Help with regular cpu usage spike

im running a VI thats reading data off a mouse through a VISA driver. i get these strange spikes in cpu usage which are regular at ~12-13 second intervals, which i haven't got a clue as to the cause.
any ideas??

hi all,
thanks for the suggestions. ive looked with sysinternals, and it appears to be a very minor increase in labview cpu usage - i closed all antivirus related processes, and the spike still continues, so it doesn't appear to be that...
ive attached the vi, in case its some stupid coding issue..
apologies for being so ignorant, but how would i go about checking if it's some issue caused by a windows update or whatnot..

Queue consumer stops with 100% cpu usage

I'm trying to use Berkeley DB queue with transactions. When I tested what happens when transactions with DB_APPEND are aborted I found that while it works and DB_CONSUME correctly skips over rolled back records, unfortunately extents that have those records are never deleted, which causes database to always grow. Next I tried DB_CONSUME with database opened using DB_INORDER flag and it seems there's a serious regression in Berkeley DB that causes it to loop indefinitely with 100% cpu usage when it encounters a rolled back record. I tested various versions and found that this bug doesn't happen with 5.1.29, but it is reproducible with 5.2.42, so this regression might have been introduced in 5.2. I have also tested 5.3 and 6.0, and both have this behavior. There may be something wrong with the way queue records are rolled back, one indication of that would be that in 5.1.29 doesn't have neither of the two problems I found with DB_QUEUE: extents are deleted after being consumed, and there are no issues when consuming with DB_INORDER either.
You can find Python code to reproduce this issue here:
https://gist.github.com/snaury/027a3c546f5b0a62a440
Sorry for using Python and not e.g. C++, but it's a lot shorter that way.

We have looked at the issues and they are valid. We will roll the fixes out for this in our next release of BDB. The test case was very useful and really helped to speed the process up. If you have any questions, please contact me directly at [email protected] Thanks again for bringing this to our attention.
thanks

Simple Java 3D programs CPU Usage spikes to up to 90 percent!

Hi, everyone. Im completely new to Java 3D and Im toying around with basic program structure right now. My code is based off of that in the first chapter on 3D in Killer Game Programming in Java. I removed most of the scene elements, replacing them with a simple grid, Maya style. (Yes, Im starting off small, but my ambitions are grand I intend on creating a polygonal modeling and animation toolset. After all, the Maya PLE is dead damn you, Autodesk! and I just plain dislike Blender.) I implement a simple OrbitBehavior as a means for the user to navigate the scene. That part was basically copy and paste from Andrew Davisons code. The mystery, then, is why the programs framerate drops below 1 FPS and its CPU Usage spikes to up to 90 percent, according to the Task Manager, when I tumble the scene. Id appreciate anyone taking the time to look at the code and trying to identify the problem area. (Ive undoubtedly missed something totally newbish. -.-) Thank you!
(Also, I had the worst possible time wrestling with the posting process. Is anyone else having trouble editing their posts before submitting them?)

Huh. A simple call to View.setMinimumFrameCycleTime() fixed the problem. How odd that there effectively is no default maximum framerate. Of course simple programs like these, rendered as many times as possible every second, are going to consume all possible CPU usage...

JDev 10.0.1.3 CPU Usage Spikes - Somewhat Serious!

I have noticed that JdevW.exe process in task menager has annoying CPU usage spikes every 2-3 seconds. This does NOT happen if I use 10.0.1.2 version.
I have fairly powerful Dell workstation. Any ideas? Configuration problem?
BTW embedded OC4J is not running.

Shay,
I am actually not doing anything. As soon as I open JDev I can see (and feel) that performance problem. Every time the 'spike' occurs, mouse gets 'frozen' for a fraction of a second. It is anoying a bit.
My coworker's installation do not have that problem and I wonder if add-ons that I have downloaded and installed would create this behavior. BTW, how do I figure out what add-ons (plugins) I got?
I can see 'jucheck.exe' and 'jusched.exe' processes as well but even when I killed them the spikes occur.
Any thought?

When I run activity monitor with no programs running my dock shows fluctuating usage...between 4% up to 20%. Random figures that come and go with corresponding CPU usage. A little help?

My activity monitor show random and fluctuating CPU usage at the Dock site with absolutelyno programs running. %'s fluctuate between 3 - 20 and they pretty much come and go. What might be causing this?

There's a lot of background processes running that aren't documented as Apps as such. And some of them are the Time Machine backups, Spotlight searches, all kinds of small little bits of maintenance caches, there's a lot going on. So it's not completely out of the question that this is 'normal' for a Mac. If it were 50% or more I would be concerned but if it spikes up to 20% for a second or two you are probably not in any trouble of any kind.

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,

CPU Usage Spikes - Crashes ITunes

I've been using Itunes for about a year, and over the past week, my CPU usage will spike at 100% while playing Itunes, causing the song quality to skip and play as if it was a scratched CD. I updated from 4.9 to 5.0 (erasing all existing Itunes programs first) and the problem still happens. I'm not running anything else other than Itunes, and the usage still spikes to 100% causing the problem.
Please help!

