NETserver, mDNSResponder, syslogd using up large processing power, why?

Hello,
For the past few weeks I've noticed about 150% processing power being used by three processes continuously. They are NETserver, mDNSResponder, and syslogd. They are using only 2 to 3 Mb of memory each but they keep the machine running hot and the fans going louder. I have rebooted and they go away for a while but then soon start up again. I did not notice this when I was running 10.6 and it seems to have started soon after I upgraded to 10.6.1. I have an 8 core Mac Pro.
I read somewhere that Back to my Mac may be a culprit. I've rebooted the machine after turning that off to no avail.
Any other advice? Anyone else having this problem.
Thanks.

I'm having the same problem. The NETserver process is consuming 70% of my CPU and has been for hours. This is a new development since, I think, I installed the latest patch to snow leopard. For what it's worth, I killed the Netserver process yesterday (via Activity Monitor), and the system continued to work normally. Still, it's annoying.
I see that the process is owned by my user id - not root. So it is likely being launched by something I'm doing, though I don't know what that might be. However, I suspect it could be related to my Brother printer (MFC-490CW). It's a wireless printer/scanner, etc, and my Mac needs to listen for inbound connections from the scanner. I notice this problem seems to occur a few hours after I scan something.
Of course, I could be completely wrong.

When i close firefox it runs in the background consuming noticable processing power.why? and how do i stop it?

This only happens occasionally and the only reason why I found out it was firefox is by opening up task manager and selecting the Processes tab. There is no crash reporter or any thging to say there was a problem just a reduction in speed and performance.

This is generally caused by a problematic add-on. See this article on possible solutions: [[Firefox hangs#w_hang-at-exit]].

Hidden but still using processing power?

Hey,
In some sessions which have lots of tracks I might use the 'hide' function to keep the session tidy - some tracks I don't want to delete completely.
What I would like to know is this...
If the tracks are muted / plugins bypassed / instruments bypassed, does this then make them properly inactive and therefore, not using any RAM/processing power?
Fro example, when you do this in Pro Tools, it cuts it out of the equation completely, so to speak.
Cheers!

In Logic 6 and 7, you could go right to what is now called the Inspector, and where it said "inst 01", you could select "off".
This unloaded the instrument from RAM. What was REALLY useful though, is if you had gotten further along in your arrangement, and needed to adjust your MIDI part, you could simply go to where it said "off", and select "Inst 01" again. This would not only reload the instrument that was in there, but it even remembered modifications done to a preset (that hadn't necessarily been saved under a new name, like adjusting the decay of a patch).
This functionality, whether intended or not, was eliminated in Logic 8. It is sorely missed...
The only work around I know of, is to save channel strips that are song specific (as to not clutter up your library)

Syslogd using 100% CPU logging mDNSResponder error

Hi, I have a Mac Mini (2GHz Core 2 Duo, 4GB ram and Lion 10.7.3) that I'm using as a server and home theater pc. I leave it running 24 hours a day and it hosts a Plex server, Transmission (Bit Torrent client) and time machine backups. I also run an Air Video server and Mobile Mouse Pro server (for control using my iPhone). Lately the machine has slowed to a crawl making it completely unusable until I reboot. After a reboot, it will run fine for a few days then slow again. In activity moniter, I can see syslogd using 100% of the cpu. From what I understand, syslogd is the error reporting function in the console. When I check the console, I see this message spamming 500+ times every second:
1/28/12 2:06:35.025 PM mDNSResponder: mDNS_Deregister_internal: 21 6.8.0.E.D.5.E.F.F.F.A.C.5.5.A.5.4.3.2.1.1.F.B.2.D.6.8.1.2.0.0.2.ip6.arpa. PTR Apple-TV-2116.local. already marked kDNSRecordTypeDeregistering
1/28/12 2:06:35.025 PM mDNSResponder: *** process 14 exceeded 500 log message per second limit - remaining messages this second discarded ***
From what I understand, mDNSResponder is related to Bonjour and can be disabled but this is the one machine on the network that I actually want Bonjour enabled (screen sharing and transmission web ui). I have four other Macs on the network and this is the only one having this problem. I also have a jailbroken AppleTV on the network that runs a Plex client to watch my content on the other TV in the house. If I unplug the AppleTV during the slow down, it doesn't stop the spamming. I also wonder about calling it "Apple-TV-2116.local" in the console because when I ssh into the AppleTV to update apps, it's address is simply "Apple-TV.local".
I disabled sleep on the AppleTV because I thought it was getting a new address/ip everytime it woke but that hasn't stopped the issue. I googled the error and only found one other forum post regarding the issue and there was no solution. I'm tempted to take the AppleTV off the network for a week to see if that resolves the issue but it does get used fairly often and none of the other macs on the network are having problems so I think it's something specific to my mac mini.
Thanks!

