CPU usage while rendering previews

Hi all,
I find it strange that when I render 1:1 previews for raw images from Nikon D800, my overclocked Core i7 3770K @ 4.5GHz is used anywhere from 22%-50% thus completing the render task slower than it really could.
Is it a known issue?
Is the a 'hotfix' for forcing LR4.3 utilizing the full potential of my CPU?
Is it like this for everyone?
I'm using Windows 7 64bit with 16GB RAM.
Thanks,
Gil.

No, I don't believe it works that way. When you select an image in Library, all that is loaded into RAM are any existing previews, not the image data. When you then ask Lightroom to create 1:1 previews, it will generate this from the actual image data.....hence the I/O activity reading this data, then the CPU activity rendering the preview, plus of course I/O activity writing the preview back to disk (as well as ACR cache entries if they don't already exist). On my much less powerful i7-930 system, this is the how the Task Manager looks when rendering 1:1 previews:
With a more powerful CPU, it wouldn't surprise me to see the spikes a little lower. The key question is how long does it take to render each preview for your D800 files?

Skype 4.2.0.11 has abnormally high CPU usage while...

Skype 4.2.0.11 has abnormally high CPU usage while idle.
I can't get my laptop under 70 degrees celsius unless I cpulimit or quit skype, and cpulimiting it actually makes it completely unresponsive, as if some other thread is constantly generating a lot of work and taking priority over the UI thread.
What the heck is skype doing? (And why do any of its threads need nice -10?) It takes up more CPU time than pulseaudio, truecrypt, and deluged combined.
Its CPU usage is constantly between 5 and 50 percent*, it's absolutely horrible.
*While idle. I'm unable to make calls.
I know this is expected from a linux user, but for all I know, Skype is malware. It's not open-source, so I can't find out for myself, and there are no open-source alternatives so the frankly shameful amount of bugs I encounter in Skype will never be fixed.
There are several bugs I'd love to be fixed in Skype, but first, PLEASE, optimize your code. It's absolutely horriffic at the moment.

Attached are statistics from my desktop over approximately a 24 hour period for the processes shown (other than firefox and adb).
Pulseaudio tops skype this time but that's because I've had music playing through mpd for a few hours. Skype uses more than 16 times the CPU that pidgin does, and almost double the RAM! RAM isn't shown in the screenshot but take my word for it. Bear in mind that I haven't taken (or made) any calls in this period of time, and pidgin has been signed into three different services and using encrypted chat.
I really wish that at least the protocol would be documented so someone could work around this, at the moment I don't think the guys writing skype realize just how unstable the linux port is. At least it's better than the Android port.
[Edit for those unfamiliar with linux processes: "TIME" is the cumulative time that the program has been scheduled for on any core, effectively making it a measure of total CPU usage for a given time period]

While we're aware of the issue, there's not much we can do about it. The modern security realities facing web browsers have made sandboxing a necessity.
There's a good explanation of what's happening here: http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html
Long story short, each video packet has to be passed from the browser to a medium-integrity broker process, then to the low-integrity flash player process for rendering. If an attacker manages to hijack the Flash Player thread, the process is low-integrity, which prevents the attacker from doing much with it. While it's not an absolute guarantee (nothing in security is), it raises the bar significantly for attackers.
The downside is that all of that extra message-passing consumes CPU cycles, especially if you're trying to fill an exceptionally large buffer as fast as possible. There's not a lot of opportunity to optimize this.
If you're fine with the risk, you can manually disable ProtectedMode on your machine. If you're only dealing with trusted sites, and you're not doing anything critical with the machine (work, banking, etc), then it's probably not a huge deal.
Ultimately, ProtectedMode is like a vaccine -- it's a herd-immunity thing. If the majority of people run it, exploits targeting machines without it are inconsistent and probably not worth pursuing when you look at the effort involved in developing an end-to-end exploit. If a large number of people disable it, it becomes economically attractive for people building botnets, and you'll have a problem if you're not using it.
To disable Protected Mode, add the following line to your mms.cfg file located in:
Windows 32bit: C:\windows\system32\macromed\flash
Windows 64bit: C:\windows\syswow64\macromed\flash
ProtectedMode=0
If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)
Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.
To re-enable Protected Mode, simply remove the line from the mms.cfg file.

Firefox is eating up between 90% CPU usage to %230 CPU usage, while on a text-only page. I've tried many of the fixits. They didn't work. What can I do?

