High CPU load with no proof from processes

I have a problem with my CPU load monitor.
In Activity Monitor, the processes that are showing do not reflect my actual CPU load.
At any given time the highest process shows 3% cpu load, but the percentages under the cpu tab show that the cpu is running at 50% (basically one full core processing SOMETHING).
Now I need to figure out what this "Something" is and kill it?
Anyone have any suggestions on how to find what bogging my system down?

hey, i know someone linked the other post i created, however ill give you the rundown quickly with out my babble (i was hyper at the time :p)
Go into your sharing control panel, services, turn OFF windows sharing. It seems for some reason teh netbios daemon is loading over and over again, most likely due to an error. it is restarting a few times a second creating the loads, in my acse atleast.
let me know if it works for you, if so im going to contact apple just to inform them since the tech I spoke to had no idea what it was.
good luck!

High CPU load with nfs4

Has anyone noticed a high cpu load when transferring over nfs4.
My arch box has a dual core amd with 4 gig of ram. It has a rocketraid 2320 card being used for a 8 1TB mdadm raid 6.
I am transferring from ubuntu -> arch box. I am noticing high cpu on both sides. I dont know if its an nfs issue or what.
On the arch side I am seeing high usage from nfsd , flush-9:0, and an mdadm process. Both cores are sitting around 50%.
Anyone run into this or know if its an issue with nfs4? or maybe different nfs versions of ubuntu and arch.
Thanks.

Adobe need to realize that once their great product with a lot of penetration into the web ad + ria market is starting loose its ground as they simply can't address ongoing issue on their poor flash plug-in performance other than on windows platform.

Only suggestion that I have with Adobe is that if you can not get it right then, it may help to open up flash player source to the community. I am pretty sure that there are a lot of developers out there who can help out to drive better code base for the player and in turn make flash more adopted by non non ms windows user base. At the moment, I have installed "Click2Flash" and "FlashBlock" to save majority of CPU cycle on my MacBook Pro. Imagine the impact on this for future Adobe product. All online ad will slowly move away from flash based and in turn loosing entire market share it has successfully built over the years... Well must note that MS isn't much better either... MS RDP client is permanently turned off from my system, now I'm using CoRD instead..
I sincerely hope to see some major performance improvements in near future.

Problem... High CPU load with HDD. Please Help

Hello all,
Im stuck. Ive got a MSI KA790GX which has poor HDD access/transfer, low burst rate and very high CPU load.
As far as i know the Western Digital 640gb WD6401AALS Black should be a fast hard drive. Which according to reviews/HD Tune,
should be:-
Minimum 60mb/sec
Maximum 120mb/sec
Average 95mb/sec
Access 12ms
Burst 110mb/sec
CPU 5%
No matter what I try, i always get poor results...
My MSI KA790GX
Minimum 41mb/sec ~ 54mb/sec
Maximum 104mb/sec ~ 108mb/sec
Average 86mb/sec ~89mb/sec
Access 12ms
Burst 60mb/sec ~ 80mb/sec
CPU 26% ~ 44%!!!!!!!!
I could accept not getting the same high speed results as the review/reference, even if the burst rate sucked.
But one of the cores goes to 50%-60% load during hdd activity. Thats just crazy!!
I have tried...
IDE mode, AHCI, RAID Ready, RAID Single Disk
SATA Port 1, 2, 3, 4 + 5
Different SATA cables
Flashed bios, cleared bios, optimised defaults, failsafe defaults
Windows XP 32bit, Vista 32bit, Vista 64bit. fresh installs
MSI CD Drivers, MSI Web Drivers, AMD/ATI Web Drivers
... and combinations of.
I have also tested the WD640gb Black on another older PC, with Nvidia (55?) chipset and slower (1.9ghz x2) cpu.
Transfer rates were slightly better than my KA790GX but, Burst Rate = 115mb/sec and CPU usage = 13%.
I also tried a Seagate 1.5tb (ST31500341AS) on both PCs,
Nvidia chipset
Minimum 65mb/sec
Maximum 134mb/sec
Average 107mb/sec
Access 14ms
Burst 83mb/sec
CPU 7%
On my MSI KA790GX
Minimum 55mb/sec
Maximum 120mb/sec
Average 100mb/sec
Access 14ms
Burst 87mb/sec
CPU 33%!!!!
Could someone please please help, ive spent hours and hours on this. Its doin my head in.
I just hope its something stupid ive missed, cos i still not used my HD4850 from christmas :-(
Thanks.

