Cpu usage of X is so high
i use archlinux+xfce4 in my virtualbox , when i start xfce4 ,the cpu usage of X is 90% ro more ,what's up??
Running Arch in Virtualbox is often not the best indicator of actual resource usage, but have you installed the client additions?

Loud Portege M800 - CPU usage always at 50% or higher
Hi,
my laptop M800 always runs with fan at full speed, CPU usage runs between 50% to 100% even when no programs are running, is this normal?, seems the computer never seems to go to a resting or idle mode.
hope someone can help
cheersHi
Do you use your Portege with factory settings?
What you must do is to stop all useless processes that run in the background. This will reduce CPU usage.
By the way: change cooling method settings.
You can find it in advanced power plan settings > Toshiba Power saver > cooling method. Change it to battery optimized.
It will reduce cooling fan activity and notebook will run much quieter.
Test it please and post some feedback. -

ThanksHi,
As Jay already said, you can try the latest UWC patches (since you didn't tell us what you are currently running its hard to say if this will help) and if that doesn't work then get Sun PS to help you out (performance tuning is outside the support contract scope).
Performance tuning of your system is way beyond this forum. Given that this appears to be system 4 though (based on the the hostname) I would say that is this system is the only one with the problem there must be something different in either the load on the system, configuration of the system etc. that would explain the difference.
It's up to you to find out what the difference is.

Hi,
I have this 3750 old switch running c3750-ipbase-mz.122-35.SE5.bin (I know it is old...) and it is used for connecting remote offices via 10Mbps circuits. It has been running fine for the last 12-month. But recently, I found the CPU usage is a little bit high, like in screenshot.
I know the average CPU usage is only about 10-20% but it bothers me that it constant has MAX CPU usage around 90+%...I also did show processes cpu sorted and the only thing having 3+% CPU usage is spanning tree...but that won't be enough to cause the CPU peaks... There is no special feature configure on the switch, just VLAN taggings.
Any suggestions on what to check?Check SDM template if you are overloading the switch.
show sdm prefer
The current template is "desktop routing" template.
The selected template optimizes the resources in
the switch to support this level of features for
8 routed interfaces and 1024 VLANs.
number of unicast mac addresses: 3K
number of IPv4 IGMP groups + multicast routes: 1K
number of IPv4 unicast routes: 11K
number of directly-connected IPv4 hosts: 3K
number of indirect IPv4 routes: 8K
number of IPv4 policy based routing aces: 0.5K
number of IPv4/MAC qos aces: 0.5K
number of IPv4/MAC security aces: 1K
If the numbers are good then you might want to check the entire LAN and causing temporary STP loops that would kick your CPU utilisation once in a while. Since you have mentioned that you are using this switch for WAN circuits, you may also check the show platform output.
show platform ip unicast failed route
Total of 0 covering fib entries
You should see zero or else that wouldn't be good. -
Laptop fan runs all the time, broker runtime cpu usage after Windows 10 final upgrade
ENVY 17t-J100 Leap Motion, 16 GB RAM, i7, SSD primary, HDD secondary drives. Avast antivirus free. Windows Firewall. The laptop had Windows 8.1 and everything was great. I did the Windows 10 Home free upgrade on Day 1. Everything seemed fine. Fingerprinter reader and everything works. Great. But then I noticed that the fan was always running and the left side of the metal casing gets hot. In task manager heat map sorted by CPU usage, Broker Runtime is at the top. Not much ram, about 10 MB. But the CPU usage is always 20% and higher. Doesn't seem like much. But it makes the fan run all the time and the laptop heats up with it running all the time. Anyone else seen this? General internet searching shows this has been an issue with Broker Runtime since Windows 8 and not unique to any brand of computer. But it wasn't like this when I was using WIndows 8.1 One forum said it was the P2P Windows update feature and my laptop was sharing updates. So I disabled that and rebooted. No change. Now I see some people saying it is the Live Tiles features in the Start Menu. But I had live tiles with the WIndows 8 menu and no issues. The only way to disable Live Tiles globally is to edit the registry, and I shouldn't have to do that for this. And I like Live Tiles. So not sure that really is the issue either.

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.

