Lightroom 3.3 Performance Feedback

Please use this discussion topic for your feedback on Lightroom 3.3 RC and the final Lightroom 3.3 release when it becomes available.  The Lightroom team has tried very hard to extract useful feedback from the following discussion topic but due to the length and amount of chatter we need to start a new, more focused thread.  Please post specifics about your experience and be sure to include information about your hardware configuration.
Regards,
Tom Hogarty
Lightroom Product Manager

Tom,
It may be necessary (reading the trail below) to start another thread entitled - "Definition of a release candidate - discuss..."
I for one had terrible trouble running LR3.0 (the LR3.0RC was fine), so whatever changed between the LR3.0 and the LR3.0 final caused all measure of upset with my image processing on my machine.
I had -
     Video flickering - particularly when moving from library to develop with large tiff's (80MB) selected
     Very slow rendering
     Adjustment brush very slow to update, causing over runs while using it
     Random lock-ups and reboots
Since the upgrade to LR3.2 things are better, I get the occassional flicker, rendering is still slow, as is the adjustment brush but the occasional lock up's seem to have disappeared.
I'm running Windows 7 ultimate, 4GB Ram, AMD Athlon dual core and have lightroom loaded in 64 bit mode.
If you want to know anything about my hardware, drivers, set up or otherwise, just e-mail me. I have not updated to LR3.3RC yet as I believe it cannot run alongside LR3.2 on a windows machine.
Best Regards
Phil

  • [Consolidation-Locked] Lightroom 4.1 Performance

    hello my lightroom 4.1 copy is so slow, in the develop module when switching between raw files the "loading" logo keeps spinning for a long time before I can edit the file, and the same happens when I click on the image to zoom in, takes forever to do so.
    I run windows 7 64 bit
    Xeon 16 core 2.4 gb
    32 gb ram
    the OS and the raw files are on two seperate sata 6 SSD drives
    theres is no way  it should be so slow to simply switch from raw files or zoom in?
    Even in loupe mode when clicking on a file to zoom it takes forever.
    Photoshop cs6 camera raw does not show performance issues, when importing the same raw image in photoshop zooming in is immediate instead of many many seconds in lightroom.
    I tried the optimization suggestion by adobe, setting the camera raw cache to more than 10gb, optimizing the catalog etc... but nothing changes. (http://helpx.adobe.com/lightroom/kb/optimize-performance-lightroom.html)
    If you have any suggestion I am very interested because at the moment it is very frustating to use the software

    Hello All, finished a chat today with Adobe help. Thought I would post this info for those having the same trouble. For reference, my specs for the new machine I built are:
    Win7, 64-bit; 16GB ram; 4-core AMD Phenom processor 3.2 GHz; SSD with Win, Photoshop & LightRoom installed on it; Nvidia GeForce 560 1GB; photos on secondary drive. CS5 12.1x64, LR4.1 CR 7.1
    Installed 4.1 updated viseo drivers, tried all the "remedies" such as enlarging & clearing the cache, etc. Nothing worked. LR was SLOW SLOW, taking 5-9 seconds to be load and accept adjustments each time I selected a new image to adjust (no big deal for 10-20 images, but for 800 image weddings from 2 cameras, quite a long time to wait on the computer!!!) Called Adobe, they said they were aware of performance issues on some machines, and were working on it.
    Got on Adobe chat help today. The following is the conversation, with superfluous comments etc. edited out. The simple procedure sped my LR performance up by at least 60-70% in my estimate. Amen.
    I do not surf the forums, and this is only my second post ever, so please don't expect me to answer questions right away, though I'm sure others will. I am just posting this conversation so that others might try the same, and maybe it will help them. Good luck!
    Help Chat with Adobe's "William", June 11, 2012:

    William: Okay.
    William: Launch Lightroom and check if you're getting the same issue.
    Jojo: that seems to have sped it up significant;y
    William: Perfect.
    William: Please double check if that works fine now.
    Jojo: Much faster, but all of my presets are gone
    Jojo: Export presets, etc
    William: It was due to corrupt preference that was causing this issue.