I'm having the same problem. I've isolated it in a number of ways trying to resolve it.
It always happens 13 seconds into playing a track. This applies whether it plays from the beginning, 1 min into the track or if I make is jump to different places. Each time, once it has played 13 seconds (ie first 13 secs or if I jump to 1 min immediately it will be at 1:13 or if I play 6 secs then jump to 1:30 it will happen at 1:37). The CPU spikes to 100%, pausing everything and leaving a 3 or 4 sec silence.
This happens regardless of track length. So a 1 hour dj set will have the CPU spike at 13 secs and then be fine for the next hour.
It seems to me to be related to some sort of buffering or something similar in Itunes. I have worked out that once it has caused the CPU spike I can restart the same track and it will play through without a hiccup. If I play the next track and then come back to the first track, though, it will glitch at 13 secs again. I can also make it glitch on a replay of the first track without playing any others by changing the tracks that are to come after it in the playlist. This seems to suggest it is related to buffering the coming track(s).
I can make the silent gaps go away by reducing the size of my music library considerably. It is over 45 gig now. If I reduce it to below 20 gig the CPU spiking occurs but not at 100% and so not causing the silences. The problems is still there, though, and itunes has played my 40 gig library fine for months without any such problems.
Recent changes have included a few software installs. I have removed those that I could (eg Nero) but I do still have one photo editing programme that I need for a current job. I had removed quicktime from my startup but seeing a suggestion that this caused such a problem I have put it back. This has not fixed the problem for me.
I have also bought a shuffle and would have probably run the software related to that. If you had a problem when you added a mini perhaps it's due to some sort of error arising from the software coming with new ipods when used with existing itunes installations? Just a guess.
I'm running Itunes 4.7.1.30. I had thought about upgrading to 5 but it seems to be causing more problems and it seems it doesn't resolve this one.
If anyone can help with this I would be most grateful as it is making Itunes unusable on my computer. I'm going to have to go back to playing cds!!!

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?

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.

CPU Usage Spikes

My computer was not responding well when I tried to install a driver for my webcam. The error message said that I should try uninstalling some recently installed programs. So I did. There were some that were recently installed but I didn't really known what they were. Since they were recently installed, I didn't think they were necessary. Ever since last night, my computer has been spiking up and down in CPU usage and I don't know what to do. I am not sure if it has to do with the recently uninstalled programs. If so? I don't know which ones I uninstalled to fix the problem. What can I do? Please help!!!!

Please give us some helpful information..
Which model computer is this?
Which Windows does it run?
Which programs are you talking about?
When you give us an error message, quote it precisely on a line all by itself. Paraphrasing doesn't help. We don't care what the message means. We want just the string of characters. Spelling counts.

Beachballing and extreme GUI latency with low CPU usage

I generally only have two applications open. iTunes 11 playing MP3s of about 128kbps, and latest Google Chrome with up to 4-5 tabs. Usually I have gmail open, Facebook, and maybe 1-2 sites such as YouTube or Slashdot. I don't have any servers running.
The CPU load is usually 90% idle. The system load hovers around 1.5 for some reason. Though at times it jumps up to 3.5 even though CPU remains at 90% idle. I read a ton of Facebook pages. After about 30-40 page loads, Chrome stops letting me scroll. I can still click in the address bar, so I know the whole system isn't frozen. I can change tasks via ALT-TAB, however, when I do that, it takes 10 seconds for it to switch to Terminal. When Termianl is finally shown, it jumps to 90% CPU for a few seconds, and updates 5 times in a row, quickly, like a stuttering video, and then it is normal. If I activate Expose by moving the mouse to the bottom left corner, it shows the Dock right away, but then it just sits there frozen for 15 seconds, and then it shows the windows and whatnot. If I switch to the Finder and click on an icon, it doesn't do anything. I then click on another icon. Nothing. I then try to draw a bounding square on the empty desktop. Nothing. Then after about 30 seconds of being frozen, the system does EVERYTHING I did in a quick hurry. It selects the first icon, the second, draws a square, selects another icon.. etc. It seems to be queueing all my actions but not responding to them immediately. If I try to delete a file, the beachball shows up, and then after about 30 seconds it shows a progress bar, even for a tiny little text file, the progress bar takes 5 seconds, and then it removes it from the desktop. If I press Mac-T to open a new tab in Chrome, I get a beachball and it takes up to a full minute before the new tab shows up!
While all of this is happening I've been monitoring my system with top, the CPU keeps at 90% idle! And the load is usually below 2.0! I have a Core 2 Duo 2.1 gHz MacBook 13" with 2GB of RAM, and there's about 25 GB free on the main disk. There is also an external firewire drive connected. Every 5 minutes the Mac OS wakes up the drive from sleep even though I'm not using it, and while the drive is starting up the whole system freezes for 5-10 seconds again!!
What the **** kinda joke of an operating system is this?!?!!? I thought Macs were multitasking and everything! I'm seriously concerned.... I"ve never had these problems in Windows, and never had these problems in Linux. ***?!!!?! I can't use more than 5 tabs in Chrome either. It's way too slow. And most videos on YouTube I can't watch unless I lower to 340p or 240p, otherwise they freeze and stuff. Even though I have enough bandwdith.. The system can't handle the video. It's so frustrating. Oh and one more thing. While scrolling through pages on Facebook, iTunes pauses at random points as if it can't handle the scrolling.... ***??!?!?!
Please help me!!!