Google Earth Plugin and LabVIEW: High CPU usage when adding placemarks
Hi,
I posted this question on stackoverflow earlier this week but feel it might be better suited to the LabVIEW community specifically so I'm reposting here:
I'm writing an application which uses the Google Earth Plugin to display events on the globe. Each event is a single point kml placemark with an icon which is a 3kb png file. Placemarks are uploaded to the plugin as they are received by the software. I am experiencing increasing CPU usage with the number of placemarks that are added.
I have tested displaying a new placemark every second and running until the software running the plugin completely froze (graph attached). The GEPlugin (green trace) stopped responding (i.e. the globe did not respond to the mouse) at around 1200 placemarks added and CPU usage was at ~30%. When the software itself (red trace) froze the plugin was using around 50% CPU and ~3700 placemarks had been added). After the freeze, no new placemarks were added which caused the software to respond (but not the plugin) so I could clear all the placemarks. After the placemarks were cleared from the globe, the CPU usage of the plugin returned to around 5% CPU.
So what I've seen is that GEPlugin CPU usage increases linearly with each kml placemark added. Is this the expected behaviour/ a normal limitation of the plugin? If not is there a more efficient way of adding many placemarks to the globe?
I am using GEPlugin version 7.1.1.1580 (API version 1.010) and LabVIEW 12.0f3
Please see the test results attached. Any input greatly appreciated!

Performance Log 020114_095115.png 82 KBHello,
I have had a look at your graphs and understood what you are trying to do. To me it seems that as the image gets more complex it gets harde to render which wold likely cause increase in CPU usage resulting in the freeze. I would suggest you try running the program on anoher computer to check on the RAM front of things. If this is a limitation of the GE Plugin then unfortunately I can not do much to help, but if you think this is a problem coming from your LabVIEW code then you can post your code here and I can take a look. -
Since 10.4.6 Update: "ATSServer" with high CPU-usage when opening PDFs
Since I've updated to 10.4.6 my system is very slow when I open PDFs (in "Preview" or "Acrobat").
This is caused by the process "ATSServer" which goes through every file in "~/Library/Fonts" (I have over 4.800 files there - but just a view are activated by "FontBook") and so it takes very high CPU-usage.
I didn't have this problem bevore the update and I didn't make any changes on my font settings.
I've cleaned the font cache, but it doesn't help.
Any ideas?
Ciao

PowerBook G4 17'' 1.67 GHz Mac OS X (10.4.6)
PowerBook G4 17'' 1.67 GHz Mac OS X (10.4.6)I haven't noticed any change myself, Dan, but I have the 2 GHz model.
One thing I HAVE noticed though after OS updates is that they can often result in a fair amount of file and free space fragmentation immediately after installation. OSX's routines will deal with fragmentation of small files , but not of large ones (over 20 Meg), and it won't deal very effectively with free space fragmentation. If your HD is getting full this can cause significant slowdowns, especially where video is involved.
You should also run DiskUtility and check for any directory and permissions issues.

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-( -
K8NGM2-FID problems: no usb and high cpu usage - HELP!
hi folks,
i've setup K8NGM2-FID inside an htpc with a clean install of mce 2005 (onboard video). For the past couple of days I've noticed a few things:
1) if the pc goes into standby (S3) and then wakes up, sometimes task manager shows a cpu usage of 50% (on the graph) but looking at the list of tasks (for all users) nothing is runing that high - in fact system idle process shows 98% (while the graph is still showing about 50%) and the system is a bit sluggish; reboot fixes this but it's getting really annoying. I've installed the latest AMD x2 driver. Sometimes it goes to 98-99% after waking up but that's been rare.
2) i've been getting a few BSODs lately, actually all started yesterday - 3 of them in a span of about 2 hours after insalling Nero. I'm going to try to figure out what is causing it that (proabably Nero - I hope since that's easy to undo) but what i've noticed is that when the system reboots after the blue screen, none of the USB devices work (i.e. keyboard, mouse, etc.). windows has to load, then I need to go in the back and unplug/replug the usb devices which then 'wakes' them up; this can get really annoying in a typical cramped home theater setup. software restarts seem to be good - ok hardware restarts are the problem. hooking things up to a usb hub has the same effect - i.e. I need to re-plug the hub to get them to work - it just means less things to plug/unplug.
has anyone else noticed this? help save my sanity - this is driving me crazy. since this is an mce setup, it goes into sleep and wakes up several times a day so the high cpu issue when it comes up really gets in the way of using the pc. btw. during high cpu times, no mce related function (record/watch/the shell itself) is running.
here's my setup:
K8NGM2-FID - boots up with 3 short beeps - I think it's 1 beep pause then 2 beeps
2 gigs kingston 3 CAS (2 x 1 GIG kit) pc3200 - boot screen shows it running at 400mhz in dual channel config
X2 3800+ stock fan/heatsink with silver 5 (runs around 35-38 idle - inside a silverstone 'stereo rack' case)
ms usb keyboard/mouse/mce remote
coolmax 550W power
3 140GB WD drives (ata 133 - not sata)
onboard video - framebuffer set to 128megs
latest (as of 2 days ago) nvidia and msi drivers - msi bios is the stock 3.0 (more on that later)
the bios settings are all default as far as I can tell.
pvr-150 tuner card
promise ata 100 card
nec 3500dvd
all running on mce 2005 with rollup 2 and all the updates windows could find
i haven't updated the bios because i've read about other folks having blue screen problems and the suggestion has been to up the voltage for the ram (I guess the default setup from MSI is lower than it should be) but apparently that option is missing from the 3.1 and later bioses? and reading the text file, it wasn't very apparent what the bios 3.1 was fixing other than a few cosmetic bootup texts. I'm planning to up the voltage later today.
anyhow, any suggestions short of throwing the entire pc out the door are welcomed.
thanks!ok here's what I've found about the high cpu...
using process explorer, hardware interrups is taking all the cpu. i've tried to disable items one by one but nothing is working so far. what does work is if i choose scan for new hardware, cpu goes down to normal. standby and resume and cpu is up again. do the scan and it goes down again - without changing anything.
i've re-installed the graphic board driver, nvidia 430 drivers, sound driver. not sure what else to do. checked my drives and they are all properly master/slave set.
this is really getting crazy...anyone come across this?
i'm a bit hesitant to go to bios 3.1 since i've seen lots of posts about BSOD and i've just gotten rid of that.
thanks
thanks a bunch! -