I am also seeing this problem, as of installing the brand new Apple TV. My mac mini running 10.7 gets rate limited syslog entries, with each of mDNSresponder and syslogd taking a core, hummm....

Killing off mDNSResponder stops it, for a while. I don't know what causes it to start up again. I'd love a solution, as it looks like a bug with mDNSResponder itself, rather than a configuration issue with my mac, apple tv, or network.
Both are very plain vanilla from a config and software standpoint (no jail breaking, haxoring, etc) and updated to current versions of soft/firmware.
I don't want to disable Bonjour, I use it. Obviously the problem is related to the Apple TV device, but according to the message above, there is some sort of internal argument about whether or not an IP v6 addr is in the correct state/workflow. Whatevs. I could probably disable ipv6 and forget it, but that's not really a fix, more of a field dressing. At this point, IPv6 needs to work, bonjour needs to work, even with a misbehaving device.
Looking at the responses I'm not seeing that a community response is likely on this obscure little corner of tech. So, what next?

Can i use a g3 imac for extra processing power

hello, can i use an imca g3 graphite to supplement by g5 1.6 model. if so, how? i am using logic and am running into serious processing problems....is there anything i can do to make sure i am using the processing power of the g5 to the max?
thaqnks

First and foremost, make sure that Logic (and the 3rd party stuff) are the only thngs running on your desktop (ie, no Dashboard apps in the background, no iTunes, no iPhoto, etc, etc).
Second, when you do use a 3rd party plug in, make it sound as close to accurate as you want, then bounce that track and reimport it as a plain audio track (much less processing power need to play the audio track than to apply effects in real time). You can always go back and fine tune later.
Third, Sculpture and Sound Designer are HUGE CPU hogs. Use them sparingly or in the case of Sculpture, bounce the track or freeze it.
Those will release a lot of processor cycles and move you on your way to better performance from your machine.
Good Luck!

Computer processing power used by Apple mobile device

In July I downloaded a new itunes version. Afterwards, whenever I srated my computer, the processing power was being used up by "Apple mobile device" on my task manager. I had to end the process inorder to use my computer. I reinstalled itunes, which cured the problem. However I had a real player update two days ago which has caused the same problem to reoccur. Any solutions/suggestions please?

First, did you use Setup or Migration Assistant? That can happen when coming from a PowerMac or sometimes even from another (Intel) Mac.
Second, wait for the next version of Final Cut due very soon to ship (may have to wait for the ".1" of course to clean up any early issues.

ITunes 11.3 spawns Distnoted daemon which uses all processing power on MacBook Air

Since upgrading to iTunes 11.3 on my work MacBook Air (11 inch, Mid-2013), whenever I run the programme it spawns multiple Distnoted daemons which run up to 250% or more of processing power. I'm assuming this includes multiple threads, given the size of the number.
As a result of this, the computer gets very hot, and therefore I can't actually use iTunes for more than about 15 minutes - quitting iTunes solves the issue, though it normally takes the MacBook a good long time to cool down.
This is, I note, an issue which has occurred before in Windows versions of iTunes, but I couldn't find any Mac-related issues on the discussions forum, so I wonder if it's a bug in 11.3 or the current version of Distnoted? Either way, it's pretty intolerable.

