Mac Pro :: New Seems Slow In CPU-intensive Task?
Feb 23, 2008
I have a new Mac Pro (standard 2.8 configuration with 3 X 250GB in software RAID0) at my cable station at college. I was expecting this thing to be a real screamer, but I find myself a bit disappointed. Don't get me wrong, it's still quite fast. But for CPU-intensive task in Final Cut Studio, I find it to be slower than it should be. For example, compressing a 6 GB DV file for an iPhone is taking 32 minutes. CPU usage is only around 30% per core. I've never been able to drive CPU usage above this level in any task (Handbrake, Final Cut rendering, etc.) I know that not all software is able to fully use all of the cores, but this doesn't make sense to me. Is this normal performance? Or could something wrong with the Mac Pro?

I have a Black Macbook. 2.2ghz, 1GB Ram, running Snow Leopard. Recently I've been finding my laptop rather sluggish and slow when performing tasks and opening applications. Firefox will often be quite slow at performing mundane tasks as well as flicking between applications that are open which is also slow. I use a couple of apps to help clear out unnecessary files etc to help with performance and stuff but clearly this doesn't appear to be working.

Is it at all possible to play a graphic intensive game, with as little lag as possible on a mac mini via vnc or some other streaming software from an imac or mbp running windows?

I have a late 2008 unibody Macbook Pro 15" with, unfortunately, only 2GB RAM. My work requires a very intensive internet flash application that will usually max out my RAM, and in combination with certain other applications, my computer becomes so laggy that I cannot work.
This has me wondering... which browser is best for running intensive flash applications? I also like to run lots of random pages at once, so I'll do that as well, either in the same browser, or concurrently in a different one.

Computer: Macbook Pro 15" 2.0Ghz with Rosetta, ATI X1600 graphics card, 1 gig RAM.
Problem: There will be horizontal pixel lines when the temperature goes above 50 degrees celsius. The computer will freeze in games randomly (particularly Warcraft III).
What I've noticed:
Apple+Q and Apple+option+escape does not do anything. Because it forces me to restart, I have no logs.
Other Macs can run in temperatures over 60 degrees celsius perfectly fine while mine cannot. When I put it on an A/C unit set at 40 degrees fahrenheit, I don't get any horizontal lines or freezes. (maybe the mac shuts off things at a particular temperature to prevent overheating and the set temperature was lowered)
Freezes vary from instantly going to a black screen, a green screen with vertical white lines, or just a normal freeze.
In a normal freeze, if I have iTunes playing in background, it won't be affected and will continue to play the song. (background processes may still be fine).
The green and black freezes will make the same sound repeat over and over.
Warcraft III (in-game) will sometimes start flickering in large random areas of the screen and it usually leads to a freeze.
Sometimes it will freeze even when the temperature isn't hot. (without warning)
What I've done:
reinstalled the OS and just installed Warcraft III to test display (still froze)
replaced the thermal paste
cleaned out the dust

I recently purchased a new 2.8 GHz iMac. I know that AVCHD is highly processor intensive but surely I should be able to play back Full HD video on a brand new computer! Using Toast Titanium 9 to play the files I'm getting ~20 fps on a 30 fps stream! Editing is not an issue because Final Cut/Apple Intermediate Codec take care of playback but I want to be able to archive the unedited AVCHD and that means I need to be able to view the raw files later. My CPU averages ~25% idle while playing back the video. Does that mean the video card is the bottleneck?

I've had numerous, yet infrequent, kernel panics with my 2010 15" MacBook Pro running Snow Leopard. I have a dual-core i7 model with the NVIDIA GeForge GT 300M. They always happen when I'm using a graphic-intensive program (Motion, Photoshop, and - believe it or not - when running PowerPoint presentations). They have all happened when using an external monitor or projector as well - although I rarely work without an external monitor plugged in, so it could be a coincidence on that. The maddening thing is that they don't happen all the time (well, I guess that's good) - sometimes they come at the start of the day when I'm first in a program, some come later in the day, some come when I've been using a program intensively (as in working in Photoshop for hours), and some just seem to happen right away when I first start using the program. There will be days I get multiple ones, and then not see the panics again for weeks and weeks.

I've been experiencing an incredibly frustrating issue with my MacBook Pro. Essentially, until the fan kicks on, it is performing as a computer with its specs should run. At the moment the fan kicks on, it becomes virtually useless. Really, truly glacial.
I have a first-generation unibody model (you know, the ones with the detachable battery). It has repectable specs–2.53 GHz Core 2 Duo, 4 GB RAM, NVIDIA GeForce 9600M GT 512 MB. I have also completely re-installed the newest version of Lion from scratch, as well as fresh installs of Adobe Creative Suite + Lightroom. Everything is totally fresh. No funky drivers from God-knows-when eating up my CPUs. So here is what happens: On a regular day (I'm a photographer), I'll open up Lightroom, Photoshop, and Spotify. The computer operates at a very decent clip, nice and snappy. Without modifying ANYTHING, my fans will kick on, and I'll have about 25% of the performance I had, literally, 10 seconds earlier. I have been exhaustive in diagnosis. I'll explain. Checked Activity Monitor, and everything looks completely normal. The programs and processes that I anticipated would be eating CPUs, indeed, are the only ones that are listed doing so. Nothing funky. I have installed Fan Control to monitor the speed of the fans as well as temp of the computer. Everything looks normal there, too. Along with reinstalling my operating systems, I decided to re-build my Lightroom albums. As of right now, there is only one shoot in the entire program. No gigantic libraries being indexed. I also make sure to build all of my thumbnails in advance so when I'm working in Photoshop, Lightroom isn't doing that in the background. About every hour or so, I'll close down Photoshop and Lightroom, and re-open them to clear caches. Only the fan affects the performance. And yes, I have broken open the back of the machine and gave the fans a cleaning. ****, they weren't even that dirty. It's also important to note that, yes, the fans kick on very quickly after opening up intensive programs. Even if I am just starting up a completely cool computer, and the programs have only been open and idle for a matter of minutes. Now should Lightroom with ONE WHOLE shoot cataloged be considered "intensive" for a computer with my specs? I don't even know anymore.

