MrJinje Posted February 12, 2010 Share Posted February 12, 2010 (edited) YesAt times Explorer.exe is known to do that.EDIT: But not for prolonged periods. Edited February 12, 2010 by MrJinje Link to comment Share on other sites More sharing options...

hakeem5454 Posted February 16, 2010 Author Share Posted February 16, 2010 I tried using your guide but its a bit unclear at some steps.I dont get the "stack counts by type" graph?i tried the summary table on the cpu by cpu graph but my highest count was "ntsokernal.exe" ?

MagicAndre1981 Posted February 21, 2010 Share Posted February 21, 2010 compress the etl file as zip or RAR and upload it to your public Skydrive folder or upload it on an 1 click hoster like Rapidshare.com and post the link here. Link to comment Share on other sites More sharing options...

cluberti Posted February 28, 2010 Share Posted February 28, 2010 No offense, but it's the weekend for me, and in general I stay offline during this time. I expect most others who frequent here do as well (given the relatively large dip in traffic from Friday afternoon to Monday morning). Be patient.

MagicAndre1981 Posted March 1, 2010 Share Posted March 1, 2010 Hi,the only spike I see from Explorer is the MessageLoop, where the Explorer handle all Windows messages and updates the TrayIcons. Which Shellextension do you have installed?André Link to comment Share on other sites More sharing options...

cluberti Posted March 4, 2010 Share Posted March 4, 2010 Well, I think Andre is right. In looking at the CPU usage, it's definitely a consistent spike, every second - one spike is ~2.5%, the next is ~7.5%, the next 2.5%, the next 7.5%, etc. I saw what appears to be the nvidia network driver in quite a few of the 7.5% stacks, but not in the 2.5% stacks (at least not to the level down I went), but I don't necessarily think that's the root cause - although it may be, as I've seen nvidia network drivers cause this. At any rate, to get to the data analysis, the top consumer of CPU in the explorer.exe process is shlwapi!WrapperThreadProc. The shlwapi binary is basically responsible for determining if a particular API call belongs to the shell (explorer.exe), or if should be handled by the browser, and then creates the thread requested in the context required. The WrapperThreadProc being the highest CPU consumer means something *else* running in explorer.exe is trying to create and process a *new* thread, every second. Since this isn't common to explorer.exe itself, I would have to agree with Andre - what explorer shell extensions do you have loaded, and are you running the latest drivers for the nvidia devices in your system? Also, if you disable Windows Search, does the problem continue (it's a fringe chance, but it's still possible that this can cause that behavior as well).