    William: After that open Preferences folder inside it.
    William: Check for the file "Lightroom 4 Preferences.agprefs" and rename it to "OldLightroom 4 Preferences.agprefs".
    William: Launch Lightroom and check if that works fine for you.
    Jojo: Oh yes, that's working well!
    William: Perfect.
    Jojo: Much better!
    William: You can start working with the product smoothly now.
    William: Great.
    William: I'm happy to help you.
    Jojo: Hey, are they fixing this in a release? I know a lot of photographers who are VERY upset about this performance issue
    Jojo: I was ready to change back to LR3
    William: Corrupt preference may cause Lightroom to work slow.
    William: We renamed the preference file and it is working fine.

  • Poor Lightroom 5.7 Performance when using part repair tool

    Hi Lightroom pros,
    I'm using Lightroom 5.7 for about half a year and are very happy with it. Unless I'm working on photos where I have to use the part repairt tool to much.
    I'm specialized in car photograpy and often have to remove dust from the cars paint work and chrome. When I have to work on hughe areas Lightroom becomes slower and slower. I read that the repair tool costs a lot of performance but I'm wondering if I could optimize something or if there is a workaround for that? Because right now its not usable doing one click and waiting 2 minutes...
    I'm using the newest Lightroom 64-bit version on a Windows 8.1 Enterprise 64-bit Laptop with an internal SSD drive. LR is installed on that drive and the Catalogue also is stored there. I have 70 GB of free space on that drive, my catalogue is around 5 GB, my Camera Raw Cache Size is 20 GB.
    The machine has 16 GB of RAM and an Intel Core i7 3 GHz Quadcore processor. My RAW files are stored on an external USB 3.0 Drive (not SSD).
    When working on that kind of picutres I usually close as much programms as possible, so that most of the time LR is the only working desktop programm. What seems strange to me is, that even if I'm waiting for minutes for LR to answer, that my processor and RAM are only using about 40% of it's power. The rest seems not to be used by LR?!
    I would be really thankful for tipps or ideas how to improve that issue because right now I'm really wasting a lot of time.
    Kind regards
    Torsten

    I guess this depends on what you are doing, what type of original files you are using, and your own perception of quality. I would believe that in most cases, if you do all the editing in LR except for the spot removal, get the photo to appear the way you want (except for the spot removal), and then lastly move it to PSE and remove the spots, that there isn't really any noticeable loss of quality.
    I must admit I'm not a pro concerning color managment. But I already downloaded the PSE testversion and realized that it is not capable to deal with 16-bit color depth. Wouldn't that be noticeable after the finale spot removal step?
    So, you should tell Adobe this, not me. This is a forum for users (like me) to help other users (like you).
    I know. I just wanted to emphasize why switching to PS wouldn't be the perfect solution for me (even if I'm considering it).
    Thanks so far!

  • Lightroom 5.5 Performance is absolutely Unacceptable on OS X Mavericks !!!

    Hi -
    I can officially no longer work in Lightroom.
    I never had problems before on my rMBP with 1GB Graphics and SSD
    After this update everything is going wrong !
    1) Just launching LR 5.5 will make the fans spin @ Maximum (No library open)
    After quitting it will take 5 minutes for the fans to return to normal.... 5 MINUTES
    2) Working with several displays is now impossible. LR is totally confused about which display is main and which is secondary.
    I open a library and click on one image - which randomly will display in display No. 2. Sometimes the main display will take 2 minutes to update to the same image as being
    displayed in the secondary display. Making adjustments will immediately reflect in main display but take minutes to reflect in secondary.
    3) LR cannot remember it own window state when being relaunched.
    When using a secondary display which is set to display, after quitting LR, when relaunched LR will be highly confused which is the secondary display and which is the main.
    This is totally erratic.
    This whole CC 2014 has been the single worst update experience I have EVER had to deal with. It seems to me that adobe's progressive update program has severely compromised its renowned quality standards.
    I have tried to reinstall Lr 5.5, delete and reinstall Cuda, delete all preferences etc etc etc etc... no change.
    LR 5.5 is performing so poorly that one cannot use it anymore !
    If anyone has an idea to what on earth is going on here, I sure would like to hear about it !
    Thanks

    I have since found different system requirements shown on this page:  http://www.adobe.com/products/photoshop-lightroom/tech-specs.html  This one shows that OS 10.7 is required.  Nice that the system requirements shown on the purchasing page are lower than shown on other pages. 

