Lightroom 4.1 CPU Spiking

I am running OXS with 8gb RAM and two 2.26 Quad Zeons. I am experiencing HEAVY spiking in CPU utilization, upwards of 800% even when making small adjustments such as reducing the blacks by ONE increment. I am now running of an exported catalog with about 15 images w/ previews. Both the cat and images are on the same HDD as lightroom is installed on....WTF is going on. Never used to be this slow.
Write xmp data is off.
appreciate any help!
thanks

HI,
LR is optmized to render only the pixels that are displayed on you screen. Did you screen resolution changed? One of these 2500x1xxx monitors?

Help. Digital noise and CPU spiking constantly.

Hello,
Ever since I got the latest software update I've been having serious issues. Anytime I try to play a software instrument in Logic Pro 8 or Mainstage I get hellish digital pops and clicks and the CPU spikes up constantly. An error message says there's a conflict with a third party midi driver. I've deleted every suspect midi driver I can find. I tried everything in the trouble shooting guide short of reloading Logic but nothing's worked. I've just been using the built in audio card and it worked great up till this point.
Any ideas? Can I role back the update? I can't seem to find how to do it.
Thanks

Apple released a Macbook Pro firmware update yesterday.
This firmware update appears to have fixed the large CPU spikes in Apple Logic Pro that began after the last recent Airport software update. Previously, when running Apple Logic Pro even with a small # of tracks with the Airport enabled there was digital noise and one of the CPU peaking very frequently. In order to record or play back with out these issues the only solution was to turn off the Airport. Since I installed the firmware update I have used Logic Pro extensively yesterday recording and playing back projects that previously had this issue and did not have the CPU spiking or digital artifacts.
Thank you Apple!

Lightroom 6 high CPU usage

Anyone else seeing very high (300-400%) CPU usage in Lightroom 6 - when it's apparently not doing anything?

Odds are it is doing something in the background. Perhaps you have some photos synced in LR Mobile that are being converted to smart previews and uploaded, or maybe you recently switched on facial recognition and LR is busily indexing all of your images? Check in the activity centre to see if anything's happening there.

HT3161 I have a 27" mac running with a 3.4 ghz core i7 and 16 gigs of ram and using the latest logic. I have a composition consisting of 7 audio tracks and 4 software instruments and 4 plugins on 4 tracks so why is my CPU spiking ?

I'm running a 27" imac with a 3.4ghz core i7 processor and 16 gb of ram.... In logic I have a project with 7 audio tracks with various plugins running and 4 software instruments which incidentally are not playing all the way through the track...my CPU spikes even if the project is paused...why is this happening on such a high end machine.....wasting my money again seems to spring to mind !!

Did you read this support article?
http://support.apple.com/kb/ht3161

Logic Sputtering, CPU spiking horribly for no apparent reason, gives MIDI sync error even though the computer is set at the same sample rate.

It's literally making it impossible for me to produce anything, after what seems an arbitrary amount of time in Logic my audio will begin to distort and I will get errors stating that my MIDI sample rates don't match, but they DO and it will spit out some seemingly random sample rate from nowhere. My CPU usage will spike and even my cursor will jitter across the screen until it stops stuttering. The audio problem seems to only be caused by Logic but will sometimes continue to occur in other applications after Logic is closed.
How on earth do I fix this? It's making it impossible for me to work on remixes that I have to have finished soon, I have deadlines and I simply can't work in these conditions... the audio doesn't work.

That sample rate error comes up when Logic gets out of sync internally, you will sometimes also see a MIDI/Audio sync error. MIDI timing is taken from the audio driver/sample rate, it's what enables MIDI to stay in sync with audio, when the audio/MIDI engines get out of whack these are the kind of errors that pop up. (there doesn't have to be any MIDI in the song) Can be caused by bad drivers, interference from another running program, synchronization settings, bad or incompatible plugins!

Why is my CPU spiking, causing the desktop to reboot every few seconds?

I watch the CPU reading in the Disk Monitor spike in usage (from about 5% to 100%) every 30-90 seconds. Every time it does, the desktop reboots, taking me away from whatever program I am using to the Finder. What should I do?

T43 running hot. CPU spiking to100% - WinXP Pro

I am not able to access the default image on the T43. It may have been modified for no access by our corporate office.
What (hopefully free) software I may use to run diagnostics on all the hardware including the fan and software like the BIOS, if possible?
Thank you.