Not sure how to check PIO/DMA mode on a SATA device. IDE devices show DMA enabled.
BIOS version 1.4 - 29 December 2008, and now version 1.51
Fredrik
I have Vista 64, but i did try XP32 and Vista32 and got similar poor results.
I tested HDD speed with, HD Tune 2.55 and HD Tune 3.50 trial.
No auto-start programs really, Windows clean installs + any drivers.
Quadrifoglio Verde
CPU @ default 2800mhz, All mem bios options to auto/defaults
Windows Experience Index, CPU Score = 5.3
AMD Overdrive
Integer Computation = 8220
Floating Point Computation = 5325
Memory speed = 1770
Cache Speed = 10790
System Performance = 7403
Bas
I used HDTune because I could reference to other results. Whats a better program to use?
Windows Experience Index, HDD Score = 5.9.
But I have no reference and cant be sure of cpu load.
Sepher
Bios defaults to C&C and C1E off so i have tried them. Also windows power settings, balanced/high performance.
UPDATE
Reinstalled Vista64 but loaded the AHCI driver from the disk config screen. This seems to have stopped the high cpu usage during disk activity.
HDTune with Windows Power settings @ High Performance,
Min = 52mb/sec
Max = 106mb/sec
Ave = 88mb/sec
Access = 12ms
Burst = 77mb/sec
CPU = 3.4%
HDTune with Windows Power settings @ Balanced
Min = 54mb/sec
Max = 104mb/sec
Ave = 87mb/sec
Access = 12ms
Burst = 65mb/sec
CPU = 12%
So now transfer speed is about 10% slower than reference. But burst speed is terrible.
I also used IBM Feature Tool to change the HDD AAM to 'performance mode' 254 as suggested elsewhere.
Long shot as the hdd performs ok with other hardware. same results.
Also MSI support asked me to try a newer bios, version 1.51. same results.
Anyone know what the AMD 7-Series Chipsets Disk Performance Utility does, and should i run it in Vista64?
Thanks for all the replies, hope i can sort this, not played any PC games since Quake 3 on my ti4600...

High CPU load with Flash on Mac Leopard

Dear Adobe,
I am always running the latest version of the Flash plugin on my Macbook. Ever since even with the simplest Flash movies running in a browser (no matter whether Safari, Firefox, Camino, Opera, ...) the CPU load jumps oh so high the fans will spin at full speed and the CPU starts to create subtropic temperatures. Years ago I was running a Windows PC where the CPU load wasn't even close to such high CPU loads. Oh so many Apple users would very very much appreciate Flash Player being at least close to as efficient as the Windows version.
Thanks in advance for making Flash movies more enjoyable on the Mac platform

Too high cpu load with HP 6510b

Hello guys,
I have a very high cpu load on my laptop even if nothing despite htop is running. I guess it's a problem with acpi because when I deactivate acpi completely over the bootline I have no such problems.
How could I fix that?
Thank you in advance.

Hello B,
unluckily noacpi doesn't help but acpi=off. That seems to be the only way to stop the high load.
Is there any patched acpi or something else?
I also think I picked the bad revision with fan problems and some more...

High CPU Load with Alesis Multimix Usb 2.0 mixer

Hi everybody,
i'm still playing around with logic studio 9, mainly mainstage 2.1.1 for a possible future live use.
Today i tried to use my Alesis Multimix 8 usb2.0, just as the output devices, using software instruments with a m-audio keystation.
I always get cpu peak load when playing notes, with every patch, either internal apple instrument or third party au instruments, when idle cpu load goes to about 40%...
If i revert back to internal output / internal input, cpu load drastically goes down to 10% idle and max 50-60% with internal instruments,max 80% with 2-3 layers of third party au instruments (Omnisphere, loungelizard, m-tron)...
I know that Alesis mac drivers for snow leopard are at a beta stage, but am i the only one experiencing this or is it a known problem?
Thanks,
Alex.