  • Poor Lightroom 4.4 performance when laptop connected to an external monitor

    Hello everyone,
    I have recently purchased an external monitor JUST to be able to edit my photos at a higher resolution (1920*1080). However, Lightroom performance is extremely bad and the sliders and crop tool are all laggy when I just connect the monitor that I have bought . Doing the same task on my laptop monitor takes much less time and runs perfectly smooth (the resolution of the laptop is 1366*768).
    Is this an issue with Lightroom 4.4 or is it my because my laptop is not fast enough?
    Here is some more information about my system specs:
    The Lightroom version is 4.4 and I have a laptop with 8 GB ram, a 2.4 GHz Intel Core i5 CPU, the GPU is Radeon HD 5650.
    My OS is Windows 7 64 bit and the connection to the monitor is via a VGA cable
    I just want to use the external monitor (single display) so I use it as a projector and I do not extend the displays. I just wanted to edit my photos with a higher resolution monitor so that I see the editing flaws in them more easily.
    Please help me if you know how to deal with this because otherwise I have to return the monitor because it's of no use.

    The higher resolution is pushing you to the next higher rendering resolution.  If you are in Develop and set zoom position to 1:4 or 1:8 it should speed back up (each level is 4 times as fast as tge previous).

    hi again Atocruz, have you checked that you are not running any other applications such as Windows Media Player when trying to safely remove the phone? if you have these running then it won't remove safely because the other programs are using the phone processes in the background

  • SQL Developer 2.1 general performance feedback

    After testing 2.1 for several days, there seems to be a performance regression in the general interface. When running migrations, the application becomes generally unresponsive, unless you click the "run in background" button. By unresponsive, I mean that the dialog only intermittently shows updates as to what it's doing, even though work is continuing behind the scenes.
    Also, when running a large script in "execute script" mode (F5), the script output in the lower window lags behind and the actual script window above, where it used to scroll to keep up with the current statement being executed, lags tremendously. Also, the interface is basically unresponsive. Clicking scroll bars doesn't work and the new "ScriptRunner" throbber or cylon scrolling eye thing freezes as well.
    Minor problems, but annoying ones. Everything else is great so far, though. Keep up the fantastic work!

    Have found out that if the data dictinary inquries drop the the SYS qualifier then we can implement the dolution on metalink. Any chance that this alteration can be implemented? At the moment we cannot use the tool as it is causes too many issues.

  • Lightroom 3 poor performance

    I read about all of the improvements that were supposed to be in LR3, but I'm extremely disappointed in the performance of it and Adobe.
    Today I tried to take a simple catalog of jpgs and create a slideshow.  About 3 files into the rendering, LR3 crashed.  OK, so it happens....Restarted everything and bang it happens again even though it got a bit further.  Third time the charm, NO!... just got a little ways into it when the bits started flying.   I checked for updates...no dice.  This is just the latest crash.  I got random crashes just touring myself around in the application the day I downloaded it.  I probably wouldn't be nearly so miffed if I hadn't had to go through h#$% to get the KockAmaymee Download Manger to work....Apparently it's NOT MAC friendly at all..  I actually had to get to a PC to down load the software and transfer it to the MAC (1 year old PowerBook Pro with SnowLeopard and all the updates)...really! what does it take?  So, if you're about to upgrade, before you let Adobe have your $99.00, you might want to consider waiting until they get a stable product on the market.  Oh, yeah and try to find something in the support pages that relates to LR...good luck.

    I have not experienced this.  Is the Library on the MBP?

