LR uses 10% cpu even when idle

I noticed that LR 3.3 consumes 10% cpu all the time even when it sits in the background (and I'm working within an other application and I have NOT started any batch)?!
After putting LR in the foreground (as active application) it consumes less then 5%?!
What is it doing??
Are there some settings to reduce/switch of background tasks?
(I already switched off memorycard detection for import, and XMP autosave)

It's really annoying that LR misses a lot of really tiny things that Adobe developers could implement them alltogether in only a some days. But no - you have to install lots of plugins, which lack of the poor LR api.
Well, the SDK is actually pretty complete, and quite powerful. Lr is a heavily threaded application, and this is exposed to some extent by the SDK. For plugin authors, this is really nice. It offers a way to make very powerful additions to Lr that don't belong in the core product, but behave as if they are.
But it means that a poorly written plugin can soak up a fair amount of resources. Note, however, that a plugin cannot totally steal all resources. There is a governor on that, so the worst you will see is this sort of problem -- annoying, maybe, but not disasterous.
And remember that the vast majority of plugins will use the tasks and threads handed to it from the application, and will never exhibit these symptoms. It is only some sorts of plugins written in a specific manner that would ever impact overall application execution profile. So, you could install many plugins and never see a change in behaviour whether 1 or 10 were enabled. But install and run one that cycles hard on blocking activity and you will see this problem.
There is always a trade-off. Plugins make the application very flexible, but with this flexibility comes some risk. There is no perfect solution and there never will be. (Adobe could never implement all plugin behaviour everyone would want as first-class features in the core product -- this is impossible.)

Why is itunes using 94-97% of my cpu, even when idle?

i am running a 2.53ghz macbook pro with snow leopard, and whenever i have itunes running, it hovers around 94-97% cpu usage, even when idle. Whats wrong?

Try initially deleting the /Home/Library/Preferences/org.mozilla.firefox.plist file and the /Home/Library/Caches/Firefox/ folder. If you have installed any Firefox extensions/plug-ins be sure to upgrade them to the latest versions or uninstall them.

SpeedGrade Pins CPU even when IDLE

Start up SpeeGrade, all is normal.
Add a clip to the timeline, the CPU usage jumps to 200% (both cores) and stays there forever, until I delete the timeline.
Any ideas?

Firefox uses up 10% of processor even when idle. Why?

Firefox 3.6 uses at 10% of processor power even when idle, parked on Google. I have McAfee, which uses 5% to 10% on top.
Firefox loses keystrokes. It gobbles up a lot of memory very fast (did not do this before). After about 2-3 hours of surfing, it uses up 6-% to 70% of processor power to the point I have to reboot.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I refered the metalink document id: [ID 761960.1]
Database Instance Using Swap Space When There is Plenty of Free RAM metalink note [ID 761960.1]
and tried the disabling the sga_max_size and memory_max_target and memory target with all different combination but no use.
We have one more box where same setup was configured in solaris platform but there the above memory parameters are not disabled but it is not using swap space it takes memry only from physical RAM
Can any one throw some lights on this issue. It wopuld be great if I come to know where the exact problem
Thanks in advance

Hi,
I didn't say I am not using 11gr2 memory parameters I am using all the automatic memory parameters but the thinks is as per the metalink note I tried by disabling the automatic memory parameters. but that didn't help me in preventing unnecessary swap usage. So I reverted. now it is using automatic memory parameters.
so What is the solution for this?

Xorg's CPU usage when idle

Hello archers,
Considering I don't have a wooden laptop at all, is it normal that my Xorg uses in average 15% of one of my CPUs even when idle ? (I would be quite surprised to get a positive answer...)
Is there any way to reduce this number ? Because I find it bothering to hear my fan running whereas I'm doing hardly anything with my computer.
Thanks for all your answers.

I have Xorg using 8% of CPU (frequency is approximately 2GHz) when "uTorrent" under "wine" is running and 0% otherwise. Do not know why.
Observe it when Xorg is running with "xterm" only.