Hi cstech, welcome to the forum.
It is not unknown for T43s to get little warm and for the fan to run constantly. I believe sometimes that my T43p has an internal hairdryer.
As far as diagnosis software goes, you could try PC Doctor on a bootable cd. (As long as youcan change the boot order using F12) or for W2K / XP.
Regards

Lightroom Mobile Sync - Extremely High CPU Usage/Sync Process Causes LR To Lag

Since my other thread doesn't seem to be getting any responses, I'm pasting what I've found here. Please keep in mind I am not a beginner with Lightroom and consider myself very familiar with Lightroom's features excluding the new mobile sync.
1st message:
I'm on Lr 5.5 and using the 30 day trial of Adobe CC to try syncing one collection of slight more than 1000 images. Despite already having generated the Smart Previews, I can see my CPU crunching through image after image (the rolling hills pattern in the task manager) while doing the sync. I was assuming, since I already created the Smart Previews, that the sync of this collection would begin immediately and be done by simply uploading all of the existing Smart Previews. The Smart Previews folder of the catalog is 871MB and has stayed the same despite the CPU obviously doing *something*. As it is now, the sync progress is incredibly slow, almost at a pace like it's actually exporting full-res JPGs from the RAW images (as a comparison only, I know this should not be what it's actually doing).
Another side effect of this is that I'm basically unable to use my computer for other tasks due to the high CPU utilization.
Win 7 x64 / Lightroom 5.5
Intel i5 2500k OC'd 4.5GHz
16GB RAM
SSD for OS, separate SSD for working catalog and files
2nd message:
As a follow up, now Lightroom thinks all 1026 photos are synced (as shown in "All Sync Photographs" portion of the Catalog though all images after the 832nd image show the sync icon per image stuck at "Building Previews for Lightroom Mobile" and the status at the top left corner has been stuck at "Syncing 194 photos" for over 12 hours. Is there no option to force another sync via Lightroom Desktop and also force the iOS app to manually refresh (perhaps by pulling down on the collections view, like refreshing via the Mail app)?
3rd message:
One more update, I went into Preferences and deleted all mobile data, which automatically signed me out of Adobe CC and then I signed back in. Please keep in mind the Smart Previews were long generated before even starting the trial, and I also manually generated them again (it ran through quickly since it found they were already generated) many times. Now that I'm re-syncing my collection of 1026 images, I can clearly see Lightroom using the CPU to regenerate the Smart Previews which already exist. I have no idea why it's doing this except that it's making the process of uploading the Smart Previews extremely slow. I hope this time around it will at least sync all 1026 images to the cloud.
4th message:
All 1026 images synced just fine and I could run through my culling workflow on the iPad/iPhone perfectly. Now I'm on a new catalog (my current workflow unfortunately uses one catalog per event) and I see the same problem: Smart Previews already generated but when syncing, Lightroom seems to re-generate them again anyway (or take up a lot of CPU simply to upload the existing Smart Previews). Can anyone else chime in on what their CPU utilization is like during the sync process when Smart Previews are already created?
New information:
Now I'm editing a catalog of images that is synced to Lightroom Mobile and notice that my workflow has gotten even slower between photos (relative to what it was before, this is not a discussion about how fast/slow LR should perform). Obviously Lightroom is syncing the edited settings to the cloud, but I can see my CPU running intensively (all 4 cores) on every image I edit and the CPU utilization graph looks different than before I started using LR mobile sync. It still feels like every change isn't simply syncing an SQLite database change but re-generating a Smart Preview to go with it (I'm not saying this is definitely what's happening, but something is intensively using the CPU that wasn't prior to using LR Mobile).
For example: I only update the tint +5 on an image. I see the CPU spike up to around 30-40%, then falls back down, then back up to 100%, then back down to another smaller spike while Lightroom says "Syncing 1 photo". I've attached a screenshot of my CPU graph when doing this edit on just one image. During this entire time, if I try to move onto edit another image, the program is noticeably slower to respond than it was prior to using LR mobile, due to the fact that there appear to be much more CPU intensive tasks running to sync the previous edit. This is proven by un-syncing the collection and immediately the lag goes away.
I'd be happy to test/try anything you have in mind, because it's my understanding that re-syncing photos that are edited that are already in the cloud should be simply updating the database file rather than require regenerating any Smart Previews or other image data. If indeed that's what it should be doing, then some other portion of LR is causing massive CPU usage. If this continues, I will probably not choose to proceed with a subscription despite the fact that i think LR mobile adds a lot of value and boosts my workflow significantly if it wasn't causing the program to lag so badly in the process.
I know this message was incredibly long and probably tedious to read through so thanks in advance to anyone who gets through it
-Jeff