I can't tell much from that. In general, a runaway distnoted process correlates with a failing storage device, but there could be other reasons for it that I don't know about. You might be able to find out more by following the instructions below, but only do so if you feel comfortable with them.
Back up all data.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Please triple-click anywhere in the line below on this page to select it:
sudo touch /var/log/do_dnserver_log; sudo chmod a+rw $_
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. You'll be prompted for your login password. Nothing will be displayed when you type it. Type carefully and then press return. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. You don't need to post the warning.
If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.
Wait for a new line ending in a dollar sign ($) to appear below what you entered. You can then quit Terminal.
After the next episode, open the log do_dnserver_log in Console and post the last couple of dozen lines, if any.
After that, you should delete the log file by dragging it to the Trash in the Finder. You'll be prompted for your administrator password.

Time Machine uses huge amount of processing power

When TM decides to do an incremental backup, the backupd process ***** up a huge amount of my processing power, typically upwards of 45%, causing severe delays and slowdown. Sometimes it's doing it in conjunction with mdworker, but not usually. Is there a way to make Time Machine less processor-intensive? It's really obnoxious.

I have not noticed that, but it takes less than a minute on my machine, so I may have missed it.
If you have a slow processor, it will certainly make a bigger "dent" on your system, but then, so does any major app or file transfer.
I suppose it would be possible to give it higher positive nice level.

PE's processing power compared to Premiere Pro CS6

I'm about to upgrade from Premiere Elements 4 and get a new Windows computer specifically for video editing. I'm happy with PE’s editing features, but the editing and burning process is much too slow. I’m sure a faster processor, more RAM, and better video card would help. Since I’m upgrading for speed, I’ve done a little research and found out about Pro’s Mercury Playback Engine, CUDA processing (with the right graphics card), and even read about the benefits of a Solid State hard drive. Before investing in all that expensive hardware, I’d like to know how PE’s processing and encoding system compares to that of Premiere Pro CS6. With optimal systems for each program, how does their processing power translate into length of time to encode per minute of video? Unless Pro is a whole lot faster, I don't think I can justify the extra expense for the software and hardware.
I understand PE 11 can run as a 64 bit application, but is it multithreaded? I've looked at the system requirements for PE 11, but I think what is listed is the minimum--what are the maximum specs without going over what it's capable of utilizing? Thanks for providing the information that will help me decide how much upgrading to do.

PPro makes use of the (more expensive) CUDA cores in an nVidia card... PreElements does not, so an ATI card works just fine... at least 512Meg of video ram, or 1Gig if you edit large pictures with Photoshop or Photoshop Elements (my thoughts on video ram, not official specifications)

Selected Track Getting More Processing Power?

Hello,
If I understand correctly, Logic 9 allocates more resources to a selected track than other tracks (if you have more than one). Could anyone elaborate on how this is implemented? Can I choose to turn off this feature and give the same processing power to all tracks/plugins?
The reason I ask this is because my Korg M3 plug-in is not playing nice with Logic when the VI track with that particular plugin is not selected. If i select another track, the playback becomes out of sync with the rest of the project. However, if I select that track, everything is played back in time.

It's never been a problem for me before either. It's just with this one plug-in. Like the delay compensation isn't working on it,
that perhaps it's an issue with logic and this particular implementation of 'virtualized' hardware.
Ok, well it's true that Logic functions differently than most (if not all) other DAWS regarding it's handling of buffers. Most DAWs keep a Plugin or VI partially active when the sequencer is stopped. Logic does not, this is how Logic gets it's high efficiency rating, you can load up a project template with all of the plugins & VIs you would need to start a large project and there will be virtually no CPU resources used, as long as you have enough memory you're good to go.
When you keep a plugin track selected... it is active or partially active, this allows the plug-in to initialize and clear it's buffers.
It sounds like the Korg plugin is built on an older AU spec, since Logic does not keep plugins active it's now up to the plugin to initialize and clear it's own buffers when the sequencer is stopped, this means that they have to remain active for a time after Logic is stopped.
A couple of developers I beta tested for cried foul because they learned about this after the plugins had been developed and tested as the original AU spec did not contain this information.
Anyway, it sounds like it will be up to Korg to update the plugin to be compatible with Logic. The scenario you've described sounds like the Korg's buffers have not emptied or the plugin doesn't initialize unless the track is selected.

