdown. Setting this option to 0 would save 12.64 seconds of shutdown time. That is all you need to analyze slow shutdown issues. Analyses of the Hibernation trace:: To generate the XML, run this command: xperf /tti -i hibernate_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_hibernation.xml -a suspendAnalyses of the Sleep/Resume trace:: xperf /tti -i standby_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_sleep.xml -a suspendOpen the XMLs and look for long BIOS init times and services/application which take very long to suspend and resume. For deeper analysis refer to the Sleep and Hibernate Transitions part of theWindows On/Off Transition Performance Analysis Guide from Microsoft. The pictures Shutdown_cancel.png, Shutdown_picture.png and Boot_MainPathBoot.png were taken from this Windows On/Off Transition Performance Analysis Guide. Read it if you need more information. // Edit: 2010-11-28 Add the explanation of the boot process // Edit: 2010-10-11 added the optimization guide // Edit: 2010-10-09 If you get a BSOD (Bug Check 0x7E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) while making traces, REMOVE ALL USB DEVICES and reboot! When making a new trace remove the DRIVERS flag from the command line! // Edit: 2010-02-04 Added the -noPrepReboot command at shutdown tracing to prevent the preparatory reboot during a shutdown/rebootCycle trace. Usually, the reboot is required to ensure a consistent machine state before the first shutdown if multiple traces are being taken. // Edit: 2010-05-08 Added the link to the Visual Studio 2010 Diagnostic Tool as alternative download to get the Windows Performance Toolkit Installers. Added some pictures.
  2. Windows 10 cold boot fast, restart slow.

    So, this is my first post in the forum. The reason why I have to sign up here and post this topic is explained on the title. I won't write long post here. The resource for trace log is below. In case you need the <blah blah blah>.cab, I will upload too: https://onedrive.live.com/redir?resid=2EE5EFF21E741320!3950&authkey=!ACNd-yzlSDJLHlE&ithint=file%2ccab Right there, I saw that there are 2 kids caused the SMSSInit took too long to boot are: <file name="Unknown (0x0)" totalTime="61130" totalOps="257" totalBytes="12167168" writeTime="0" writeOps="0" writeBytes="0" readTime="61130" readOps="257" readBytes="12167168"/>and <extension name="(none)" totalTime="101917" totalOps="1006" totalBytes="160111104" writeTime="27256" writeOps="98" writeBytes="937984" readTime="74660" readOps="908" readBytes="159173120"/>Maybe there are some kids running around my laptop that I can't see. So you guys please help me solve this <beep> problem. EDIT 1: correct typo. EDIT 2: update .cab link EDIT 3: All the drivers are installed correctly. Also, ntbtlog.log shows that dxgkrnl.sys first successfully loaded and 4 times more fails. WdFilter one time more failed. summary_boot.xml
  3. This is an updated tutorial of my Windows 7 here. To get started you need the Windows Performance Tools Kit. Read here how to install it: http://www.msfn.org/board/index.php?showtopic=146919 Now open a command prompt with admin rights and run the following commands: For boot tracing: xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPNote, in Windows 8 it is safe to use the DRIVERS flag, the Windows 7 bug is fixed in Windows 8. For shutdown tracing: xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPFor Standby+Resume: xbootmgr -trace standby -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPFor Hibernate+Resume: xbootmgr -trace hibernate -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPreplace C:\TEMP with any temp directory on your machine as necessary to store the output files All of these will shutdown, hibernate, or standby your box, and then reboot to finish tracing. After you login to your PC, the new startscreen is shown and you have to click to the desktop to see countdown timer. Again, wait until the timer finishes. Afetr you did this you should now have some tracing files in C:\TEMP. Analyses of the boot trace: To start create a summary xml file, run this command (replace the name with the name of your etl file) xperf /tti -i boot_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_boot.xml -a bootNow you see this picture.: You have too look at the timing node.

If it doesn't change the tool and try a different. The PostBoot Phase If post boot takes too long, reduce the number of running applications at startup with the help of msconfig.exe or AutoRuns. if possible, you should always use the new Fast Startup/ hybrid Boot of Windows 8. At the end of this guide you'll learn how to analyze this new mode. Analyses of the shutdown trace: The shutdown is divided into this 3 parts: To generate an XML summary of shutdown, use the -a shutdown action with Xperf: xperf /tti -i shutdown_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_shutdown.xml -a shutdownOpen the XML and you see this: It shows you the most relevant data. <timing shutdownTime="23184" servicesShutdownDuration="1513">The shutdownTime is in this example 23s.