I've cleared cookies multiple times
I've emptied the cache
I cleared my download history, and a majority of my browsing history
I've tried having hardware acceleration for both flash and firefox on and off
I turned off all my apps and plugins and when that did nothing I turned back on the ones I need. I never had a lot of apps to begin with. only a max of 5. I had quite a few plugins, but i disabled all but quicktime, flash, and silverlight. I have those three set on "ask to activate" so none are "always active" anymore.
I also tried a couple things from the FAQ and forums here about changing a few settings in the "about:config" setup.
A few of the above things initially worked, but after a day or two it'd be back to sucking up my CPU and memory. I would then try the same thing again, and this second time there would be no improvement.
The real memory will fluctuate between 200 MB and 1.7 GB, and has done so for quite a while.
Even after I've left streaming sites, and sites with lots of images, and I'm not downloading anything, the memory and the CPU will still do that. I only have a handful of tabs open at a timeusually, and all of them are mostly text. I'll quit and reopen firefox, which will initially bring the memory and CPU usage down, but it inevitably climbs up quite quickly, regardless of my tab usage. It'll be the same if I'm playing a flash game or scrolling through blogs.
I never had any of these problems with Firefox 23, and my internet usage habits haven't changed at all. I had some of this slowness a few times with version 24, but nowhere near as bad as this, or as constant. Almost everyday I end up googling for other ways to speed things up. Everything I do never slowed down Firefox on earlier versions.
I've tried all my usual tasks on Safari which will never climb above 30-40 MB of memory, even on netflix streaming, or flash games, and the CPU will average around 8 and 11%.

i'm also having major CPU problems w/ FF 29.0.1. when i restart the app it calms down again but after loading tabs it steadily climbs up to 100% after not too long. i have checked out the 2 CPU links/articles above and do all the basic troubleshooting and tips, but with all the FF tools & add-ons isn't there some sort of CPU monitor that has the ability to display which extensions/scripts are hogging the CPU? Activity Monitor on Mac just shows the total used by the app. it's impossible in my case to efficiently disable dozens of add-ons & scripts, restart, and test each one by one b/c it can take several hrs before the CPU starts to spike high again. i have no time for this.
thanks

LIRC - 100% cpu usage while pressing a button

Hi all.
I'm having some problems with latest lirc versions. It just uses 100% of my cpu while I press any key on the remote. For example, with xbmc, pressing a remote control button makes a one second video lag and frame dropping due to high cpu usage...
I'm using latest kernel and lirc in testing repo
Pinnacle pctv remote (and receiver, rs232 ou ttyS0).
I can't follow the wiki since kernel 2.6.25 (maybe), if i do modprobe lirc_serial (and before a setserial uart none), on irw, nothing happens. -> this used to work before.
I've edited /etc/conf.d/lircd in order to make this remote to work. I don't need anymore to load lirc_serial and remote works... but uses ALL CPU resources.
Solutions? Anyone with same problem?
Thanks friends:D

IMac Air High CPU Usage while Idle / Kernel Issues

Hello,
I am attempting to repair an MacBook Air that a customer spilled a small amount of orange juice into. I have completely taken the unit apart and thoroughly cleaned the motherboard and all components. There doesn't appear to be any physical damage done from the liquid. The problem is that the customer claims that since the spill happened the computer runs "very slow" and the CPU usage is very high even while completely idle (Bounces between 60%-80%). Being versed primarily in Windows PC Repair I am looking to post some diagnostic logs on here and maybe get some help from someone who knows what they are looking at. The customer took the machine to the Apple Store and they told them it had a "kernel problem" and would need a new Logic Board. Any help would be greatly appreciated, I just need to know what diagnostic reports I need to post to get this ball rolling... Thank you for your time.

CPU usage while running Bex report

Hello,
Sometimes, when I run a Bex report with many lines the computer CPU Usage is 100% (=full ) for a long time. In some cases i need to do restart again for the computer.
In the WAD it doesnt happened...
Did anybody have the same problem? Is there a way to reduce the CPU usage?
Please Advice,
Amir

Amir,
This is "normal" behaviour in Bex with query's which return very long lists. The client computer already received all data, but is formatting the layout.
Solutions:
1) a faster pc with enough memory (512 mb) and win200 or >.
2) a query with less return rows.
The reason that in wad (web reporting) this is not experienced is because the formatting (rendering html) from the result table is done within the WAS (application server, which is hopefully faster then your PC...). Your browser only receives the html page..no exotic hardware needed for that..
Any questions left: please ask; if you're satisfied please grant with rewards.
Kind regards Patrick Rieken.

High CPU usage while display is asleep

This is a strange one, and I've noticed it on multiple distros, and Arch is no different. When my system is sitting idle with the screen on my CPU usage hovers around 5%, which I would consider to be perfectly normal. However, when the display goes to sleep (no screen saver, just DPMS sleep) the CPU jumps up to about 25% and stays there until I bump the mouse (or do whatever to wake the system up), and then it will drop back down to the normal 5% CPU usage.
I had always thought it had something to do with Firefox, but I had Firefox closed while I was away at work today, and yet when I come home and wake my computer up my CPU usage graph shows that it's been at a solid 25% all day long.
Anyone have any ideas what this might be, or recommend a way to hunt down exactly what process is eating my CPU cycles while the display is off?
Thanks a lot, this has been puzzling me for some time now.
EDIT: I should add that I am running KDE, and have been on the other distros as well (to the best of my recollection). After realizing this it seems like this thread may be better suited for the Applications & DE forum, but I'm not sure... it could very well be something to do with the kernel or something to do with power saving. Please move if you see fit.