High CPU usage during 15 acquiring analog input and write to file (suggestion needed)
Helllo everybody,
I have a problem about the usage of CPU now i am using a realtime target (PXI-8186) with Daq (PXI-6259) to get 15 analog signals at the rate of 10kHz
at first i try to get signal at different rate but i found out that all of the channels share the same clock so i get the highest frequency that i desired after that i do
some data manipulation with displaying charts and use shift register to stack data in array of string finally i write the data to spreadsheet every 5 second, by doing this the CPU usage
is always 100% and reduce by the time the file is recordedto 71% or so and then start to increase to 100% again. I think the things that make CPU usage too high are
1. Time loop: because i set the period to be 10ms maybe this is too low.
2. The shift registered: may be it use too much overhead memory but i do not know other method to stack data before writing to a file
3. RAM too low: The RAM of PXI is only 256mb
4. Poor program arrangement: Because i am new to labview the program is not arranging correctly or i may use some inappropriate structure.
My program is very messy sorry about it because i avoid using SubVI and i am new to labview. Please help any suggestion is apperciated. Thanks in advance.
Best regard

target save.vi 328 KBIt looks like you are writing your data to disk every so often. For that reason, I recommend making it based on the number of samples you have instead of the time. With that you can preallocate your arrays with constants going into the shift registers. You then use Replace Array Subset to update your arrays. When you write to the file, make sure you go back to overwriting the beginning of your array. This will greatly reduce the amount of time you spend reallocating memory and will reduce your memory usage.