  • Lightroom 3.3 Performance/Crash Issues

    During the process of tweaking approximately 200 images in Lightroom’s develop module (primarily the Crop, Spot Removal, Camera Calibration and Lens Correction tools) several issues were encountered:
    -         Sluggish cursor response after adjusting ~30 photos
    -         Intermittently having the application enter a ‘No Responding’ state
    -         One occurrence of the ‘An unknown error occurred’ being displayed

  • Lightroom has a hard time with local adjustments:

    Local adjustments: Spotting / Cloning / Healing Brush, Adjustmenst Brush, Graduated filter
    I posted  the piece below as a response to thaehn’s post “Lightroom freezes on Dust Spot Removal” but I thought the topic is important enough to warrant its own post.
    This in advance: I'm running WIN XP SP4 with all available patches; have 4 GB of RAM; have a dual-core processor at 3 GB.
    Apart from my drive C, I have two internal hard drives in Raid 0 configuration (thus they show up as one drive). I also have an external hard drive that's in Raid 1 ( "mirroring') and is connected by fire-wire 400.
    Yes, LR "freezes" when using the dust spot tool and also when using the adjustment brush or - but to a lesser degree - when using the grad filter.
    My observation though is that it's not a true "freezing", because if I wait long enough LR starts working again. So when using these tools, LR gets extremely busy und just doesn't have enough resources left to respond to further commands right away - but it "stores" the comands and acts on them eventually.
    If I turn on my task manager I observe the following when using these tools: the CPU gets extremely busy (i.e. the green bar is at 100%)  while the RAM usage is high but not to the max. The "freezes" occur when and as long the CPU works at 100%. If the CPU is below 100% LR responds sluggish and the response is normal again when eventually the CPU usage is at 0%.
    Also, in my observation, this behaviour of LR is compounding, i.e. the wait-times for my CPU to get back to 0 are increasing, the longer I work with these tools or the more photos I work on. Re-starting LR does not bring change: the behaviour establishes itself when using the tools again. It is as if LR needs to do some work in the background and that this background work piles up the longer I work in LR.
    I am not a software or hardware specialist, so the following observations are somewhat subjective and not really quantifiable.
    In Photoshop I observed a similar behaviour (although never as bad) when working on files of 500 MB and above. It was particularly bad when working on photos residing on my external RAID 1 hard drive. I had a hunch that it might have to do with the reading and writing from a drive that a)  is external and b)  is  in RAID 1. It is known that RAID 1 has slower writing (and also reading) speeds than RAID 0 (or no RAID at all). So in Photoshop I managed to cut down on the unresponsiveness by moving large files to my internal RAID 0 hard drive and working from there.
    From this experience I come to the assumption that some of the "busy-ness" in LR (or of the CPU) is due to reading/writing to/from the hard drive.
    To test this assumption for LR, I moved some photos from my external (RAID 1) to my internal (RAID 0) hard drive and did some "intensive" work: first some "fancy" lens correction, then a few grad filters, and a "final touch" with the adjustment brush. I thought that LR could handle these tasks somewhat better when the photos were on the internal drive - so some of the "sluggishness" or " freezing" is due to the reading/writing from/to the hard drive.
    Acually I cannot explain why this should be so: In my naivete I thought LR writes everything only into the catalog (?), that - by the way - is on my internal RAID 0 drive.
    I think it would be good if Adobe could look into this and maybe give us some recommendations, just as they do for Photoshop by saying that the scratch disk should be on a different drive than Photoshop.
    But it seems also that local adjustments - spotting, adj. brush. etc - are a very high "number-crunching" business for LR - independent of where the photo is located on the drive. (Interestingly the grad filter is not as bad as the adjustment brush). The clone-tool in Photoshop hardly registers on my CPU and if at all only with a very short spike, while the clone tool in LR sends the CPU through the roof for 10 to 30 seconds- even when the photo in question is on the internal drive.
    I'm sure loots of people will now tell me that this is due to the difference between pixel-based adjustment and non-pixel-based ones. OK, I acknowledge that. But still ...
    It seems some guys are still in denial about this (or maybe they have two quad processors and 16 GB of RAM):
    But it's a fact: LR has a hard time with localized adjustments. There must be by now 100's of complaints to that respect, and that can't be dismissed by blaming it on the hardware specs alone.
    I just hope Adobe is working on that.
    LR3 is a fantastic program that I would not want to work without. Often I have to work on a lot of photos with a very tight deadline. Without LR it would be impossible.
    Thank you,
    ErnstK

