Kernel_task Root 584% CPU 745MB real memory
Machine has become really slow and throttled and the fans are very loud. Shut down, restarted, same thing. All software updated. Anyone know what's going on?

But not necessarily the same problem. Would you go to your doctor and say "You examined a friend of mine and I have the same symptom, so what's wrong with me?"
Large amounts of virtual memory are not abnormal. All that means is that the system has pushed a bunch of recently used data off onto disk to free up ram for other processes. If the processes you're running collectively need more active memory than you have installed in the machine or if you're boot volume is almost full things can slow down dramatically, but otherwise the size of virtual memory is not all that relevant.
pid 0 on my machine has 95 threads open, 700 Mb real memory, but only 49 Mb virtual memory. 4.5 Gb of virtual memory sounds excessive and my guess at a cause would be some third-party app or plugin or some such with a memory leak. As a diagnostic, try restarting in Safe Mode and see if the problem is still there. If it goes away in safe mode, then you'll to have to tell what 3P processes you normally run.

Kernel_task consumes a lot of real memory
(I do not speak english, all translated by google. Sorry.)
The process "kernel_task" of my MacBook Air is always occupying a lot of "Real Memory", always up to 1.5GB. Why? How can I solve?
Thanks and sorry bad english.Read this document.

Real Memory vs CPU usage?
I have a few questions:
- Should I look at CPU or Real Memory to find out which applications are eating a lot of power?
- Moreover, looking @ my activity monitor, I noticed Firefox and iTunes and Mail eating up much memory, is this normal or is this a Lion issues.
- What is " Kernel task " as conveyed in the image.. It is using up almost 1GB of ram!
- Moreover, am barely running anything huge, like AutuCad, and yet I have used 4.75GB of ram?Kernel Task is the OS - kill that and you won't be able to run anything
You're not using more than half the 8gb you have so don't worry about it.
Change Activity Monitor to show My Processes to see the sort of things you can safely play with.

My Mac is running very slowly. After reading other posts I have attempted to gather more info for an easier more accurate response but not being computer savy am unsure what is helpful/necessary. The utilized space is 231.6 GB with 88.13 GB free. Memory is 2.00 GB w/ 1.25 GB free and 771.8 MB used. The kernel_task root 1.1 63 205.3 MB intel. What can I do to increase the speed and stop the spinning wheel? Thanks for all your help.

870+ MB of kernel_task real memory immediately after boot
This is a 2012 MacBook Air 13" — 1.8ghz i5, 4GB
It's running the latest 10.8.3
When I boot, the kernel_task is already using 866MB of real memory. This seems very, very high.
Are there any tools or utilities that I can use to get a sense of what's driving that without iterating through uninstalling everything?
The only 3rd party kext is Little Snitch; kextstat shows that it has 0x46000 wired, which is only ~286kb.Normal.

Kernel_task keeps using more and more memory, threads. How do I fix this?
In Activity Monitor, kernel_task (PID 0, User root) doesn't take up much CPU, but has a huge number of threads open. It also has nearly 400 MB of real Memory, and over 4 and a half GB of virtual memory! This is slowing my computer down immensly. I tried restarting the computer, but it didn't help. Any tips on how to fix this?

Is it normal for Kernal_Task(0) to be using 600 MB of real memory?
I was running some diagnostics and I keep noticing that Kernal_Task is using a ton of real memory on my system. I just had the mother replaced (the original fried). My machine (macbook pro, spring 2011) is running pretty hot as well, although Kernal is not taking up a ton of CPU resources.
Here's a screen shot: http://imgur.com/yvAt0Probably not out of the ordinary. I just checked mine and it's at 574 MB.