Having Issues with High CPU Usage with fluxbox & pekwm
Greetings,
I have searched for this issue and it seems that something similar has happened in the past with an old xorg, and it seems that someone is having a similar issue that they can point to kde as being the culrpit. However in my case, this is a fresh install and is not using any kde libs. Please allow me to explain the issue.
The power supply on my main computer finally gave out, and being incredibly poor at the moment I can not yet replace it. So, I pull out an older computer that I had once set up for my kids, but took it away from them when they were abusing it. I always make backup dvds and such monthly so I didn't have to worry about any lose of data, however I desired to keep my larger hard drives from my main computer. After testing to ensure that the hard drives were fine, I did some minor surgery, and did a fresh install of arch linux onto my back up computer. Since I prefer pekwm, I installed pekwm as my wm of choice, and outfitted it quickly with mpd+sonata, firefox, pcmanfm, and tint2. Then I rebooted into my pekwm 'desktop'.
It was running sluggish. Firefox was easily maxing the cpu up and beyond 100% and it felt ten times worse than any heavy DE I used in the past. I checked to make sure I had the right video driver installed. As this computer runs a 64MB nVidia GeForce2 MX with TV out video card, I searched nvidia's page and the arch wiki, noting that the driver needed is nvidia-96xx. Well I had already suspected that during install, and thus had installed such driver. I double checked my xorg.config and it has the right driver listed.
So I checked out some lighter browsers. I tried both Midori and Iron (which is similar to Chrome but without google spyware or whatever). Well both run better than firefox, Midori being the lightest one, but Iron quickly being my favorite. Still, the problem remained. Moving windows caused cpu spikes, opening more than one tab, or more than one program caused cpu spikes and the computer to slow down and sputter, freezing at times.
So I tried out another wm, fluxbos, which is another of my favorites. Seemed somewhat better but only fractionally, which I consider odd because pekwm has always seemed snappier than fluxbox to me in the past. Running lxtask (still mouse dependent, sorry lol), I was able to take note of the following...
FLUXBOX
lxtask 6% CPU usage average
PCManFM 5% CPU Average
Fluxbox 1% to 2% cpu usage
gksu 3% cpu usage
pidgin 3% to 7% cpu usage
firefox up to 62% cpu usage
midori up to 38% cpu usage
iron up to 50% cpu usage
mpd 11% cpu uage
Xorg (with no window movement) 2% cpu usage
Xorg (moving windows around) up to 80% cpu usage
PEKWM
lxtask 6% CPU
pidgin 7% cpu
tint2 1% cpu
pekwm 1% to 5% cpu
pcmanfm 7% cpu
firefox up to 85% cpu
python 1% cpu
midori up to 38% cpu
iron up to 25% cpu (odd...)
Xorg (with no window movement) 1% cpu
Xorg (when moving windows around) up to 80% cpu
Both were using around 118 MB RAm and weren't yet touching swap. As I see it I am thinking xorg or video driver related, yet I already made sure that I had the correct video driver. Here's my Xorg.conf

So what I am wanting help with is finding the solution to the cpu usage so that I can use this computer at least until I can afford a new power supply or whatever. I am open to any good suggestions, though I must state I am not really interested in tiling wm's at the moment. I am just not a true minimalist.
Thanks in advance for any and all help. I understand that there is a lot of info in this post, but it is my hope that with this info the problem can be solved. If there is info I didn't provide that is needed, please let me know.also check that you have
session.screen0.opaqueMove false
in your .fluxbox/init this will probably help a bit if it is currently true,

SBS 2011 - High CPU usage - Help me Microsoft forums! You're my only hope!
My company supports a client that has a SBS 2011 server. For about the past year, we've been fighting a recurring issue with performance on this server. There are about ten local users and four remote users. The server's CPU idles at
about 60%-80% but is usally running when under *any* load from 80%-100%. If you do anything on the console, it will stay pretty much at 100%. These are not power users by any means. The server is utilized for file/printer sharing, Exchange
2010, and one flat file database application (non-SQL). SharePoint is not utilized.
Needless to say, our client is frustrated. When opening files, using their database application, or doing anything Exchange-related, there is a large amount of lag on the client side. First, here are the server's specs:
Make:Dell PowerEdge T420
OS: SBS 2011 Standard SP1
CPU: 2 - Intel Xeon E5-2407
Memory: 32GB
RAID: RAID 1 - Operating System (C:)/Data Volume (E:) | RAID 5 - Data Volume (D:)
Here is what we have tried to resolve this to finality:
* Doubled resources - Initially the server had a single physical processor and 16GB of memory. While these specs alone should have been fine, and were fine when the server was installed, we had periods of time where the server would just sit all day at
100% usage. We doubled the resources and while this seemed like it would fix the issue, we are still seeing abnormally high processor usage.
* Removed all monitoring tools, antivirus, and backup software - As part of our testing, we removed our monitoring agent (LabTech) and antivirus (GFI Vipre). Mozy is utilized for an off-site backup so that was disabled. No dice.
* Verified updates - We made absolutely sure the server was 100% patched.
* Malware/Virus/Rootkit checks - We have ran scans checking for any potential issues with security.
* Ran MBSA and MBCA to fix any issues with the server's configuration.
There is no single process which is using all of the CPU, or we would simply be able to narrow it down. Our calls to Microsoft support have yielded no answers. The last call ended with Microsoft stating that a SBS server should always be running
at high CPU usage. Meanwhile, we have many other clients with less-beefy servers, with more users, who have no issues like these.
So, I'm turning to you all. I will gladly provide logs, configuration settings, even remote assistance sessions if you all can help shed some light on what might be causing my issues.
Thank you!Some comments/ideas:
How long was the server running after this screenshot? I ask because store.exe is only got a 1GB of RAM which is really low - it should grab most of the RAM within a few hours.
The server was up for about 12 hours. I believe an adjustment was made before to limit the Exchange memory usage.
Strange that SearchIndexer (wsearch service) is so high although that may be a startup condition.
The LT* processes seem to be a 3rd party monitoring tool - no idea why it would ever need that much CPU though (I thought you disabled this?).
We had, but we cannot go forever without monitoring our client's server. It has been pulled off in the past and results on performance are pretty much the same.
The taskmgr process run by amnet_admin has used a lot of total CPU Time. What is it? (can't see the command line).
That's the user I was logged in as when I took the screenshot. Even the task manager seems to eat up the CPU.
The sqlserver process right above it is also busy - may want to look at the command line and figure out which SQL database that is (SBS has 3 - WSUS, Sharepoint, and SBS monitoring)
I believe that's the SharePoint database. They don't currently use their site. Would you recommend a removal and reinstallation? I would not completely remove as I know SBS doesn't like you removing parts of the complete package.
Strange that vds.exe is 10% - that is the interface to the disk management interface IIRC. Perhaps your monitoring service has gone awry here - definitely lose it.
I'll see about pulling it off and I'll see if there are any improvements.