    You are right Samoreen.
    I posted my above message in July 2010 and this topic has been re-opened by Adobe under the thread Lightroom 3.3 Performance Feedback
    I think it would be best if everybody would post their concerns only under this thread.
    Otherwise we'd have two different threads for the same issue.
    So let's close this one here.

  • Lightroom 4 performance issues

    Hello,
    Months ago I switched from Aperture 3 to Lightroom 3 and quickly fell in love with the program.
    I switched due to constant freezing and crashes in Aperture 3. I invested time and money to learn Lightroom 3. Performance in Lightroom 3 was superb. Anything I would do with regards to any type of adjustment gave instant results on the screen. Program never crashed or froze onec. Quite frankly, I was shocked in a very positive way.
    This was on Macbook Pro i5, 8GB RAM, Hi Res Antiglare screen with Snow Leopard.
    I purchased Lightroom 4. I did a clean install of OSX Lion and, clean install of LR4. New catalogs, no importing of anything. LR 4 is sooo slow. It works just like Aperture 3 worked, the  precise reason that made me dump it.
    The longer LR4 is opened, the slower it becomes. The more adjustments are applied, the slower it becomes. I will use brush and I have to wait to see results. I can't use brush. It takes me 15-30 min to brush small part of the image. I will slide adjustments and wait. I will click on crop tool and wait, wait, wait. I really love this program but I just can't work like that.
    Would anyone share some light or advice on what could be done, on what is going on?
    Thank you.

    Rob,
    I am working with NEF files and have done so in LR3. I understand from some reading that one of the benefits from converting files to DNG is that they are faster to work with. So I just copied one of my NEF as DNG and I have been working on it for about 15 minutes applying brush after brush and other adjustments to see if LR4 will slow down. Thus far it has been incredibly faster. I will continue to work on this one image and maybe convert few more to DNG to test but do you think that there might be some issue with NEF format? Another bizzare thing I just noticed is that when I open NEF image, my memory quickly goes up to over 3GB and that's not even during applying adjustments. Working now with DNG, memory is just around 1.3 GB. WHAT IS GOING ON HERE???
    I wonder what type of files are other LR4 users that are reporing performance issues working with.
    Please share your thoughts.
    Thank you.

  • Lightroom 4 on Windows 7 32-bit, performance?

    I'm using an HP 32-bit dual-core PC, Windows 7, 4 GB RAM. Yes, I know, I should upgrade to a 64-bit computer but it's just not in the cards right now. Lightroom 3.6 performs reasonably well, well enough for me at least. I tried the Lightroom 4 beta, and it was really quite sluggish. And, it might be my imagination, but it seemed to even affect Lightroom 3. When I removed the beta Lightroom 3 "seemed" to improve in performance.
    I like the new version of Lightroom, but I'm seeing horror stories and am concerned about performance. All of my cameras have full support in Lightroom 3. I get satisfactory results. And none of my reading so far has sold me on switching to the new version. Yes, I know, the new process is far superior. But from my evaluation it is not so superior as to justify sluggish performance. Is anyone using Lightroom 4 on a computer with similar specs as mine? If so, what are your experiences. In the meantime, I will just "suffer" as I continue to use Lightroom 3.6.