Hi Pan,
i made a different test today...
I know it's not the same but i tried using a guitar rig on mainstage (guitar on channel1 in the mixer), and even with 256 samples i ALWAYS get 100% cpu usage...
then closed mainstage and opened NI Guitar Rig 3 as standalone, using the alesis as interface, with 64 samples as buffer, i cannot go over 13-14% of CPU usage (Hi quality enabled)... I know that mainstage adds more effects than the ones i selected in guitar rig 3, but the HUGE difference in cpu usage cannot be just that, i mean...
It could be if one of the effects Mainstage was using is Space Designer.
If it is using Space Designer try using a lesser reverb, like Gold.
USB doesn't use that much more CPU so that's not the problem.
You are comparing two separate guitar setups, correct? Or do you mean you're opening Guitar Rig 3 in Mainstage?
pancenter-
As I understand it you are opening completely different setups, correct.

High cpu load with Skype

Hi, i am currently using macbook pro and i am not sure why when i run skype the cpu is eat up to 90% and the fan start to make noise. is that any way to fix this issue. thanks alot. P.S i use mac os 10.7

Yes I was trying to pinpoint the action that causes Skype to go 100% When it does it uses two cores and the battery is drained increadibly fast.
I will let you know if I find out. Otherwise restarting and/or removing the $HOME/Library/Skype data does the trick of fixing it.

Flashplayer 11.3 high cpu load + stutters

Hey all, I recently updated my Flash Player Plugin for Firefox to version 11.3.300.268. This results in a high CPU load for the Flash Player process like 30 to 40 percent with a 480p YouTube video and some higher percentages when watching flash video on other websites. The highest percentage must have been like 70% while watching a simple flash video on another website. This high CPU load is not the only problem. The video/audio stutters from time to time and especially when you open a new website, even light ones like Google.com. This problem occurred before but at that time I downgraded my version to flashplayer11_1r102_63_win_32bit.exe which is the latest version of Flash that is working correctly on my system.
Some specs:
Windows Vista Home 32-bit
Intel Celeron M530
Intel 965 Express Chipset with latest installable drivers via HP website (7.15.10.1839)
Firefox 14.0.1.
Possible solutions that had no effect:
Turning off HW acceleration in Flash settings.
Turning off HW acceleration in Firefox settings.

Same issue here. I'm going to downgrade as well, as it's making watching embedded videos very frustrating.

DMVPN phase 3 - scalability - nhrp generates high cpu load

Hey all.
Been running into a scalability issues with DMVPN. Mainly caused (as I see it) by NHRP.
Scenario:
IOS-SLB-based DMVPN solution in a dual-cloud setup. Practically it's 2 separate solutions with spokes having 2 tunnels (one in each cloud). See attachment sketch. We're running a phase 3 hierarchy design (trying at least)
Spoke routers:
- 2500 routers in a mixture of c871, c881, c2800, c2900. Need to scale to at least twice that.
- Spoke-to-spoke is heavily used
Farm routers:
- Cisco 7201 with VAM2+. Around 1 router per 350 spokes (+1 for secondary tunnel)
Superhub:
- ASR 1004 (one for primary and one for secondary dmvpn-cloud).
We're not running any IPSEC between the farms and the superhubs. Just regular unencrypted DMVPN (mGRE).
Problem:
- NHRP is causing high CPU load on the ASRs. With around 2000 spokes up and running on DMVPN the CPU is overloaded with NHRP traffic. We're talking like 60-70% load caused by the NHRP process alone!
We're using 'ip nhrp interest' on all the spokes - and farms. We're in need of the spoke-to-spoke functionality so we allowing LAN-segments of our customers but denying everything else.
Solutions?
1. Turning off all NHRP resolutions? Basically remove any directly spoke-spoke communications (denying everything on the interest list). We can't go there since a lot of our customers are in dire need for directly spoke-spoke connectivity (due to latency). Haven't tested that it will actually give the much needed scalable solution either (we're facing around 5000 spokes in the next 2-3 years).
2. Chopping the DMVPN solution up in lesser VPN-blocks. This will administratively be a nightmare.
3. ?
Will really appreciate if anyone have a input here. It's really hard finding anything about a LARGE scale phase3 design on the web. Everything I find seems to mix stuff from small-scale phase 2 and 3 - making it rather messy cooking reciept for a small breakfast while I need a 7 course perfect dinner
When will Cisco come with an updated design guide btw?
Thanks in advance!