High cpu usage when idle / x230

Hi all,
I have an i5 x230, win8 pro installed on a crucial m4 msata ssd, 16gb of ram. I lately noticed a sharp drop in battery life. I believe this is due by high cpu utilization when idle, which I see from task manager, and shows the System process hovering above 30% cpu utilization. This goes down when I restart, but comes up again after a while, possibly when coming back from sleep.
Does anyone have any idea about this? I tried to search the knowledge base a bit, but nothing came up.
Thanks!
Solved!
Go to Solution.

Indeed it was risdxc64.sys; I used process explorer to find out. I uninstalled the win 8 driver, and installed back the win 7 driver, and CPU usage is normalized.
Thanks for pointing in the right direction!

Observation: SAP uses swap space even when OS has available unused memory

Hi Folks,
   It is my understanding that any memory not used by the Linux OS itself or the SAP application is available for Linux to use for I/O buffers and file caching. When the SAP application requires more memory I would expect Linux to take memory away from itself (release I/O buffer and/or file caching memory).
   We have observed that SAP uses swap space even when there is memory available. Is there some feature in SAP kernel or some ABAP construct that causes SAP to prefer swap space over available memory? Or maybe there is a Linux kernel setting that influences SAP's use of swapping.
Regards,
Zaz

Hi Mike
You did not mention which distribution you have. Under SLES there is is a parameter called SWAPPINESS, which controls the buffering/swapping.
cat /proc/sys/vm/swappiness
If you don't already know, you can see the memory usage with the free command.
root # free -m
             total       used       free     shared    buffers     cached
Mem:          7987       7901         85          0        364       4262
-/+ buffers/cache:       3274       4712
Swap:        15999          0      15999
As far as i know, in this example 3274 is memory used by SAP and other processes and 4712 is cache. Please correct me if i am wrong.
Regards
Michael
Edit: a low swappines, for example 10 means to reduce cache first, a high swappiness (example 100) means page out processes first

[Solved] High load average even when idle after update

Hello arch fellows!
I have a Dell Inspiron N4110 intel i5 4gb ram. I think it is a decent laptop and should run Arch Linux pretty well, right? Well, it does until I run 'pacman -Syu'. After the update, the load average gets over 1.00 even when idle. It hardly gets under 0.40. Before updating, the average is under 0.10 most times. The command top doesn't show me anything. All the processes are practically 0%. It seems to me the problem would be the kernel, am I right? But I tried the fallback option when booting but it is the same.
Does anybody have an idea of what could be the problem? I appreciate any help.

Thanks for the reply. It was really a kernel problem. I downgraded it to an older version and it looks normal now

Continual HD activity, high CPU usage when idle

I got my first notebook, a Compaq V2000, a few weeks ago and have Arch set up pretty well on it but I have a few issues. Even when the machine is sitting idle it sounds like the HD is doing a read (or whatever) about every 5 seconds. This only starts after I log into Gnome and stops if I log out.
I tried a couple of things with hdparm:
If I try 'hdparm -y /dev/hda' the drive goes to standby but immediately spins up again.
'hdparm -B 255 /dev/hda' disables APM and stops the cyclic behavior. This would seem to be good but during the 5 second cycle the drive alternates between quiet and noisy and this leaves it in the noisy state.
I tried to determine what might be causing all this disk activity so I edited lilo.conf to remove "acpi=on apm=off" from the "append=" line and in rc.conf I put a ! in front of all modules and daemons and rebooted. I removed the applets from task bar. No change.
I ran top to see if I could tell what was accessing the HD but I'm not knowledgable enough to make much sense of it. I did notice that on my notebook the top summary shows:
CPU: ~30% user, ~10% system, ~60% idle with 'wait' bouncing between 0 and 5%
On my main computer, also running Arch/Gnome, I get
CPU: ~2% user, ~1% system, ~97% idle with 'wait' solid at 0%
On the notebook, if I run hdparm -B 255 /dev/hda the CPU #'s for user and system remain high but the wait # drops to zero and stays there.
I don't think all this HD activity could be good for my machine, and I know I find it very annoying. If anyone could help me stop all the HD accesses and understand the high CPU usage I would appreciate it.