    Judy,
    Thanks for clarifying, and I'm inclined to agree with you: Your previous PV2010 workflow is invalid in PV2012, ruined if you will...
    But at least you have acknowledged it, which is step 0. Accepting it is step 1...
    Trying to map PV2010 skills 1-1 into PV2012 is a recipe for frustration.
    PV2012 controls are quite unlike any other editor I've ever used (including Lightroom 3).
    They have image-adaptability, and some intelligence: they don't always do the same thing all the time.
    So yes:
    1. Unlearn everything you know about PV2010.
    2. Learn PV2012.
    In a nutshell:
    For normal photos:
    * exposure sets midtone level, not highlight level (highlights will usually be too bright, initially, when exposure is set correctly).
    * contrast sets midtone separation
    * -highlights to keep highlights from being too bright.
    * +shadows to keep shadows from being too dim.
    * -blacks & +whites for full dynamic range.
    For unusual photos:
    -whites to keep highlights from being too bright.
    +blacks to keep shadows from being too dim.
    For all other photos:
    A combination of the above...
    PS: positive highlights together with negative shadows is typically reserved for:
    * Unusual raw cases, when you want a flatter look (you want to suppress tonal detail / contrast), or
    * Tweaking already baked jpegs.
    Same-signed highlights & shadows values usually means you have exposure set wrong.
    Cheers,
    Rob

  • Lightroom 4.2 Mac OS 10.8 CPU Performance

    I am trying to start a discussion to MAKE Adobe move on fixing this issue of SLOW workflow and horrible hogging of the CPU.  If this doesn't get resolved, my iMac (along with yours) is at rick of being damaged from maxing out CPU ALL THE TIME.  I cant utilize bridge OR photoshop while LR is open. AND YES, I have PLENTY OF RAM, 12GBs!!!!
    I have done EVERYTHING listed in the article provided, "Optimize Performance Lightroom"
    http://helpx.adobe.com/lightroom/kb/optimize-performance-lightroom.html
    This is my busiest time of year and with the new LR 4.2, I have been completely handicapped in my process flow.
    I beg you if you are reading this, PLEASE respond saying your experiencing the same thing. 
    This is your opportunity to let Adobe know they HAVE TO FIX THIS! 
    This is NOT an Apple to Mountain Lion issue, this is all ADOBE!!!!  

    It's not actually Lightroom 4.x or your Mac that is slow — it's all about 2012 Processing Mode that renders ALL of your preferences at real time.
    If you want some boost, switch to Processing Mode 2010 and you'll be surprised how fast it can be.
    I do that for my low importance sets and those are much fster to process then.

  • Lightroom 4.0 beta performance Windows 32 bit

    Yes, I realize I don't have the best system.  I don't need a lecture, I have what I have.  But I hope performance can be improved a little bit.  Lightroom 3.6 performs reasonably well.  But some features in Lightroom 4.0 beta don't do so well.  For instance, I imported about 170 raw images last night, and it took well over 30 minutes for Lightroom to build the 1:1 previews.
    Windows 7
    32 bit

    Our IT guy here at work recommended and sold me this system a couple of years ago.  Said I didn't "need" 64 bit.  I'd like to shoot him now.  Live and learn, I guess.

    Jim,
    LOL. And Bill Gates thought 640K was enough memory for anybody, they say.
    That's about the performance I got on my LR3.6 under Windows XP, maybe a little faster. I was averaging about 12-13 seconds per 12MB raw. Lightroom is like most apps: every release, it is designed to do more and needs faster hardware to maintain the same performance. Everybody wants performance to get better with a new release, but it typically goes the other direction.

  • Very slow performance in Lightroom 3??

    I just upgraded to Lightroom  3.0 and I am very suprised how slow it is!?!  I don't have a very large library and I'm on two reasonably new computers yet the difference from Lightroom 2 (snappy performance) to Lightroom 3 (VERY sluggish) is quite suprising..
    I'm using it on a XP and a Vista system with the same results...
    Is anyone else experiencing this???
    Thanks,
    Ken

    I've noticed a slow down in performance with Lightroom 3 as well. As far a looking around the forum for older threads, ...found older lightroom 1 and 2 threads.
    Your Title "Very Slow Performance in Lightroom 3??" fits what I'm looking for just perfectly.