Thank you for your quick reply.
Our ASRs (rp1) are acting as BGP RR while the farm routers are setup as RR clients.
We haven't tried connecting spokes directly to the ASRs but we have seen the same symptoms on the 7613s (sup720) and the 7200-platform.
Earlier the 7600 had the same role the ASRs have today. We were expecting that the ASRs should be doing "a better job" in terms of CPU load but we were wrong (NHRP generated around 10% more cpu load on the ASRs in comparison).
We concluded that the ASRs have a less optimized OS (coding) being rather new and all. Further we're not all happy about the stability of the platform (clear ip nhrp or taking a shutdown on the tunnel in the current situation will crash the router. 15.1(2)S1 and 15.1(3)S0a adv ip services). Haven't made a TAC case of it yet but will (has to be a bug as I see it since the 7200/7600 is handling this just fine).
Due to what I mentioned above I don't dare to debug the problem in production time and have to wait until the next scheduled maintenance window for some decent debug output (24. Oct).
We've contacted Cisco AS for assistance since it's hard to find local consultants (Norway) with enough knowledge of such scenario.
I just hope it's a config-issue and not a design issue, but we're willing to to whatever for this to scale to the thousands.

High CPU load

We use vSphere 5.5 with latest updates, Web Client and the VMware Remote Console 7.0.1. But we have problems on our Citrix Terminalserver (Windows 2012 R2): When we close a Remote Console, the prozess "vmrc.exe" didn´t disappear and causes a high CPU load (one complete core). This happens when we use the IE, Chrome or Firefox.
I don´t know why this happens, have anyone an idea? Thank you!

One thing to check is that there isn't some other process running in the background which is also using a lot of the CPU. Open Activity Monitor and select "All Processes" at the top and "CPU" on the bottom bar. If you find some process other than the BOINC that is using a lot of the CPU, highlight it and quit it and see if this helps.
If you haven't already, install iStatPro from the Apple site and keep an eye on your computer temperatures and on your fans. As long as your fans are working properly, they should keep your processor cool enough to not overheat.
It might also be worth investing in a chill mat, just to help keep your Mac cool overnight.
Good luck!

High CPU load kills ethernet connection

Short spikes in CPU load (MenuMeters installed) are constantly killing my internet connection.
I use an ethernet connection with a cable modem (Motorola SB 4200 E) and have a MB 2 CD, 2 GB of RAM and OS X 10.4.9.
After the ethernet connection is killed, only a complete re-start can fix the problem (and today alone I had to do something like 15 of them already).
These sudden spikes in CPU load can be caused by all different kinds of activity, e.g.
1.) playing back video files which my machine has problems dealing with (like .mkv files),
2.) playing back 'regular' .avi files,
3.) browsing the net (Camino, Safari, Opera, Firefox) and displaying flash content (just watching something on youtube creates a CPU load which kills the connection regularly),
4.) any kind of activity which asks a high CPU load in general.
It seems that the problem is caused by the CPU load in general, not by any particular application which causes the high workload.
What I have tried:
1.) PRAM reset
2.) Apple Hardware Test (extended, loop)
3.) de-installed Flash player
4.) created a new user (admin)
5.) made a clean 10.4.11 install on an external USB drive and booted from there
6.) used Airport instead of the ethernet/cable modem
7.) checked system temperatures (which are ok)
8.) changed/exchanged/checked the RAM
9.) made enough free disk space on my HD (15 GB)
10.) repaired disk permissions
but to no avail.
Any help would be very much appreciated (since I'm ready to get a MS machine and wave my Mac good bye).
Kind regards
FC

