2.5 Mins of Prefetching at Startup

[Guest]

Does anyone notice that after statup is complete, you get a 2 and a half
minute of Prefetching going on. There is a 2 and a half minute of constant
hard disk activity during this time and from the Reliability and Performance
Monitor, it shows hundreds of:

svchost.exe (LocalSystemNetworkRestricted)
svchost.exe (secsvcs)

The top one is related to Superfetch.
The second one is related to Windows Defender.

Does anyone else get this?
I did outline something similar on another topic but I now have a clearer
topic.

Yes, I haven't timed mine, but it sounds about right. However, why are you
concerned? According to the white papers I've read this activity has both a
low CPU priority and the lowest I/O priority, so there's no way it should be
affecting your use of the computer.

By the way, here are some screenshots:

The first one is a screenshot in the Reliability and Performance Monitor
during the Prefetching. The second one I just took now of the Event Viewer
because I wondered why there are lots of Boot and Shutdown Performance
Monitoring errors. Not sure if this related or if this is normal or something
I can fix etc.

It doesn't really affect the use of the computer.

The first 2-3 mins, of using it may be slightly slower than usual but not
overly.
I just don't know if the hard disk should be at high usage and Superfetch
spending 2-3 mins at startup every time. Didn't notice this on my Laptop that
had Vista although I took it back for another reason. I have had this
computer for 3 weeks and have noticed this usage for nearly 2 but that
doesn't mean it just happened, it may have been there all the time but I
can't remember.

I'm not sure why you are posting this again. Yes it's normal. What are you
trying to find out?

 

[Guest]

I want to know if everyone gets this and also the new information about
Event Viewer errors from my second screenshot.

Yes prefetch running at startup is normal. I don't know about the errors
you are getting, sorry.

 

[Guest]

Can you check if you get those Event Viewer errors?

This prefetching activity is perfectly normal.

How about the Event Viewer errors?
The Boot and Shutdown errors displayed there?
Does everyone else get these in the Event Viewer?

this screenshots is useless because you haven't expanded the file column to
see the full names

it's NOT the superfetch, but it's the system restore: a new system restore
is created every day at the first boot (These files are created at low IO
priority)

 

[Guest]

A few days ago, I disabled Superfetch and Defender and the activity stopped
at startup. I renabled it after.

 

[John Barnett MVP]

BillD, it's not system restore. System restore is disabled on my machine and
always has been but there is still a 2 to 3 minute disk activity after
reaching the desktop.

I agree system restore does create a restore point daily but it is set for a
specific time of day (I'm not sure of the exact timing). If your pc is not
in use at that time then system restore will wait until the next day. (or
next time period)

In the reliability and performance monitor (control panel>admin tools>
reliability and performance) on the Disk tab I am seeing only one of your
options and that is the svchost.exe (LocalSystemNetworkRestricted) I'm
seeing nothing else.

Can you find more detail from the actual event log entries. I see very
few errors or warnings on this machine. Seems odd that the shutdown
performance is a problem. It is possible that could be related to
motherboard drivers not being correct or maybe some other piece of
hardware, have seen that on one example but it may well be nothing to do
with anything in your case Check MB maker's website in case it
somehow has odd driver version.

I know it isn't System Restore as I know when it happens.
I see the process VSSVC.exe or something like that when it happens.
At startup, this isn't running but Superfetch is.

svchost.exe (LocalSystemNetworkRestricted) it the main one, the other one is
related to Windows Defender. If you don't have defender or you have disabled
Real-Time Protection, you probably wont get this service but the
LocalSystemNetworkRestricted is to do with Superfetch.

I still haven't got any reponce about the Events Montior.

Go to Control Panel, System & Maintenance, Performance Information and Tools.
Then click Advanced Tools and then click View Performance Details in Event
Log.

There is what I showed on http://tezmania.com/mypc/event.jpg
Do you lot have the same stuff there as on my screenshot?

 

[Guest]

It does seem related to 23rd of May rather than every day so it could just be
something small that happened but not sure what it was :S

I haven't seen either of those svchost PIDs on this system, that I can
recollect, and of the many running now none with those PIDs. The PIDs for
svchost.exe running now are: 1084, 1140, 1180, 1300, 1344, 1380, 1500,
1704, 2040, 2092, 2112, 2152. I'm not sure if PIDs for these services
change from system to system or boot to boot.

As to the errors, it's unclear what errors they are from the image you
supplied, other than Event ID 100. I do get those from time to time for
long boot times, usually related to when an update is installed that
requires a reboot. The initial shutdown, and subsequent start up take much
longer and generate this error for a longer startup.

Additional, none of the Event ID 100 events on this system are blank in the
General tab.