Hello All,
Below is the server configuration,
OS: Windows 2008 R2 Enterprise 64 Bit
Version: 6.1.7601 Service Pack 1 Build 7601
CPU: 4 (@ 2.93 GHz, 1 core)
Memory: 12 GB
Page file: 12 GB
1. The actual utilization, be it a 15 minute sample, hourly, weekly etc, the utilization of real memory has never crossed 20% and the page file usage is at 0.1%. For some reason, the Pages/Sec>Limit% counter reports 100% continuously regardless of the
sampling intervals. Upon further observation, the Page Reads/Sec value is somewhere between 150~450 and Page Input/Sec is somewhere between 800~8000. Does this indicate a performance bottleneck? (I've in the interim asked the Users, App. Owners to see if they
notice any performance degradation and awaiting response). If this indicates a performance issue, please could someone help list down how to track this down further to which process/memory mapped file is causing it? and what I should go about performing to
fix this problem please?
p.s., initially the Security logs were full on this server and since page file is tied to Application, Security and System logs, this was freed up to see if this is causing the high page reads but this doesn't.
2. If the above does not necessarily indicate a performance problem, please can someone reference few KB articles that confirms this? Also, in this case, will there be any adverse effects if attempting to fine tune a server which is already running fine?
assuming App. Owners confirm there isn't any performance degradation.
Thanks in advance.Hi,
Based on the description, we can try to download Server Performance Advisor (SPA) to help further analyze the performance of the server. SPA can generate comprehensive diagnostic reports and charts and provides recommendations to help you quickly analyze
issues and develop corrective actions.

My mac is slow, the movies run slowly, the kernel_task consumes 463,3 MB of memory, how can I fix this?
The problem started a few weeks ago with a small decrease in speed, and the videos now crash while the sound remains normal. When I open the Finder or any file it seems that I'm opening the windows with the hourglass spinning. I've already cleaned temporary, removed everything that was saved on the table, I made up for the mountain lion. I have a Mac 27-inch, 3.06 GHz processor Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3, ATI Radeon HD 4670 256 MB, Software OS X 10.8. With space on the HD.

Karnel task taking too much Real Memory & Battery not lasting long.
Hello,
I've noticed under my Activity Monitor that Karnel_Task is taking too much "real memory".
Also, I just bought a new battery because the original that came with my computer was dying too fast.
Well, this new one lasts just a little longer. I believe that is something else that is eating up the battery.
I have a Macbook Pro 13' early 2011.
4 GB at the Moment.
Running Mountain Lion.
Processor 2.3 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Serial Number C17F4LJHDH2G
Software OS X 10.8.5 (12F45)
Here is my Etre Check as well. I need help figuring out what is wrong with my laptop and what to do to fix it please.

Why Does kernel_task use 80 % cpu?
Hi,
Ive been having a problem with my 2ghz macbook running slowly. The first thing i did when i noticed the slowdown was to open Activity Monitor to find out what process was causing the slowdown. kernel_task was running at 84% of the cpu and had 54 threads running. I restarted the computer and PID 0 kernal_task was still running between 70 and 90% cpu.
Things i tried to fix the problem
1 uninstall all programs and games
2 remove everything connected to the computer
3 boot to os disk and repair permissions ( on boot volume and disk itself )
4 reinstall os and download updates
5 reinstall os and don't download updates
6 reinstall os and choose "erase and install" option
7 boot to os disk and use disk utility to erase disk then reinstall os
8 boot to os disk and use diskutil from terminal to repartition and reformat, then reinstall os
9 reset NVRAM/ PRAM
after this i took it to the apple store. they put a new hard drive in it (probably cause i wore out the old one reformatting it) and the problem still exists.
most of the forums say that the problem is either overheating, or a kernel extension misbehaving. both of these explanations could be the problem.
Overheating-
many macbook air users report high kernel_task cpu usage related to high cpu temps, broken fans and broken logic-boards. this is further supported buy how the problem goes away when the ambient temperature is below 60 but comes back at room temp. could this be a hardware ploblem like a bad fan, bad temp sensor or heatsink that got popped off?
CoolBook
coolbook should help solve the temp problem buy lowering the voltage to the cpu, but that sounds uber dangerous to me. plus it adds its own kext's and im trying to fix the kernel not add a bunch of 3rd party junk to it. has anybody had any luck with coolbook?
Bad kext (kernel extension)
when i boot to safe mode kernel_task behaves normaly so could the problem be a bad kext? safeboot only loads the required kernel extensions so could one of the other kexts not loaded in safe boot be the problem?
1 first question: kernel_task is a process scheduler and memory manager so is messing around with kernel extensions going to have any affect?
2 some people found that replacing the trackpad kext with an earlier version got the kernel_task to settle down has this worked for anyone?
3 i booted regularly and in safe mode and used kextfind -loaded to find out what kexts were running normally that didnt run in safe boot. I then booted to safe mode again and used kextload to load back each kext one buy one. they all loaded and kernel_task stayed the same. there was one exception GeForce.kext caused a panic and wouldnt load. is geforce.kext the problem or am i on the wrong track?
4 the way i understand it kextd is a daemon (whatever that means) that loads kernel extensions. the man pages say that the "-x" switch will make it only load the safe boot kernel extensions but kextd doesnt work from the command line because its started buy launchd (right?) is there a way to get kextd to start with the "-x" switch every time the computer boots normally?
Im a total computer noob and i welcome and any correction and advice at any level. please help me! i want to solve this whole kernel_task for everyone once and for all!