The CPU usage is not accounted for in the system monitor app. There's roughly 4% usage accounted for, yet there's a total of 29% being used.
The script doesn't seem to find anything either. High idle CPU usage kicks in maybe 3/4 of the way through, but the output doesn't seem to change from the beginning at all.

CPU Usage % While Editing Video

We get quite a few questions on why CPU usage is below 100% in some operations. This applies to both PrE and PrPro. Here is a THREAD (on PrPro, so there are some Pro-specific comments involved in the thread), and Harm Millaard has distilled the possibilities nicely in Reply #1.
Note: there is a link to the PrPro CS5 Benchmark. The site, and benchmark files and tests are not available for PrE, but when comparing hardware, the spreadsheet of the performance data from users' configurations, can tell one a lot, even if they are running PrE, and cannot actually participate in the benchmarking - the data in that spreadsheet is still VERY useful, when looking at various computer configurations.
Good luck, and hope that this helps others,

1) Why video rendering is taking about 3h to render 2.2Gb wma file to make it HD 720p 29.97 with H.264 codec? CPU is loaded only 16-20%, have alot of RAM. Ou and tried both OpenCL and system only renderer no change in time needed or CPU load.
Because of the source material and the hardware. Wrong CPU, video card an not enough memory.
2) Does Mercury Playback Engine GPU Acceleration (OpenCL) means GPU usage mostly and system only - CPU usage?
Exporting is CPU based, the Radeon does not help at all. Tweakers Page - Exporting Style
3) Why is so low CPU usage I thought that doing something big like video editing CPU should be fully loaded..., but here I see that it as I said is using only 16-20% and 2-3 cores aren't even in use.
Again because of the source material / codec and the hardware. Typical of ill-threaded codecs and the CPU.
4) Is it ok for a recorded game video to be big like 2-5Gb after rendering in HD format, because I think if films 44 min HD quality are 350-400MB than game videos should be about the same.
44 min. of HD material can never be 350-400 MB of decent quality. 44 min of SD material (DVD) is already over 3 GB for decent quality. For HD, even on YouTube, count on at least 4-5 GB for 44 minutes or more.
5) Maybe there is a better video capture app than Fraps, Overwolf, raptr GVR (well looked fine but I couldn't edit the video, Adobe element showed black screen and played audio) so that I could easelly edit it with adobe apps.
You can't capture with any of the software you mention, Capture is only possible with tape cased cameras over firewire.
Your AMD 8-core CPU is not suited for video editing, it is even slower than a 4-core Intel, because of the lacking SSE support. See Tweakers Page - What kind of PC to use? Your Radeon is pretty slow for editing, Tweakers Page - What video card to use? and the amount of memory is limited.

Mac Pro CPU temperature while rendering

Hey there, I just recently got myself a Mac Pro 2009 with a stock CPU - quad 2.66. While rendering, my CPU temperature goes up to 71C/160F and fans are on their defaults. Im just wondering if this temperature is OK for fans to not kick in, or I should reset something? Thank you

By seeing all the thermal sensor readings, and fans, sometimes people have found an issue where the readings were not right - sensor was getting wrong reading or none -
Laptop like MacBook Pro can often have their fans running much harder to cool and deal with heat.
Those new Haswell chips are suppose to run even hotten, they may be providing Intel 4600 integrated graphics as well as cpu functions, PCIe and USB3 as well as memory controller. They are powerful and efficient - and you will see cpu spikes in utilization AND corresponding changes in temps. \
Same on Mac Pro but not as extreme. Opening apps and files can show 10*C jumps for 1/2 second.
If you are going to render, then sure do what helps the system stay cooler and in a safe(r) temperature range. Newer components are helping companies save $$ on cooling and being able to run servers and even disk drives by 5*C warmer making a huge change. Think Google, Facebook or NSA having large factory flooors housing equipment needing to be kept in temperature controlled environments.

CPU usage while generating text output from reports

hi
while we attempt to generate the text (delimited) output from reports and when the query fetches more than 1500 rows, the cpu usage stays around 100% for long time paralysing the operation...
we faced the problem when we attempted to generate text output for around 10000 records.
any suggestions?