Osx 10.9 Mail & Safari High cpu load

Hello,
A few weeks ago I updated to OSX 10.9. After working a few days with it, I run into several high CPU load issues.
2 processes: mail-webmateriaal and safari-webmateriaal (dutch).
Now I use Chrome instead of Safari which solves 50% of my problem, but it is not so easy to change to another mail-client...
Does anyone have a clue about the possible cause, but even more important, a solution?
Best regards,
Johan

jvdstoel,
Ditto. I have the exact same OS 10.9 issue on a Late 2008 iMac with a 3.06 GHz Intel Core 2 Duo that is maxed out at 4 GB RAM (seemed like a lot of RAM at the time).
Mail, Safari, and Firefox--but not Chrome--whether running any 1, 2, or all 3 programs together keeps the CPU running hard at and often above 100%. This occurs even when the programs a sitting idle from the user's perspective. Disabling all extensions on Safari and Firefox did not help. Nor did running Onyx to clear all catches system wide.
Calling on anyone with a virtual PhD in Maverics (or real Apple OS 10.9 street-smarts) for suggestions.
Best,
Pete

Kernel task over 100%. High CPU Load. High Temp. Problem Solved.

Hi,
I thought i would make a post as i had been having trouble with my 13 inch mid 2009 MBP for sometime (6 months), with runaway kernel tasks causing high CPU loads. I had searched through forums and discussions for a long time trying to find the problem and isolate it. Initially i discovered some problems with finder preferances that were chewing up CPU which i solved by deleting the prefereance file, allowing the system to recreate a non corrupted version. This helped but still i had problems. I tried maintainance suites like onyx, reseting PRAM, booting into safe mode, hardware checks and diagnostics, and more little tricks than i can remember. Nothing i tried really seemed to make a differance. Through reading on this forum and others i found out the kernel tasks can be a direct result of hi CPU core temps as the system runs a lot of small kernel tasks to try and take some of the CPU load away from processor intensive processes that may be contributing to hi CPU load. The thing which solved my problem in the end was opening up my MBP, being careful not to touch the logic board and literally puting my vacuum cleaner over the fan, sucking dust and dirt and dust out of my latop. This computer has been through the dirt with me, literally its been dragged through rural south east asia for a year and accompianied me to warhouse parties to perform and run lighting and visuals. Its little wonder the fan was obviously clogged. I know people tend to be holier than though with their mac products and treat them with the upmost respect, but my love for the MBP has come from how sturdy and reliable it has been under less than desirable conditions.
Now im not telling people this is what they should do, i had just noticed alot of people with this problem in my attempts to solve mine, and in the end this is what helped. My MBP now runs at a temperature where i can touch the metal near the CPU without being worried about a 3rd degree burn and the CPU load is acceptable with no run away kernel tasks. Like i saw this might not be the cause of your porblem, as my laptop has lived a rough and fun life so far, but i thought i would share this with you all as i have had contstant help from this forum and others searches for solutions to problems with my apple products.

Already tried SMC and PRAM-reset with no luck.
On my MacBook late 2008 it's the same effect.

High CPU load on 2811

Hi,
We have a 2811 router and we are facing high CPU load but show proc cpu does not show processes with high CPU utilisation.

This does not happed outside working hours. The router is used only for VPN's (No NATing). It terminates around 25 tunnels but there is not a lot of traffic through the tunnels.
The extremly high load started mondat morning and continues this morning. During the weekend it was fine. Earlier we would have situations when the CPU would spike but it would soon be down to normal values.
From what I read the above output means that the CPU load is caused by interrupts. What is the best way to troubleshoot this?
Regards.

Sorry I wasn't clear, but when I was asking about "not a lot of traffic", I was wondering about actual volume passing through the 2811.
When I asked about "kind of tunnels", I was wondering about how they are configured. E.g. GRE or IPSec/GRE or VTI, encryption options, other tunnel interface options.
Perhaps the easiest way to check for fragmentation, is packet analyze the traffic passing through the 2811.