Hi everyone,
I'm having an issue with Word 2013 and I'm hoping someone can help. Seen as I got fleeced for my TechNet subscription this year (the price given on the invoice doubled when I called up to pay!) I’d very much like to see a speedy fix from the Microsofties
please! :D
Recently, I've found that Word will consistently exhibit high CPU utilisation, ~50% on a dual core second generation Core i5.
This continues, even when I’m not providing any input to or interacting with the Word window and even when the Word window is covered by other windows. Minimising Word causes its CPU usage to drop back down to zero.
The strange thing is that, so far, I’ve only observed this with a single document. I started writing this document at the start of this week and it’s been authored exclusively on Word 2013. In fact I’m the only one who’s editing it and I’ve only used a single
computer (and this one single install of Word 2013) to do so…
There’s nothing particularly unusual about this document, and a different but similar document which uses the same themes and features (in fact the theme for the second document was created from the first one) doesn’t appear to cause the same issues. Both
these documents are stored on SkyDrive, and are being edited directly from there.
Initially I tried the much recommended tweaks of disabling hardware graphics acceleration and sub-pixel positioning, however neither of these has had any effect.
I investigated a bit further using Sysinternals Process Monitor, and found that while Word is using a lot of CPU it’s actually looping very, very quickly polling for the existence of the registry key “HKCU\Software\Microsoft\Avalon.Graphics”.
This key doesn’t exist on my system, and a quick test I conducted where I created it just lead to Word looping polling for more non-existent registry keys.
My system is a HP Folio 13 running Windows 8 Pro x64 with Office 2013 (RTM, not Beta) 32 bit. Both Windows and Office are fully patched, as is everything else on the system.
Thanks in advance for any help anyone can offer.
ChrisHello again,
After working on my problematic document some more, I believe I’ve found the cause of the issue.
@Microsofties – I think this one is either a bug or a dodgy OOTB template…
I noticed that the high CPU usage only seemed to occur when the document’s footer was displayed. Experimenting with some careful scrolling and zooming to hide footer (without actually using the “hide white-space” option) seemed to confirm this so I investigated
the footer a bit more.
My document was using the standard Word “Facet (Odd Page)” footer template with a couple of fields added to suit my needs, namely “Publish Date” and a page number.
The template seems to be structured such that the content of the footer is inside two nested text boxes (one inside the other). I also noticed previously that this footer template also appears to “jump” up each page and back down again as I scrolled.
So I deleted the footer and its text boxes, and recreated the same content, in the same position (using the standard paragraph alignment tools) by hand without the nested text boxes. This has, so far, fixed the issue!
I also noticed that the CPU usage dropped right down to idle the moment I deleted the nested text boxes.
Altogether, this leads me to conclude that the “Facet (Odd Page)” footer template in Word 2013 is the source of my issue. Specifically, I believe that the use of nested text boxes in this template causes Word’s interactions with the .Net 4.5 WPF to go a
bit nuts, as evidenced by the infinite loop of request for the non-existent “Avalon.Graphics” WPF registry key I mentioned previously.
It would be nice to see some feedback on this one, Microsoft people, if only to know if this is actually a general issue or is specific to my document!
Thanks, Chris
