Title: Windows startup degradation
Post by: Lisandro on June 19, 2015, 07:10:54 PM

I'm experiencing long boot times. Windows Events show:

A inicialização desse aplicativo demorou mais que o usual, resultando em uma degradação de desempenho no processo de inicialização do sistema:

Longer boot up here with the beta version, notification icons taking longer to show up, in addition to other minor issues, back on 2218 for now til new version final or I get brave and try another beta version hopefully with my issues fixed.

Hi Lisandro,

No, it's far better. Did you change anything or it was only greemlins?

Martin, do you have any tool to monitor the boot time?
Digging into Windows Events isn't easy and don't give a direct answer for the question: what is slowing down my boot?

Not forever, but longer than before.

To see what takes the time ..  This generates performance graphs to peruse at your leisure :) Example at the bottom



Download the SDK web installer from here  (http://msdn.microsoft.com/en-us/windows/hardware/hh852363)
Run the installer and select the following:

Leave the location to default

Windows Performance Toolkit 
(https://dl.dropbox.com/u/73555776/Wintoolkitselect.JPG)

You must reboot on completion of the install

After reboot set aside about 30 minutes when you will not need the computer

When ready start an elevated command prompt :

Go Start > All Programs > Accessories
Right click Command Prompt and select Run as Administrator

Then copy and paste the following command into the black box :

xbootmgr -trace boot -prepSystem -verboseReadyBoot

(https://dl.dropbox.com/u/73555776/sdk%20command.JPG)

Now your PC will be restarted 6 times. With a two minute pause before the tool runs after the desktop loads
After the second reboot the MS defragmentation program is running and is placing the files into an optimized layout, so that Windows will boot up faster
The last Reboots are training of readyBoot. After the training is finished, you'll notice a huge improvement in startup.

The logical prefetching described above is used when the system has less than 512MB of memory. If the system has 700MB or more then an in-RAM cache is used to further optimize the boot process (it’s not clear from the book whether or not this ReadyBoot cache completely replaces the logical prefetching approach or just builds on it, my assumption is that both work together).
After each boot the system generates a boot caching plan for the next boot using file trace information from up to the five previous boots which contains details of which files were accessed and where on the disk they were located. These traces are stored as .fx files in the

Confirm that.
