Windows 8 slow pre session boot

12 posts in this topic

Hello,

I just installed back Windows 8 and got a boot speed problem, i have found other topics about that, and ran Performance Analyzer.

I noticed a very very long time in Pre session, but I don't know where to find more informations, maybe one of you guys can look at my files and tell me where is the problem ?

Here are the url to the files :

- XML summary : http://online-legion.com/jayce/summary_boot.zip

- Full etl file ziped : http://online-legion.com/jayce/boot_BASE+CSWITCH+DRIVERS+POWER_1.zip

(full ETL file is still uploading, and will finish in about 5 minutes)

Thanks in advance for your time and help,

Best regards,

Jayce

PreSMSS is slow (120s):

+<interval endTime="122244" startTime="0" name="PreSMSS" duration="122244">

I can see that the kernel uses a lot of CPU during this time. You need to run this command:

xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -stackwalk profile -resultPath C:\TEMP

i need the stackwalk data to see what the kernel does.

ok, starting your HDD is slow:

Your driver version of iaStorA.sys is "12.8.0.1016". Try older drivers or use the Microsoft AHCI driver.

I am desperatly trying to uninstall that driver to get an older one or an other one, but once i uninstall it, I got a BSOD during PreSMSS.

Still trying to resolve this and post a new boot trace

EDIT:

Finally achieved rollback of named driver, to version 12.7.0.1036 (official one found on ASUS website for my MB) for the same boot time and following trace :

(upload will end 10 minutes after that edit)

thanks again

Jayce

EDIT 2 :

I tried out with 2 other drivers, an other INTEL and an ASMedia, boot time seems to shorten a little with those but is still long.

Here is correspnding trace :

the 12.7.0.1036 doesn't fix it. Still the same.

the last trace shows that the driver issue is fixed. Now Windows hags while enum die IDE controller:

<pnpObject name="PCIIDE\IDEChannel\4+20155ac6+0+3" type="Device" activity="Enum" startTime="556" endTime="47564" duration="47009" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 3" />

this causes a 47s delay.

I also see that the TPM driver causes a delay. Do you use TPM?

Hello,

What can I do for IDE issue ? plug off my old IDE drives ? My IDE drives are really tired, is it possible that the disk is the problem more than IDE channels ?

I did not really understood the concept of TPM (it seems to be a chip for security purposes), if I am using it i do not know I am :P

May TPM be disabled ? In BIOS ?

EDIT : I found that article on TPM, is it universal for all OS and platforms ? ( http://technet.microsoft.com/fr-fr/library/cc754524.aspx )

Thanks for your precious help,

Jayce

So, i removed my IDE drives and boot is really fast now, but i don't really know if this is my drives who got a problem or my motherboard with IDE channels :/

Here is the last trace without IDE drives, only 3 SSD drives : http://online-legion.com/jayce/boot_BASE+CSWITCH+DRIVERS+POWER_1_24_09_2013_1835.zip

And thanks again and again for your appreciated help dude !

How many drives are they?

Try with one at the time.

Check that they are NOT on "cable select", verify the jumpers on them to be set correctly.

boot is now fast (21s to UI and 24s to be fully booted)

- <timing bootDoneViaExplorer="21664" bootDoneViaPostBoot="34864" 

Enum of the IDE ports now takes 3.5s:

- <phase name="bootStart" startTime="16" endTime="3605" duration="3589">  <pnpObject name="PCIIDE\IDEChannel\5+23e44528+0+0" type="Device" activity="Enum" startTime="479" endTime="3490" duration="3011" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 0" />   <pnpObject name="PCIIDE\IDEChannel\5+23e44528+0+1" type="Device" activity="Enum" startTime="479" endTime="3490" duration="3011" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 1" />   <pnpObject name="PCIIDE\IDEChannel\4+20155ac6+0+0" type="Device" activity="Enum" startTime="479" endTime="1504" duration="1024" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 0" />   <pnpObject name="PCIIDE\IDEChannel\4+20155ac6+0+5" type="Device" activity="Enum" startTime="480" endTime="1495" duration="1014" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 5" />   <pnpObject name="PCIIDE\IDEChannel\4+20155ac6+0+1" type="Device" activity="Enum" startTime="480" endTime="1493" duration="1013" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 1" />   <pnpObject name="PCIIDE\IDEChannel\4+20155ac6+0+2" type="Device" activity="Enum" startTime="480" endTime="1493" duration="1013" prePendTime="0" description="Canal IDE" friendlyName="ATA Channel 2" /> 

During boot, starting the Firewall service is slow because of loading the rules (FirewallAPI.DLL!FwEnumRules).