Thanks for reporting. Just passed along your info to some of our devs. One of the things that needs to be created (beside smart previews) during an initial sync are thumbnails + previews for the LrM app - Guido
Hi Guido,
Thanks for pointing this out. I realized the same thing when I tried syncing a collection for offline mode and found out the required space sounded more like Previews + Smart Previews rather than just the Smart Previews.
greule wrote:
Hi Jeff, are your images particularly large or do you make a lot of changes which you save to the original file as part of your workflow?
The CPU usage is almost certainly from us uploading JPEG previews not the Smart Previews - particularly during develop edits as these force new JPEG previews to be sent from Lightroom desktop, but would not force new Smart Previews (unless the develop edits are modifying the original file making us think the Smart Preview is out of date) to be sent.
Guido
My images are full-resolution ~22mp Canon 5D Mark III RAW files so they're fairly large. Even if I only make one basic change such as exposure changes, I saw the issue. By "save to the original file" I'm assuming metadata changes such as timestamps, otherwise edits to the images aren't actually written to the original file. I'm only doing develop module edits so I shouldn't be touching the original file at all at this point in my workflow.
I think it makes sense now that you mention that new JPEG previews need to be generated and sent to the cloud due to updated develop edits. My concern is that this seems to be done in real-time as opposed to how Lightroom Desktop works (which is to render a new Standard Preview or 1:1 Preview on demand, which means only one is being rendered at any given time while viewing it in Loupe View or possibly 2 in Compare View). If I edit, for example, 10 images quickly in a row, once the sync kicks in a few seconds later, editing the 11th image is severely hindered due to the previous 10 images' JPEG previews being rendered and sync'd to the cloud (I'm assuming the upload portion doesn't take much CPU, but the JPEG render will utilize CPU resources to the fullest if it can). Rendering Standard/1:1 Previews locally and being able to walk away while the process finishes works because it is at the start of my workflow, but having to deal with on-the-fly preview rendering while I'm editing greatly impacts my ability to edit. Perhaps there can be a way to limit max CPU utilization for background sync tasks?
It may help to know that I'm running a dual-monitor setup, with Lightroom on a 27" 2560x1440 display maximized to fit the display (2nd display not running LR's 2nd monitor). Since I'm using a retina iPad, the optimal Standard Previews resolution should be the same at 2880 pixels.
Thanks again for the help!

In-place update of web service causes CPU spike

I've done many in-place updates of my production service with no issues. Today when I ran an update the CPU spiked on both instances to around 99.6% for almost an hour. The CPU eventually came down to its normal range while under the expected load from the
service. I didn't see any requests fail, but response times were up significantly.
I ran another in-place update later in the day and the same thing happened again. Currently my production service is pegged at over 99% for over an hour. Thankfully this is a slow time for the service, otherwise this could be a real mess for me.
Before each in-place update I deploy to the staging environment and everything is working as expected (there's nothing on the staging environment before as I delete it every time the production environment is successfully updated). As a test I did the same
in-place update on the staging environment and that environment has been at 50% utilization for an hour now. It starts as soon as the update takes effect for each instance (one instance pegs a couple minutes before the other).
I have profiling turned on for this service, and when I go to look at the profiling report I generally get these messages:
5:51:24 PM - Connecting to the Profiling agent on the VM instance
5:51:27 PM - The Profiling agent is preparing to process the request
5:51:28 PM - Preparing the Profiling logs on the VM instance
5:51:42 PM - Uploading the logs from the VM instance to the Windows Azure storage account.
5:51:43 PM - Profiling log request failed. Details: Profiling agent failed to upload log snapshot to Windows Azure storage account.
I'm not sure if it's related to profiling or not, but I'm wondering if there is something broken with the in-place update process in Azure?
Any help is appreciated.

As further investigation I deleted the staging environment, re-deployed to it, and that worked just fine, CPU levels were normal. I did the VIP swap, and my production environment is back to normal.
The staging environment (old production env) continued on it's spike for one of the instances. I checked and the instance that isn't spiked is the one I successfully got a profiling report on. I'm going to wait an hour or so and run a profiling report on
the other instance to see if that also gets the instance back to normal CPU times.

CPU 100% seeing HPMSN083.DLL (runapp.dll)

We installed several HP laserjet p1606 printers on our print server and now we're seeing the CPU spiking at 100% and drilling into it we see HPMSN083.DLL!MonitorPrintJobStatusW+02...
When we kill it is kills the print spooler. What is this and how do we get rid of it? We disabled the status message in the printer properties (Properties/Device Settings) and it still spikes and kills the print server and no one can print.

