TheCyberMan · Jun 9, 2012

Thanks for the update i will leave you to it.

I'm sorry if I was a bit blunt, but I was tired, and I know how to do port forwarding etc (bad day I guess).

Skype & Team Viewer were both running, per View attachment 765

Java Scheduler looks like it's hanging -

Code:

 jusched.exe  4,620 K Not Responding

Remove all versions of Java; reinstall - http://java.com/en/download/ie_manual.jsp?locale=en

removing and reinstalling java seems to have made the lag spikes more frequent

Cl0ttERS · Jun 11, 2012

hmm how do you properly disable wmpnetwk.exe ?

Argh several svchost processes are spiking randomly now >_< So hard to listen to music

Go to Services and disable the Windows Media Player Network Sharing Service.

Also, do the lag spikes recur when you just uninstall Java?

Cl0ttERS · Jun 11, 2012

I'm not entirely sure - but I do know that they have become more frequent since the reinstall

I didn't notice a massive spike after uninstalling - I also have the Java SE Development kit installed just to note

Corrine · Jun 11, 2012

Do you have any old versions of Java still on the computer? If so, uninstall, leaving only the most recent.

Cl0ttERS · Jun 11, 2012

I removed all Java versions and reinstalled the latest version

Open up Resource Monitor. I used it today to solve a lag problem on a Dell (it was the Dell DataSafe app and it's associated internet access').
Found it by noting the regular HDD usage spikes.

Hi, If you look at the DLL's associated with svchost in my last post many problems occur because a dll is unregistered, this is a simple batch to register most of the relevant dll's has worked to fix your problem in the past. Open the attached .zip file and right click on Lag.bat select run as administrator, restart afterwards, let us know how you get on.

I can't help thinking that you should put a health warning on that file :)
It does a lot more than just re-register DLL's - forcing deletion of the %temp% folder content can cause problems, and the consequences of effectively deleting the catroot2 and DataStore folders should be explained.

Cl0ttERS · Jun 13, 2012

Yeah you should probably add

echo WARNING THIS BATCH FILE WILL DELETE THE TEMP. FOLDER, AS WELL AS CLEANING CATROOT2 AND THE DATASTORE
echo Please confirm you want to do this by pressing any key, otherwise close the window
pause

/* regsvr calls */

Hi, this fix was from a MS development engineer who showed it at a conference I attended, it is perfectly safe, those functions are part of windows update problems AND can be the cause of high cpu useage in svchost. Why? well the windows update by default will run with high priority and even though the service may show started it is actually not,the priority is called by the bits service, so this is designed to repair that function it will do no harm.

usasma · Jun 13, 2012

FWIW - I've used this batch a couple of times and have sufferred no ill effects from it.
Still have the hair on my palms tho' :0)

Cl0ttERS · Jun 13, 2012

I know what the regsvr command does (perfectly safe), but sometimes erasing the temp directory is not a great idea without warning. I scanned through that batch and actually missed the del temp line - I don't care, but I reckon some people will be annoyed/have temp files they want/need

Jenae · Jun 14, 2012

Hi, this is simply not the case, by their very nature these are temp files, and if you understood that, why would removing them be any reason to get upset? What circumstance could you enlighten us with in regards to "some people will be annoyed/have temp they want/need... makes no sense at all.

Cl0ttERS · Jun 14, 2012

Well, when I am coding something that outputs to temp its useful to see if temp files have been created, and if they are in the correct format etc, true I wasn't debugging/looking for anything at that time, but I could have been :)

I suppose its a tiny window for error, but meh xD

On a related note, the batch file does not seem to have changed/fixed the problem

Jenae · Jun 14, 2012

Hi, what happened with resource monitor specifically reliability monitor may shed some light on this.

Cl0ttERS · Jun 15, 2012

SSDPSRV
LanmanWorkstation
NlaSvc
Dhcp
MsMpSvc

All spike ^ this is pretty much in order of severity SSDPSRV was using at least 20% CPU at that point
(Resource Monitor)