Mail is using 100% CPU processes - wondering if I possibly have the answer?

Hi...
I have a big problem with Mail using all the CPU processes but may just have found a possible solution. I'm posting to see if anyone else shares this problem or can shed some light on whether or not this is a possible solution.
_*The Problem*_
Over the past couple of weeks, I've noticed that Mail is using on average 100% of the processes and sometimes up to 168% (I have screenshots to prove it). My 17" MacBookPro gets very, very hot and the fans spin up to cool it down so it's obviously not right as it's never done this before. I can only use Mail intermittently now as the machine overheats quickly soon after Mail starts up. As a result, the CPU is being hammered so I can't now use Mail or other CPU intensive applications properly, which is a big problem.
I've used the iStatPro widget to verify that Mail is constantly using 100% of the CPU processes. I've also verified this using Utilities / Activity Monitor. When the Activity Monitor application loads, I've selected Mail from the list of Process Names and then clicked Inspect. I've managed to identify the parent process as being launchd (110) which is using all the CPU power. Here are some other stats for this parent process:
%CPU 95.56 (at that specific instance)
Threads 15
Ports 275
CPU Time 3:30.55
Context Switches 310968
Faults 65795
Page Ins 1
Mach Messages In 272627
Mach Messages Out 65025
Mach System Calls 1459878
Unix System Calls 103120
I guess the important bit is the first bit that says 95.56%.
I have screenshots to back this up but no way of posting them here. I have also managed to use Activity Monitor to generate sample data that the process is creating and again there is no way of posting an attachment here but there is lots of sample data from the process to look at. I've compared the sample data from my MacBookPro to a colleagues machine and the difference between the sample data is enormous. There is obviously something very wrong happening.
Here's some basic info about my machine, with the serial number removed:

_*The Possible Solution??*_
I recently installed a Beta version of Daylite 3 as I was interested in the application and remembered that it integrates closely with Mail. I wondered if Daylite was constantly trying to communicate with Mail and having problems. Having uninstalled Daylite 3, the problem of Mail using all the processes has so far not reappeared. Mail is now using very little of the CPU processes as is usual. However, I'm currently at home instead of on my network at the office so I'll wait to see if the problem still fails to appear when at work.
I know other people have had problems with Mail using 100% of the processes. Have you also installed Daylite 3? There has been some talk of Flip4Mac being a possible culprit but I use Flip4Mac and haven't previously had the problem. The only recent change and connection I can think of is an install of Daylite 3.
I don't want to talk down Daylite 3 but it's the only thing I can think of and having uninstalled it, the problem hasn't occurred. I hope I have stumbled across the solution but any thoughts, shared experiences or feedback would be greatly appreciated...
Many Thanks,
Nigel

Hi...
Thanks for the post. Not sure what you mean when you say "What does Mail say it's doing?" Can you be more specific and supply specific instructions to follow so that I can give you the information you need?
I've sampled the process but can't post any attachments on the forum. I've listed what the Activity Monitor stats are saying at the top level in the post above.
This is a serious problem that's hammering my machine and making it overheat and almost making it unusable. Any feedback or instructions anyone can give me for what info to supply to help you determine what the issue is would be greatly appreciated. I'm hoping to find a solution here rather than have the machine overheat permanently and eventually fail, leaving me to sort it out with AppleCare.
Help!

How much ram and processing power in my imac will meet my graphic design needs?

Hi,
I'm in the market for a new imac. I'm trying to figure out how much ram I'll need and which processor will be sufficient for my graphic design needs.
I'm gonna need it to be robust enough to have InDesign, Photoshop, and Illustrator open at once along with spotify, safari with many tabs open, and a couple other apps including evernote and game from time to time. Also, I'm gonna be managing a good deal of fonts in font explorer. How much ram and processing power will I need in my imac to keep everything snappy with all these apps going at the same time?
Any advice on this would be much appreciated. Feel free to include any other relevant information you think I should know.
Thanks, Nick

