Software :: Command Used To Get Usage Of Each CPU?
Jul 19, 2010
Machine using dual-core processor. I need to find out the load on each CPU core. I have tried using "top" command. But, top command is showing the overall usage of cpu. What is command is used to get the usage of each CPU?
So I want to see how high the temps get on my laptop with the new AS5 application. I know of a free program on windows that maxes out the CPu to 100% usage, but any app exist for OSX? I using SL. I have been ripping my home DVDs all day, but doing the same 3 over, gets old quick. Do any of you know any free app that will stress the CPU? Also is there an App that will stress the GPU?
Is this normal? I'm pretty sure it's not, at least the iTunes bit. I am using cover flo and I know that's supposed to increase the RAM usage but I don't even have the window open (it's in another space.) I've been seeing this high amount of RAM usage lately so I ran techtool deluxe and there was an error with the volume structure. I repaired permissions from the OS X install disk and since then the volume structure test passes but I'm still getting the unusually high numbers.
My computer has been running incredibly slow lately. I think it has to do with the disk usage as every time it has to access the disk, it slows to a crawl. I've had a huge amount of beach balling, especially when loading a new App or a new page in Safari.
Here is a picture of the disk usage. Does this look normal? Does anyone know what the problem could be?
I'm new to OS X and just had a quick question about the way that it uses memory.
I have the istat widget on my dashboard, and I've been monitoring the amount of free and used RAM. After I reboot the system, only about 20 percent of my memory is being used between the OS and the programs I normally use (adium, safari, itunes, etc.) Over the course of a couple days, the amount of used ram increases to about 50 percent, even though I'm just using the same programs.So, I'm just wondering how exactly the operating system deals with used and free RAM. Once the system uses ram for something, will that ram be reported as used until I reboot? Why does used ram continue to increase even though I'm doing the exact same things?
I'd just appreciate if someone could enlighten me on how the system uses RAM and whether I need to reboot every few days for optimal performance. I know it's still only using 50 percent (i have 4 gigs) - I'm not afraid of running out, I'm just wondering for my own knowledge.
I have an iStat Menubar and it's constantly showing me 40% CPU usage. It also shows the same number in Activity Monitor. However, when I look at the processes running, they don't add up to 40. In fact, they only amount to around 6% or so. I did click "All Processes", but nothing was running that would cause it to be 40%.
i want something similar to Window's Performance Monitor (Perfmon) on MAC. i need logs for the CPU usage of a particular process on MAC OSX. let me know if there is an in-built MAC utility or suggest some external application.
Just wondering if this is normal? Almost 30gb of VM in use? I'm encoding one of my DVDs and Handbrake is only using about 90mb of real memory while a bunch of background apps are using about 600-800mb of VM memory. Yesterday I encoded a DVD in like 20 minutes. I did a restart to refresh my memory but it's taken like over 2 hours of encoding and it's not done yet.
I've searched all over the internet but have yet to come across an answer. I love my Mac, but why is it that when I play a video in a web browser on my MacBook, (be it Flash, QuickTime, etc.) my CPU usage is anywhere from 60-80%, yet when I play the same video on a laptop running Windows, the CPU usage is always in the single digits?
I realize that video takes a toll on the CPU with integrated video cards, but it doesn't seem to have the same effect on Windows based laptops with integrated video cards. Is the CPU usage possibly just calculated differently, or is the Mac architecture somehow just really inefficient at this?
Whenever I start iChat on my new mini, it instantly spikes up the CPU usage and just sits there high. Activity Monitor says it's around 97%. I'm not doing anything in it; just starting the app gets it up there, and the only way to get it to go down again is to close the app. It doesn't seem to make a difference whether I'm online or off.
I've been trying and trying to get my 2007 Macbook C2D to run cooler. It idles at about 60-65 C even with no CPU usage (verified through Activity Monitor etc) and it used to get up to 95+ when playing any sort of video (Youtube etc) which would cause playback stuttering and other problems after 15-20 minutes.
I've tried a number of techniques to drop the temperature, most recently undervolting with Coolbook. Interesting, these have been relatively successful at lowering the *peak* temperature-- videos now only bump the CPU temp up to 70 C or so-- but it still idles at the exact same temperature it did before, around 60.
Does anyone have any theories why the idle temperature would remain high even after I've reduced the peak temperature, and even when CPU usage is hovering between 2 and 5 percent?
I have noticed that some of my programs when I run them take a massive amount of cpu usage and make my computer run very hot. This question seems like a stretch to me but is there any way to limit the amount of processing power a certain program uses? I don't really care if the program takes a longer amount of time to complete what it needs to do, I just don't want my computer overheating.
So maybe what I am looking for is in the activity monitor, but I just can't find it. I always see people on here posting screen shots of their CPU usage. If they have a quad core machine then there are four columns with blue in it showing the usage. Where can I find this in OS X, or is this a 3rd party program?
I have a two week old MBP and I find that my battery performance is dismal.I'm only getting 2 hours per charge, and this is after Apple replaced my battery two days ago!I think it might be related to my CPU usage..Looking at Activity Monitor, my "% User" CPU usage is routinely above 26%, with only Safari running (no videos). Even with no programs open I run over 25%.
My MacbookPro is running way too hard and makes me think it's going to die any second,I just purchased it new from the apple store back in September the CPU my Java takes up is amazing. I've seen the number jump to 102+ which makes me wonder why my computer freaks out when I use java. I've included a picture of the CPU usage.
I have a MacBook Air Late 2010, and the fan over heats at around 30% CPU usage, I installed AppTamer to keep it down, but it is quite annoying to keep using it. Sometimes the fan will go at 18% when one application uses about 15%, but not 100% percent when its lots of other ones. App that generaly cause the fan to overheat are, obviously, high CPU ones, like Pixelmator, Photoshop, Xcode, but some times even low CPU usage, like YouTube or Video Content on Google Chrome, Safari and Google Chrome in general. Microsoft Office 2011, Pages, Numbers & Keynote. Even apps like Preview (viewing more than 5 photos ) can use alot of CPU. So what should I do? I have repairs under warranty till about September, but Apple charge £35.00 to chat online?!?! I have tried resetting the SMC which only works about half of the time. I read on the internet that it is a production issue or at least common Late 2010 MacBook Air's.