Hi Phil
It worked with stdcall (WINAPI) selected!! Thank you so much.
Also, your original comment about 100% CPU use reminds my ...
I was building an industrial control system around a set of GPIB
instruments and needed a single switch input to the program. I
used the (old fashioned) joystick port switch, on the assumption that
this had hardware interrupts and would be essentially invisible to the
processor. This worked well. The program is still working
after 2 years and > 60,000 tests
The second model had a PC without a joystick, so I hacked a really
cheap USB joystick for the same function. While it worked, it
appeared that the processor was very busy and was not running my
program as it should. The joystick regularly disappeared and
required re-inserting. I gave up and used a digital line in on
the NI card that we then purchased, with no problems. I didn't
investigate at the time but maybe the USB interface was gobbling up the
processor time.
I will need to consider this with the Velleman card.
Cheers and thanks again.

CPU 100% 20 seconds into every song

It may or may not be iTunes's fault, but I'm just making sure if anyone else is having similar problems.
About 20 seconds into every song, CPU usage skyrockets to 100%, and all I can do is wait until the CPU usage drops back down a few seconds later. Then the song continues just fine until 20 seconds into the next song.
I'm using iTunes 5 on Windows XP Pro, Service Pack 2, (256 MB RAM), and I have SoundMax Integrated Digital Audio (which I believe is onboard sound for my Intel Desktop Board D845PESV.)
Any ideas?

I'm having the same problem. I've isolated it in a number of ways trying to resolve it.
It always happens 13 seconds into playing a track. This applies whether it plays from the beginning, 1 min into the track or if I make is jump to different places. Each time, once it has played 13 seconds (ie first 13 secs or if I jump to 1 min immediately it will be at 1:13 or if I play 6 secs then jump to 1:30 it will happen at 1:37). The CPU spikes to 100%, pausing everything and leaving a 3 or 4 sec silence.
This happens regardless of track length. So a 1 hour dj set will have the CPU spike at 13 secs and then be fine for the next hour.
It seems to me to be related to some sort of buffering or something similar in Itunes. I have worked out that once it has caused the CPU spike I can restart the same track and it will play through without a hiccup. If I play the next track and then come back to the first track, though, it will glitch at 13 secs again. I can also make it glitch on a replay of the first track without playing any others by changing the tracks that are to come after it in the playlist. This seems to suggest it is related to buffering the coming track(s).
I can make the silent gaps go away by reducing the size of my music library considerably. It is over 45 gig now. If I reduce it to below 20 gig the CPU spiking occurs but not at 100% and so not causing the silences. The problems is still there, though, and itunes has played my 40 gig library fine for months without any such problems.
Recent changes have included a few software installs. I have removed those that I could (eg Nero) but I do still have one photo editing programme that I need for a current job. I had removed quicktime from my startup but seeing a suggestion that this caused such a problem I have put it back. This has not fixed the problem for me.
I have also bought a shuffle and would have probably run the software related to that. If you had a problem when you added a mini perhaps it's due to some sort of error arising from the software coming with new ipods when used with existing itunes installations? Just a guess.
I'm running Itunes 4.7.1.30
If anyone can help with this I would be most grateful as it is making Itunes unusable on my computer. I'm going to have to go back to playing cds!!!

CPU Usage Spikes - Crashes ITunes

I've been using Itunes for about a year, and over the past week, my CPU usage will spike at 100% while playing Itunes, causing the song quality to skip and play as if it was a scratched CD. I updated from 4.9 to 5.0 (erasing all existing Itunes programs first) and the problem still happens. I'm not running anything else other than Itunes, and the usage still spikes to 100% causing the problem.

SPAN session CPU usage

Hi,
A while ago we tried doing logging on some ACLs on a 3750X running version 15.02SE. After some time the CPU spiked and caused a memory leak which forced the switch to reboot. I did some reading and found that the CPU usage does spike when logging on ACLs, there are ways to rate limit the logging but that doesn't give full visibility into what is going through the switch.
I'm guessing the alternative is running a monitoring session.
My question about the SPAN session is, will it greatly impact the CPU of the switch the same way ACL logging did? And if so, will monitoring 10 Vlans in both directions and sending them to a single destination cause the same type of crash as we experienced with ACL logging?
If we can do the monitoring sessions, it would be a good workaround seeing as the logging interval will give us limited visibility.
Cheers,
Waqas

Why do you need three different browsers running at the same time? Maybe that's causing a problem or what your are doing with them.
Suppose you create a new user account and log into that account. Does this problem persist? If not then you have a problem with file corruption in your account. Could be preference files for the browsers, could be caches, could be both.