Hello? Does anyone from Adobe know why this is happening?
I understand why frames would be dropped if you set high
quality and your CPU can't encode in real time however the 30% cpu
usage I am getting while encoding isn't indicating to me I have a
cpu issue.
Also as a note when I change the quality settings at no point
can I get my CPU to actually get busy enough where I think frames
should be dropping.
Another side question. Is FME mult-threaded? We all know dual
cores are popular now. Also when I say 30% if its a single threaded
app, that would mean 100% = 2 cores, 50% = 1 core, so 30% of of
that 100% would be all on one core if its a single threaded
application.
This would mean perhaps the utilization is higher than
expected and frames are dropping perhaps.
Any insight would be great.
Thanks and take care.

Stuck with 50% cpu usage

I created a new thread for this problem because it has no relation to my first but does have similar symptoms.
Ok, every time I play a dvd audio disc the cpu spikes constantly to 61% then at some point it will keep 50% usage active despite not playing the dvd audio disc anymore(system is idle). By this time audio is puking anyway.
This also happens when I work on something that keeps exceeding the 50% cpu usage. At some point the 50% gets stuck and everything slows down and have to reboot.
At first I thought it was the soundcard now I suspect it is something else, since even in graphic applications it happens.

Performance is not really the issue. Since it is fast until it gets hit by the 50% bug.
I would have considered the interfaces too but that was with the older 50% problem. Problems with PATA/SATA/SCSI usually mean slow downs in transfer speeds and scratch disks. Getting stuck at 50% cpu usage seems like a bug.
Most people might not even encounter this problem unless the play dvd audio disks or use apps that peaks often.
I'm still worried with win2000 sp4. There has been issues with it.

Constant SBBOD with high cpu usage

Hi
since a couple of days ago I constantly get the SBBOD (spinning beach ball of death) on a Mac mini 2011 with Lion 10.7.3.
The system hangs up completely and the only this I can do is click around and move the windows but the clicks don't do anything and at some point after that everything just stops responding.
At this point I'm forced to do a hard reboot (power switch).
After that the system works for a while and then gets the SBBOD again.
During the SBBOD I can see syslog hogging all my cpu usage in activity monitor, but when I try to kill it or click into activity monitor the programm doesn't respond.
I guessed that something else was spaming syslogd with messages but after the hard reboot I don't see anything in console.
Since then I tried almost everything.
- hardware test, the short and long one -> nothing found
- repairing hard drive and permissions -> didn't help
- S.M.A.R.T says verified
- PRAM and NVRAM reset
- logged into guest account and started nothing -> SSBOD after ~hour
- started into save mode and left the comp running -> SSBOD after ~hour
- reformated(not zeroed) and reinstalled Lion(not from a backup) -> SSBOD after ~hour
Currently I'm trying to disable syslogd to see if some other process hogs all my cpu load instead of it.
I really hope one of you can help me, this thing is driving me nuts :/

Repairing the permissions of a home folder in Lion is a complicated procedure. I don’t know of a simpler one that always works.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy – do not type – the following line into the Terminal window, then press return:
chmod -R -N ~
The command will take a noticeable amount of time to run. When a new line ending in a dollar sign ($) appears below what you entered, it’s done. You may see a few error messages about an “invalid argument” while the command is running. You can ignore those. If you get an error message with the words “Permission denied,” enter this:
sudo !!
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
Next, boot from your recovery partition by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the recovery desktop appears, select Utilities ▹ Terminal from the menu bar.
In the Terminal window, enter “resetpassword” (without the quotes) and press return. A Reset Password window opens.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.

Macbook Pro Extremely hot with NO cpu usage

I have a Macbook pro 15" (Mid-2010). Recently my mac is running extremly hot specially when connected to the AC power.
I'm using iStat Pro to monitor sensors, and while charging sometimes CPU reaches 101 degrees celsius. When I detach the power cord, it stays at about 80-85 degrees. My cpu usage is normal, about 1-4%. All the bottom of my mac feels hot, specially under the CPU, but the middle parts too. Fans are also working with highest speed.
Is it a known hardware problem?
Another problem which I've had around the same time, I use "Hardware Growler" to check for usb connections. When I connect a USB flash disk, sometimes it shows a lot of connections and disconnections for Keyboard, Trackpad, IR Remote and stuff. Pushing the usb around doesn't show the same symptom, so it's not a broken board or connector or something.
Have you seen a similar problem? What can I do?

I've solved my problem by resetting PRAM and SMC. I'm writing my solution here so others can try it if they have the same problems.
To reset PRAM, follow instructions in this link: http://support.apple.com/kb/ht1379
and to reset SMC, follow this link: http://support.apple.com/kb/ht3964
I think my problem started when I upgraded Parallels Desktop to version 7 (from version 6). I'm not sure if it was the cause, but some kernel extension in parallels could've corrupted SMC and/or PRAM.