Computers are out of date when you open the box
Ok, getting serious, that iMac should be a viable workhorse for what you want for a good five years, and taht depends on how much ram you put in it, add really fast external storage, and so on.
Didn't throw this in earlier so as to not influence the discussion: my daughter is the senior art director, VP, at a graphics design firm in NYC. Has been in the business for a number of years. When she changed out her Mac at work, bought, or company bought, the 27" iMac model just before the latest, with maxed out CPU/GPU, and storage. They maxed the memory to 32 GB for her, then added a 30" Apple cinema display so she has almost 5' of display in front of her. There is nothing she cannot have open all spread across that display area. She works almost exclusively in print media, occassionally condescends to do web stuff. And has a massive array of RAID drives hanging on it. But that is a setup an individual would be hard pressed to go with.
At home she uses a MacBook Pro with top cpu and display but that is all.
The point, just how massive do you want to go depends on how fast you have to work; in the office where time is money you need tons of horsepower. At home, you scale it to your abilitty to juggle other tasks at the same time.
I think your choices have been great, the discussion has focused on what is important and especially what can and cannot be changed in the future.
Best of luck setting this up.

Greetings from a Photoshop Newbie. I need a computer, preferably a Mac laptop, with some serious processing power. I take photos with a Pentax 645Z; files are 50MB raw. I upload from Adobe Bridge and manipulate the photo, sometimes turning them into files

Greetings from a Photoshop Newbie. I need a computer, preferably a Mac laptop, with some serious processing power. I take photos with a Pentax 645Z; files are 50MB raw. I upload from Adobe Bridge and manipulate the photo, sometimes turning them into files in excess of 250MB. I cannot resize as the large files are needed for enlargements. Have all sorts of problems trying to manipulate, add effects and saving most large files. I need some serious processing power. Can anyone suggest what Mac i should purchase? I thank you in advance for your help :-)

It sounds as if you're having some system-related problems now, unrelated to processing power as such. In particular, a buggy video driver can cause everything to slow to a crawl.
Medium format files are big, true, but not so big as to cause significant slowdowns on a normally functioning and reasonably current computer. A laptop will always be slower than a well-equipped desktop system, though. Mac vs PC plays no part in this, performance is unrelated to platform.
Bottlenecks are different in ACR and Photoshop, so that should give you a clue. ACR is computing-intensive and mostly limited by CPU speed. Photoshop, however, is mostly bandwidth-intensive and mainly limited by memory and disk throughput. It's also sensitive to GPU issues.

Why can't I make Lightroom use all the CPU-Power (all cores) available for generating Previews?

Dear Lightroom Team,
I've been a Lightroom user since the very first Beta, and I am truly happy with the work you deliver. It changed my way of editing forever, and you guys keep improving it.
Yet there is that one question that bothers me, and that i'm looking for an answer for.
My Workflow has the generate Previews checkbox checked by standard. I usually import between 150 and 2000 photos at once, on occaions it can be up to 5000 photos. Generating Previews always takes a significant amount of time, and Lightroom is only using 25% of my CPU Power while doing so. (using a MacBook Pro 8,2)
I understand the concept, that only using 25% CPU enables me to use the computer while waiting for the Previews. But most of the time I just grab myself a cup of coffee, do the dishes or other stuff, while waiting for the Previews. Usually I rund out of things to do, because it takes ages to Process all the photos. So I would really love to make Lightroom use ALL the cpu power possible.
I'm sure you guys have spent a lot of thoughts while coding this and have a very good answer handy. Looking forward reading it!
all the best,
Wolfgang

On my four-year old Windows 7 i7-860 system LR4.4.1 takes ~0.5 sec. per Canon 5D MKII 21Mp raw image to render 'Standard-Sized' previews with LR Catalog Settings 'Standard Preview Size' set to '2048' pixels. I consider that pretty fast!
I usually build 1:1 full-size previews on import, which takes ~5.0 sec. per image. Processor utilization varies between 15-50% for Standard-Sized previews and 15-65% for 1:1 previews. I consider this pretty slow, but it doesn't stop me from working on the images inside LR's Library and Develop modules.
I wait until 'Copy and import photos' has completed and can see Preview Building has started. LR doesn't slow-down much even with the 1:1 preview building going on in the background. Have you tried working in LR during the preview building (i.e. sorting, rating, keywording, and Develop adjustments)?