I loaded lsof and frankly it scared me. It listed what looked like a couple hundred files and I didn't know exactly how to use that information.
Then I tried laptop-mode-tools. The man pages didn't sound too promising since it uses, among other things, hdparm, which I already tried with mixed results. I gave it a try anyway and right out of the box, with no configuration, it worked. HD access when idle dropped to essentially none, the drive spins down and the cooling fan runs much less frequently.
So far all I have changed in the config file are the HD idle timeouts. The default of 5 seconds was starting and stopping the HD too often so I changed that to 20 seconds for now.
Whatever laptop-mode did to stop the 5-second HD accesses the effect persists even if I run 'laptop_mode stop' and '/etc/rc.d/laptop-mode stop'. When I get the time I should be able to use 'laptop_mode status' and laptop-mode.conf settings to determine exactly what the magic bullet was.
Thanks, lucke. I never would have tried laptop-mode on my own because I thought it only duplicated functionality that I already had with hdparm and powernowd.

High CPU Usage when Idle

Hello Crew!!!
I have been using a ThinkPad Z60t, running the OS WinXP Pro that came bundled with the Thinkvantage Software. I have had no problems with my computer for the two years I have been using it. I use it as much if not more then a traditional desktop, covering all aspects of my life, from business to gaming (although it is not a gaming comp, it does me fine). Recently, within the last week or so, I noticed a huge lag-like spike every minute or less, including when the system is idle and isn't playing anything. I ran McAfee as well as AdAware and found no issues out of the ordinary. After reading a few forumn posts, on other websites, I ran a processes check, with Microsoft based software "Sysinternals" and found that over 50-80% of my processor was being used by Deffered Procedure Calls (DPC's) and Hardware interrupts. I chose to reinitialize my entire system, back to factory settings, wiped it all. Guess what it is still doing it!!!!
I have completely updated my OS, and other forumns suggest that there is a hardware issue, or intermittent signal with the CPU or Motherboard, what can I do to test this theory or to find solutions, please help me!!!!!

It is not "normal" and cannot be "normal". Programmers like that must be fired immediately.
It's like iTunes - scroll cover flow fast enough, and you can get memory usage up to 1GB (!!?) which is even not fully returned after you stop scrolling.
And those people are making jokes about Windows? Yes, it is ugly but when they have blunders like this, at least they correct them. Just returned from the shop, wanted to buy 27" iMac. 3.06GHz model was running Parallels with Vista, processor usage continuously like 3-5%. iMac was cooking - if I put my face 0.5m from the screen, I could feel the heat!
I don't know about iTunes... some of the recent Mac apps (Safari, iTunes) are so slow/inefficient I stay away from them. However, Logic's CPU use when idle is completely normal for a "real time" application that starts approx 20 threads minimum. All DAW application do this to some extent, some more than Logic.
What's not normal is how much heat the new Macbook, MBP and iMacs are generating, the folks over on the Macbook forums are starting to see heat related failures.
As a side note, Windows 7 is much more efficient than Windows XP_Professional, that's saying something as XP is a good real time DAW OS. After Vista I didn't expect much but Win_7 is a nice OS.

20% CPU load when idle, 27" iMac corei7 2,8Ghz

Hi every body
When I'm running Windows 7 Professional 64bit on Boot Camp 3.1, the system uses 20% CPU when idle.
I've tried to figure out what's causing the system load, and so far no luck. The task manager show these processes using CPU:
SYSTEM : 9%
DCPs : 6%
csrss.exe: 3%
Interrupts: 4%
The system is a fresh install, no programs installed, except Boot Camp. Even before I installed the Boot Camp drivers the CPU load was 20% when idle.
Has anyone had the same problem? And have you found a solution?

The system is a fresh install, no programs installed, except Boot Camp. Even before I installed the Boot Camp drivers the CPU load was 20% when idle.
If you have not booted into Windows, anything that happens under Mac OS X is something unrelated. In this case, it may be Spotlight indexing connected drives or some other background maintenance process. Leave the iMac running for a while and check to see if the CPU load is still 20%.