Message was edited by: DuezleHave you counted the number of processes in AM? They are all running from time to time whether you use the computer or it sits for an hour. Not including applications you have loaded there may be upwards of 80-90 system processes running. Applications you aren't using are still partially in memory and partially being paged out to disk.
All this activity will in part use the kernel. My kernel_task process is running 1.5 GBs just now. -
Kernel_task is using a lot of memory
I am curious if it is normal to have Kernel_task take 1.8 GB of memory? It seems to be the consistent reason as to why our server is running slow? Thanks for any help....
This looks like the solution, but I cannot get the commands to work. When I enter the command to make a command of /et/rc.server using the root login, it says:
-sh: $: command not found
How should I enter this command using terminal? thanks, I am really new at this, but I am doing my best to learn. As an aside, is there a site that helps getting started with terminal?
As always, thanks!!
You can make the following change to /etc/rc.server to improve performance in this situation. This is recommended only if your server has 2 GB, 3 GB, or 4 GB of RAM.
Make a copy of /etc/rc.server with this command:
$ sudo cp /etc/rc.server /etc/rc.server.bak
As the root user, open /etc/rc.server in the text editor of your choice.
Locate this line in /etc/rc.server:
sysctl -w kern.maxnbuf=90000
Change the number 90000 to 20000, so that the line reads:
sysctl -w kern.maxnbuf=20000
Save the changes made to /etc/rc.server.
Restart the server. -
Full use of installed "real" memory not used.
Hi
I have a Power Mac G5 (Dual 2GHz), running OS X Tiger 10.4.11.
When you upgrade RAM, does the OS automatically make use of this or do you need to make system changes? I ask because I have 3GB of RAM and I never see it being fully used. I've tested this whilst using apps like Photoshop CS3, and monitoring RAM useage via Activity Monitor. I understand Mac OS X makes great use of virtual memory, so when does real memory come into action?
Thanks
gtdsThe memory being recognized by the system is what is shown when you select +About This Mac+ from the Apple menu. You can also run System Profiler for more details. If that shows 3 GB of RAM as expected, it is being recognized and the Mac will use it when needed. Virtual memory is still used, but it will be used to a lesser extent with more RAM installed.
If there is a lot of green in Activity Monitor's diagram of System Memory usage, that is good. If you run multiple large apps such as Photoshop and actually do some system intensive tasks, you will probably see less green, but RAM usage is not like CPU usage; Mac OS X is not going to use the RAM just because it's there. It will use the RAM when it is needed.
If the Mac is not recognizing the expected 3GB of RAM, that's a problem. You should run System Profiler to see what modules are not as expected. -
Kernal_task real memory high (493.4 MB)
I'm having trouble trying to figure out why my kernal_task's real memory is so high (it fluctuates up and down around 493.4 MB). I booted my MBP in safe mode and checked my activity monitor and it was running about 201 MBs. Right now as I am typing this I have no external devices hooked into my computer except an external monitor but i'm pretty sure thats not the problem. My computer gets real hot, real quick and I don't know how to bring the kernal task's real memory back down to or below 200 MBs. CAN ANYONE HELP ME PLEASE! It would be much appreciated thank you.
So here is a complete list of what is going on in my computer in Activity Manager (left out all the other columns for easy readability, if I need to add any back in for any help let me know):

Jdev11g CPU profile and Memory Profile doesn't work for Mac
I'm running Jdev11g on Mac OSX 10.5.5,
CPU Profile and Memory Profile doesn't work. I got following message:
Error occurred during initialization of VM

The file actually is there. I don't understand why they looking for .so file, it supposed to be mapped as .jnilib on Mac.
This is broken on TP4 as well.I'm still seeing this issue. Here is what I get:
