Firefox.exe* uses large amount of cpu 40-50%

My computer slows and task manager shows firefox.exe* very large cpu usage.

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

Syncserver.exe taking large amount of CPU process after iTunes closing

Hi,
OS system : Win 8.1 64 bit
itune release : 12.0.1.26
Antivirus software : Kaspersky internet security 2015 release: 15.01.415 (b)
After iTunes closing the syncserver.exe process will take a large amount of CPU Process.
The problem has begins after KIS 2015 installation.
I tried to apply a procedure finded on another forum : Windows 7 compatibility mode and run as administrator for distnoted.exe and syncserver.exe. The problem remaind.
Thank for your help

Hello~ Chrisrob94
My computer environment is
OS: Win 8.1 x64
Itunes: 12.0.1.26
Anti-Virus: KIS2015 15.00.463(b)
I has same your problem too. But I solved in the following way;
File Path1: C:\Program Files (x86)\Common Files\Apple\Apple Application Support\distnoted.exe
File Path2: C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\SyncServer.exe
this file [Right Click] and Properties. on the compatibility tab(click change setting for all users);;;
then check run this program in compatibility mode for: and select windows 7.
also check run this program as an administrator. click apply then ok
if already running syncserver, disnoted kill it. using windows task manager.
This seemed to fix the problem for me....Good luck to you!

New x301 - Taskmgr.exe uses "constant" amount of CPU. My t60 does not why?

When I click on "Start Task Manager" I notice that even with ALL programs closed, the only process to use CPU between 2% and 10% is the Task manager (taskmgr.exe).
I also have a t60 (xp pro sp3) and noticed that task manager users 0% CPU. I know its not absolute zero but not enough to count as 1% and does not kept using up CPU.
This is my first 64 bit system. It's 1.4 dual core with 4gb ram and 128gb solid state drive.
Why is taskmgr.exe using up so much CPU %? How can this be fixed?
Anyone else with an x301 or 64bit lenovo with this similar behavior?
Thanks

anyone?

Constantly getting messages Firefox is using large amounts (600,000+) CPU & sometimes for the plug-in,too. Solution?

When using Firefox, I now get messages from Norton, constantly, stating CPU usage is abnormally high (600,000+). I sometimes notice a plug-in container usage is also high on my Windows task manager. It's making my computer very slow. Any suggestions?

I think your 4GB of RAM could have something to do with it. 4GB is a pretty small amount and the minimum. Your system is really like a clogged vacuum and is not running to it's full potential. I would upgrade the RAM. My Macbook Pro is a Late 2011 2.2ghz i7 quad-core with 8GB RAM and fly's... After all, RAM is used to store files as you are using your system and when it uses up the 4GB writes those files to the HDD/SSD. The more RAM, the faster you'll be, because it will take a lot longer to fill up the RAM. I can put 16GB of RAM in my model, and plan on it. I also will be getting a SSD very soon and probably first.

Causes windows 7 desktop window manager (wdm.exe) to use large amounts of memory

Whenever I have Firefox4 open, it causes dwm.exe (Windows desktop manager) to use large amounts of RAM - It starts at about 100MB, quickly increasing to about 1GB over 20 seconds, then dropping back down to 100MB and so on. It does this continuously while Firefox4 is open, with the occasional "Your computer is running slow" message being shown by Windows.
Update: Only occurs when browser isn't on the primary display on a multi-monitor setup.

I had the exact same problem. DWM would use massive amount of memory when Firefox 4 was open on my secondary display, especially when scrolling with the mouse wheel. It would use so much that Windows 7 (8GB RAM) would turn off Aero. Going into Options>Advanced>General and unchecking "use hardware acceleration" fixed the issue. Of course now I can't take advantage of any hardware acceleration.

I Have the same problem, I switched off location services, maps in data, whatever else maps could be involved in nd then just last nite it chewed 100mb... I'm also on vodacom so I'm seeing a pattern here somehow. Siri was switched on however so I switched it off now nd will see what happens. but I'm gonna go into both apple and vodacom this afternoon because this must be sorted out its a serious issue we have on our hands and some uproar needs to be made against those responsible!

"Plugin Container" remains open, consuming large amounts of CPU power for nothing, even after Firefox is quit! It can only be killed from the Activity Monitor!

(I'm on a Mac.)

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

MSMPENG Requiring large amounts of CPU Time

<---Time
This is a picture of the CPU consumption on a multiprocessor cpu activity monitor on Win 7 SP1 running a Sandybridge Extreme. I know there was a problem during XP days. This has been going on for about an hour and one half. The system logical disk is about
125 GB and I had nothing running at the time. The activity shown was MSMPENG.EXE according to the task manager.
I am using Windows Defender and Malware Bytes as AV. I've been advised that it's ok to run them both. All disks on the system are SSDs. It's continuing in this state...... The green horizontal line is physical memory consumption which rather low.

App Store uses large amounts of data on startup?

Hi everyone. This might be a bit of an odd question, but in my search for where the heck all my data has gone, I've been doing some monitoring and noticed something that seemed pretty strange. When I start the App Store application on Mountain Lion, it uses at least 20MB of data, and normally a lot more - up to 30 or 40MB. This is just to launch the application. If you have an unlimited download quota, this will probably be of no interest to you, although it will affect startup speed I expect. Where I live, downloads are limited, so this is a problem. I wouldn't classify 40MB as really large, my quota for the month is 75GB, but it seems very excessive just to launch an app. Since I am routinely hitting my download limit I am looking to minimise wastage.
I guess I have one main question: Does anyone know whether it is possible to fix this, perhaps somehow in the preferences or way I use the app? And of course I'm interested if anyone has noticed similar behaviour, so I know it's not just something strange on my computer.
Thanks.
Ivan

I would have to say 40MB is by far the biggest example I've seen on my computer, but I have commonly seen what appears to be 10-20MB of download at startup. Still very large to start a program. It seems if you quit the app on the Updates screen, then it will go there by default, and that is a reasonably small amount of data used. It does appear to cache data, as subsequent startups on the same day don't use anywhere near as much data. When I just tried it again, for instance, it used a little under 1MB. So it is highly variable.
I will take up your suggestion to give Apple some feedback - thanks.

Firefox is using up all my CPU thus slowing my computer: add-on? or malware?

My computer has slowed way down mostly because of Firefox. I suspect an add-on, malware, or corrupt file in Firefox. CPU usage is 90-100%.

I am experiencing the same issue when ever I add a Genera iTune Pinwheels and starts using up all of my system memory. I took my computer to the apple store and they found that I had a bad Ram module. I will see if the issue persist after the new ram module come in. I hope it will fix the issue if not I will have to try uninstalling and reinstalling iTunes. What software are you using to copy the DVD I wonder if it is the software we are using to get the DVD to the Mac.

Tnsping.exe using 90% of my CPU time . HOW TO SOLVE IT?

Hi,
While im runnning my application which is using Oracle 10.1 release database(OS Windows XP) tnsping.exe is using 90% of CPU Shocked (while i check in Task Manager).Please help me to resolve this problem.
With Regards

Sorry,
Assuming 'processing a check' is considered to constitute a transaction, and Oracle can measure transaction time (which it can), why would employees need to enter this?
That doesn't make any sense.
Also, you need to check with the original developers why tnsping is called and, above all, where tnsping is called.
This call should be removed, and the tnsping process should be stopped.
Running tnsping continually doesn't make any sense.
However, you can not solve the problem. The application vendor should be called into action, and your client should replace the application asap.

How can I keep a state machine readable when using large amounts of in/outputs

Hello, I am new to Labview,
Read trough the fundamentals and the
getting started and a lot of examples.
What I want to do is use a standard
state machine from the template, and add some stages, for example
orange, apple, banana. At this point I can use numeric controls to
put in the amount of oranges, apples, bananas there are. I can even
use a led to tell the user which state of the state-machine is
active.
The thing is there will be more numeric
controls and more leds and it would be nice if the code would still
be readable when there are 20 inputs and 20 outputs.
Questions
(1) It would be nice if I could use the
typedef to select the right state AND the corresponding numeric
controls and leds out of a cluster or an array kind of structure to
keep the number of wires low. Is this possible, how can I do this?
(2) I tried to put the numeric controls
into a cluster but that way I can't put the numeric control for the
apples in the upper right corner and the numeric control for the
oranges in the lower left down corner of the front panel.
(3) An example would be really nice, I
know that I saw some examples describing this problem but there are
so many examples that after a few hours of searching I haven't found
the right one yet.
Thanks in advance for the effort.
p.s. I will not use Labview to do
calculations on fruit, I am only using this to make the question
easier to understand.

I can only start a proper answer but I might as well start with that.
When I am developing State Machines I have to think about what data is used and manipulated in each state. I then have to think about where am i going to keep and manage the data. I list all of the fields that are "touched" in each state and what values are used together and which are independent form the others. After this phase of the analysis, I usually have some data structure defined (cluser array etc).
Then I flipp from thinking about the state to thinking about the data (after all this is LabVIEW and the data-flow paradigm is critical). If I see data that is only used by the State machine and is used in many of the states, then the data structure get put in a shift-register for easy access in each state. This maybe enough of an answer for your fruity question.
When i see data that is shared or only used in a handful of states then I concider putting the data in an Action Engine. Depending on how you design your AE, you can access each of the fruit totoal by name or increment etc as required.
If your app demands many fileds that are all related (can't be broken into distinct data structures) then create a cluster that has all of your values that are used by the AE. Then create an Wrapper VI for each call of the AE but only put the associated fields on the FP of the wrapper and then bundle that value into the cluster and invoke the AE.

General question about storage, networking, and using large amounts of data

I have been using a powermac tower G5 up until now. I bought my daughter a macbook pro 15" i7, talk about a zippy little machine. What a screamer. I can't believe how fast it is with final cut express, Aperture, and Photoshop. I tend to use higher end stuff, video, photos, etc. Hence I need not only a good fast processor, but the storage....need lots of hard disk space.
oh, did I mention I bought this for my daughter who's about to go off to college? Heh, when I'm home, she loses the machine to me.... *evil grin*
Anyways, I haven't considered using a laptop before for me personally as I just don't care for the small screen size, no mouse, and things like that.
Seems I've changed my opinion, esp seeing as the new mouse track pad is a game changer. I still am not crazy about the small screen size, but I can get over it.
The one thing I can't get around is the small disk storage. I have 4 TB on my big machine. Between my video, photography, and music, I am nearing a full TB of just raw stuff. If I count all the things I've stored, especially finished videos I make of photography projects, well you can image the chomping that occurs on disk storage.
So what is a man to do about storage?
I'm really getting hooked on this zippy little machine. The idea of dragging it around is compelling. Having my work not tied to a desk is fun.
but the lack of storage is sucky, terribly so.
I have one possible option, taking the G5 and making it a server. I can use it for backup and high speed transfer, working on the transfer part today.
I thought I'd poll the collective wisdom of the community and see what do you peeps think is the best overall way to handle such a situation?
What is the absolute fastest best way to use external drives? Firewire 800 is ok, but when working with 400gb aperture database files....
I'm hoping there is some way to start posturing myself to really use a laptop for my full computing experience.
Or am I trying to make a small portable machine act like a tower? Is this not a reasonable hope at this point in time?
I'm open to suggestions. I'm going to purchase something when my daughter takes this laptop with her to college. Either a new mac pro tower or laptop. I love the portability but need speed and massive storage.
Thanks for opining.

Storage:
1. Replace the drive with a larger one. Up to 1 TB is now available for notebook drives.
2. Get a portable external drive for additional storage needs. See the options at OWC as an example.
Drive speed:
1. FW 800 should be fast enough for your work. If the computer has an ExpressCard slot then consider a card supporting full speed eSATA. You may then achieve speeds closer to the internal bus.
A laptop is not a tower so stop thinking of or comparing to your tower. Besides the laptop's speed compared to your G5 is more like comparing a Ford Focus to a Ferrari F150.

Firefox.exe uses too much memory slowing the computer down, what can be done?

This doesn't happen every time I am using the browser, maybe half of the time. When it does happen it takes a long time for it to clear up. It can slow the computer down even after I have exited out of the program, maybe still not responding because of high memory usage. Is there anything I can do to get Firefox to run smoothly?

Some updates are better handled by Internet Explorer or the built-in updater, such as any updates from Microsoft's Windows Update or Office Update systems. (These systems are not compatible with other browsers.)
You can use the "all systems" page to download a full installer and then copy it over to your XP system.