I have a graphics problem with my first generation iMac Core Duo 17 inch. It seems that in numerous areas throughout the OS, particularly in graphics intensive areas. It's irritating when I go to work on a Final Cut Pro, or when I want to fold, i see nothing but garbled parts of my screen!

I have a task called 'named' running and it's taking up 100% of a single core (swtiches cores periodically, but 100% when it does). Any idea what this is and whether I can kill it? It looks like it belongs to Internet Sharing.
Edit: I just turned IS off and it disappeared. Turned IS back on and it seems to have killed 'named'.

recently I've noticed that my task bar doesn't let me know what programs are running. For instance, normally when a program is open, there's a small white dot under the icon, meaning the program is open. Now that doesn't appear anymore. Can anyone explain how I can turn this option back on? I might have inadvertently shut it off somehow.

There is this icon on my task bar that I can't seem to get rid of. I downloaded and installed an application to format an external drive, then when I wasn't happy with it, I deleted it. Unfortunately, when I deleted it, it didn't delete the icon it put in my task bar. I can click on it and get a menu and do a number of things. At the bottom of the menu I can choose "Disable DrivePulse". Nothing happens! I go to system preferences and look at my login items and it's not there! I find it in activity monitor, quit it from there, and it comes back a second later! I search my mac for Drive Pulse and Drive Genius 3 and I get no results! Can somebody help me disable this nuisance permanently? Is there a hidden file on my HD I have to delete?

Does anyone know of a task app that has the option to remain open and like pinned to the desktop? I've found some nice to-do apps that ive tried to use by my biggest problem is that if I dont see it all the time, I wont get it done- and I usually only open the app to add things to my "list" only to see things that I was supposed to have done!!
I realize that I could just leave the application open all the time, but that just doesn't seem to work for me, I like to see my background and I dont like having numerous windows open...

I'd love for my computer to automatically go to the page with the new image on it and save it to a folder. Sometimes I jsut don't have the time to get over to the page, or I jsut simply forget. Is there a way to automate this process?

Is there any specific reason Kernel_Task seems to think he owns the place? What gives? It's like I turn my MacBook on and he's all like "oh hai! Ize just a system task! 50mb of memory? That's cool that's cool" Then only 2 hours later he's all like "Nah man, I just needed some more room see, it's like 120mb ain't dat much, k?"
I know that OS X handles ram real good and all, by freeing memory when it's required for higher-priority tasks, but I also know that it takes a bit more time to clear that memory AND re-allocate it...
So, is this a memory leak? And while I'm at it what about iChat Agent and Colloquy that are battling out to be RAM champ?
OH, and I haz 2gb installed at the moment.

Mac OSX 10.5.6When I have several applications running and one finishes a task it automatically changes to that space without asking. This is very annoying when I am in the middle of something in another application in another space. Is it possible to just get the icon to bounce instead of changing spaces like it did before using spaces.

I just tried to move some critical data from one drive to another and the operation froze. The folder showed up in the destination but then the copy wouldn't start. What was the problem? Apple apparently set its automatic reminder for the Software Update application to a higher priority than the user task. After a few seconds of being frozen, the folder disappeared from its destination and the Software Update window appeared.
Why is a background application more important than a file copy that was initiated by the user? What was so important that it had to interrupt my file copy? A Safari point update, something about Digital Camera RAW Compatibility for iPhoto and Aperture 3 (neither of which I use), and an iLife Support point update (which I also don't use). Is there a way to tell OS X that whatever I'm doing with copying or moving files should always have a higher priority than any background tasks?

I've been recently realizing that every time i use safari or socialite for a few mins I get a lot of 'beach ball' time. The application would show in red (not responding) in activity monitor and kernel_task would have over 1,900 threads, that will decrease slowly after I force quit the applications.

My computer keeps freezing and applications keep shutting down unexpectantly. So when I went into the activity monitor I saw that Kernal_task and inkjet1 seem to be taking up the most CPU, threads, and memory. What are they? How can I make my computer more efficient? Are these processess causing my computer to be so slow and freezy?

I have been experiencing the fan running at high rpm and the computer completely slowing down when there is slight pressure applied to the bottom of my macbook pro. I went on Activity Monitor and it shows kernel_task running at over 100% cpu usage. I have already tried resetting PRAM and SMC but those did not work.

I was working on my Mac but is coming very slow sometimes so I found the problem is the kernel task.
Lex I already use the Clean My Mac and since the first time I delete a lot of things I don't even remember how many. Should I format my drive?
About the iCleanMemory so the system will clear the RAM by it self or should I do something different or use another program?