This overrides the hiberbation file with 0 to delete personal data. This causes the huge slowdown. Setting this option to 0 would save 12.64 seconds of shutdown time. That is all you need to analyze slow shutdown issues. Analyses of the Hibernation trace:: To generate the XML, run this command: xperf /tti -i hibernate_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_hibernation.xml -a suspendAnalyses of the Sleep/Resume trace:: xperf /tti -i standby_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_sleep.xml -a suspendOpen the XMLs and look for long BIOS init times and services/application which take very long to suspend and resume. Windows 8 includes a new boot mode called Fast Startup or Hybrid Boot. If this boot mode is slow, you have to run this command to trace the slowness: xbootmgr -trace fastStartup -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPI've already explained how this mode works. First Windows shuts down the users, next Windows hibernates the kernel with all drivers and the services. Next the PC shuts down. Now Windows boots again, read the hibernation file and resumes all services and drivers and next you go to the Logon screen. So we now need to view all 3 actions. So first look is the closing of apps and logging off the users takes too long. Create the shutdown XML with this command: xperf -i fastStartup_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_shutdown.xml -a shutdownOpen it and you'll see this: Note, that the file only shows the logoff of the user sessions. Here check which programs take long to close. The FlushVolume is writing open files/cache to the HDD. Next, we must look if the hibernation is slowly. To generate the XML run this: xperf -i fastStartup_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_hibernation.xml -a suspendOpen it and you'll see this: Now the same applies like Hibernation. Look which services or drivers take a long time to suspend. Also note, that those values are in µs! If those 2 steps are fine, we must look at the new Startup. To generate the XML run this: xperf -i fastStartup_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_Boot.xml -a bootOpen it and you'll see this: When you compare it to the normal boot, you see some differences. The PreSMSS and SMSSInit Subphases are gone. This is replaced with SystemResume. If this takes a very long time, open again the summary_hibernation.xml and look for devices are services which take long time to resume. The rest of the boot is the same like the normal boot. If WinLogonInit are long, check the Group Policies and if you're restoring of network connections. And if PostExplorerPeriod is long, you also start too many desktop programs or your new Windows 8 apps take too long to load the data to show in the live tiles. I hope, this helps you to fix your Performance issues with Windows 8. The pictures Shutdown_cancel.png, Shutdown_picture.png and Boot_MainPathBoot.png were taken from this Windows On/Off Transition Performance Analysis Guide. Read it if you need more information.
  4. Windows98SE CPU problem.

    Hello reader, I've got a windows 98 SE problem: I installed windows 98 on a Thinkpad T-21 which has a Pentium III around 600 Mhz if not more, a few days later I moved the hdd to an other laptop, a Compaq Armada E500 and windows started to install and (I think) change cpu drivers, it suddenly talked about 'installing Pentium II stuff bla.' A few hours later I moved it back to the T-21 and those E500 drivers are still there ! Z-cpu now only gives 200mhz ! and it is really slowing down the laptop, I only expirienced this recently for some reason, (I did the driver swapping a few days ago.) Could I have any help with this ? is there a way to change the drivers, or do I have to make a dirty or clean install ? I can give you a list of system drivers if you want. Thanks.
  5. Hi, My Windows 7 takes 13 seconds of a cold boot (Shutdown to Desktop, No hibernation enabled) I am once again giving Windows 8 another shot after some time...And unfortunately..No enhancement, Boot time is the same as it was when i last uninstalled it... My Windows 8 Restart (Forget about the hybrid/fast boot) from windows logo to desktop in 27 seconds! that is 14 more seconds than Windows 7! I am really bothered with that issue, I really don't know what is causing that delay from the time Windows logo start to desktop... This is a fresh UEFI / GPT install of x64 Windows Pro on a SSD drive using Intel RAID / AHCI driver, Latest BIOS, latest sound drivers... My mobo is an Asus Rampage IV Formula Bios 4004, GTX 690, 8 GB RAM. Here is the summary_boot.xml file..BTW my .ETL file is 148MB...not sure if that's normal or not... I hope somebody help me find out what is causing all this delay... Thanks in advance! summary_boot.xml