You can burst with eText and I have done it
successfully.
I don't believe pagebreaks are an option in eText and
I don't think it makes sense either since your
generating a flat-file and not a customer or internal
facing document. Does that make sense?
Also, if you would like you can use the
BIPublisherIDE, this code can be converted pretty
easily to handle jcp. There is a an oa framework
version I have developed but I haven't posted on my
blog yet. I plan on adding a bolt on for java
concurrent programs soon. it's really pretty simple
just haven't had the time.

Thanks Ike for your reply.
I agree with your points on TXT files, but in our case,the reports are generated in TXT format for the customer so we are looking for the above mentioned features.
I have gone through BIP IDE and its a wonderful small utility which eases the task of BIP development.
As I mentioned in my original post that we are currently processing the generated TXT report using a custom util. in JAVA to get the desired output in TXT again.
I assume thats not what a JCP would do,so I am looking to explore that too.
As I understand the process for report generation is
1. Generate XSL from eTEXT template.
2. Get the XML data from DB using XDO
3. Apply XSL on XML to get the required template.
If we are looking to achieve some customizations then we need to have the XSL generated with those customizations.
In this case, where do we plug in the JCP to alter XSL or am I missing something.

High CPU usage while running a java program

Hi All,
Need some input regarding one issue I am facing.
I have written a simple JAVA program that lists down all the files and directories under one root directory and then copies/replicates them to another location. I am using java.nio package for copying the files. When I am running the program, everything is working fine. But the process is eating up all the memories and the CPU usage is reaching upto 95-100%. So the whole system is getting slowed down.
Is there any way I can control the CPU usage? I want this program to run silently without affecting the system or its performance.

Hi,
Below is the code snippets I am using,
For listing down files/directories:
        static void Process(File aFile, File aFile2) {
          spc_count++;
          String spcs = "";
          for (int i = 0; i < spc_count; i++)
          spcs += "-";
          if(aFile.isFile()) {
               System.out.println(spcs + "[FILE] " + aFile2.toURI().relativize(aFile.toURI()).getPath());
               String newFile = dest + aFile2.toURI().relativize(aFile.toURI()).getPath();
               File nf = new File(newFile);
               try {
                    FileCopy.copyFile(aFile ,nf);
               } catch (IOException ex) {
                    Logger.getLogger(ContentList.class.getName()).log(Level.SEVERE, null, ex);
          } else if (aFile.isDirectory()) {
               //System.out.println(spcs + "[DIR] " + aFile2.toURI().relativize(aFile.toURI()).getPath());
               String newDir = dest + aFile2.toURI().relativize(aFile.toURI()).getPath();
               File nd = new File(newDir);
               nd.mkdir();
               File[] listOfFiles = aFile.listFiles();
               if(listOfFiles!=null) {
                    for (int i = 0; i < listOfFiles.length; i++)
                         Process(listOfFiles, aFile2);
               } else {
                    System.out.println(spcs + " [ACCESS DENIED]");
          spc_count--;
for copying files/directories:public static void copyFile(File in, File out)
throws IOException {
FileChannel inChannel = new
FileInputStream(in).getChannel();
FileChannel outChannel = new
FileOutputStream(out).getChannel();
try {
inChannel.transferTo(0, inChannel.size(),
outChannel);
catch (IOException e) {
throw e;
finally {
if (inChannel != null) inChannel.close();
if (outChannel != null) outChannel.close();
Please let me know if any better approach is there. But as I already said, currently it's eating up the whole memory.
Thanks in advance.

(note: after my upgrade, i got a black screen on booting up. i had to use the 'nomodeset' option to disable kms. this probably isn't related, but i thought it might be worth mentioning.)
any ideas?

you're right. i forgot that i made some changes to my igoogle page. the chat function is the culprit. adding it causes the spike. i've reported the problem. thanks for the help!

How can i reduce CPU usage while playing video?

Hi,
I have recently finished and then published a project to my desktop which is a video jukebox application. The application plays music videos in a large popup window upon a button click. The problem i have is that when the video is not playing the CPU usage on my windows machine runs at about 15% on average, however once the video is playing in the popup the CPU usage jumps to almost 90-100%.
I have seen some of the developements introduced in Flash 10.2 in regard to Stage Video and was wondering if this could maybe fix my problem. At present my application is running on AIR 1.5 with Flash Player 9. If I simply install the latest versions of AIR and Flash Player and try running my published project again will this be enough to improve the video performance? Or do I need to change the settings of my project within Flex Builder so that it uses the latest version Flash?
Any advise would be great.
Thanks
Adam

StageVideo is still not available for AIR and until then it appears nothing can be done about this problem.

Cpu usage while not doing anything

hi all
i have the latest update to leopard. and just now, without using big apps like photoshop or such, the cpu usage is almost at full tilt as if i were using a big app
the fan is on all the time...
help

Look under activity monitor and choose all processes to see what is eating up your cpu processes. There is usually a rogue process that is causing this. Kill it and it should stop the fans running so hard.