Xcode using 100% cpu even with no projects open: Solution

Symptom:
I had a very strange problem with Xcode 3.2.1 on Snow Leopard 10.6.2. As soon as I opened a project, Xcode would start using 100% of the cpu. It would continue doing this even after I closed ALL open projects. Xcode was using 100% cpu (200% actually) even while idle! Xcode would also often hang. I tried deleting Xcode and reinstalling twice. That didn't help. After much searching and trial and error I discovered the problem and the solution:
Problem:
I had an SCM entry defined from a previous remote site session in the SCM tab of the Xcode preferences. This site was no longer responding to requests, and apparently Xcode was continually trying to connect. Apparently the preferences were saved across the uninstall even though I used the shell script to uninstall all the developer tools.
Solution:
Delete the unavailable repository from the SCM tab in Xcode preferences.
I hope this saves someone the aggravation this problem has caused me.

Qosmio F50-10Z - fan cycling on and off even when idle

My f50 is constantly turning the fan on and off every couple of minutes, even when the machine is idle and has not run any applications.
SpeedFan shows that the GPU is cycling constantly between 55 and 65 degrees C even when there are no apps running (e.g. just after booting) - the fan kicks in at 65, turns off at 55 and then slowly heats up again. The fan noise is noticeable (I don't think it is going full speed, though), and it is a bit abrupt and annoying to be happening constantly and doesn't seem like normal behavior. Core 1 and 2 on Speedfan are cycling between 40 and 45 C
Outside temperature is 20 degrees, so the environment is unlikely to be a factor. I've air blasted the fan for dust (as much as you can seeing as the f50 isn't built to be taken apart by a Home User), but even when the fan is running the output doesn't seem noticeably hot.
I'm am only running toshiba drivers from the website (currently 7.15.11.7590)
My main concern is that this will negatively impact the life of the fan. Am I being overly picky or is there something I could be doing?
Thanks for any advice

Thanks for the reply Lars_3.
The notebook came with Windows Home Premium pre-installed - I haven't replaced the OS at all, though I have created a recovery disk at the urging of OS when I first booted it.
The BIOS is up-to-date as I use the Toshiba Tempro service (which again was pre-installed) and occasionally check with the website to make sure I haven't missed anything. I don't like the idea of installing drivers or anything else not released by Toshiba as I've seen people mentioning overheating shutdowns (at much higher temps) from using non-f50 drivers. I regularly keep the base elevated to enhance air circulation, and clean the intakes with compressed air, but it doesn't seem to make much difference.
Everything else works perfectly (and I'm a happy customer) except for the noise factor of the fan switching on every two minutes during even light use (not even 3d game use, which I assume would utilise the 3d card more and be expected to come with greater fan use).

Cluster Anomaly: WLS hogs CPU even when no clients

          I was just running a test and just need some comments on the following:
          I have the following hardware config:
          Browser -> Machine1(M1) -> Machine2(M2)
          M1=Solaris
          M2=NT Workstation
          .M1 runs WLS 5.1SP5 as webserver in proxy mode using
          "...weblogic.servlet.internal.HttpClusterServlet" with
          "...defaultServers=<M2>:...'
          .Basically just one machine in the WL cluster.
          .M2 runs WLS 5.1SP5.
          When I use the browser (on a 3rd machine) to hit a servlet on M2 via M1,
          everything is fine. I get the expected servlet response.
          However, when I hit the same servlet many times at a fast rate for about 10
          secs and then stop, I find that the CPU activity on M1 and M2 is about 90%
          and 50% respectively -- even AFTER I've stopped hitting the servlet. This
          unexplained CPU activity by WLS continues indefinitely. And I'm the only user
          on these machines and have verified that there are no other processes. I
          verified that it is WLS causing the CPU activity (using "top" on Solaris
          and "NT Task Manager" on NT).
          After I kill the WLS on M1, the CPU activity on M2 returns to zero.
          - What's going on?
          - What's WLS doing even when there are no requests hitting it?
          - Is this a bug?
          Seems to me that WLS goes into some sort of infinite loop communicating
          with machines in the cluster when it is stressed under the given config.
          The 2nd issue is: Why is the performance with a proxy so much
          worse than if I had hit the servlet directly on M2?
          I.e. Without the WLS proxy, I get, say 240 pages/sec.
          With the WLS proxy, I get only 60 pages/sec.
          Any clues?
          How else can I tune WLS to perform better aside from
          doing the stuff recommended in the tuning sections of
          the docs?
          Any insights will be most appreciated.
          Thanks.
