Release of Lightroom CC 2015.6 VERY SLOW!

Hi guys,.

I use Lightroom CC 2015.6 contacted Camera RAW 9.6 out of 10 Pro 64 bit and I have pretty decent rig: i7 6950 X (10 carrots), Asus Radeon Strix 1080 GTX, 64 GB 3200 RAM, SSD on PCI.  'Use the graphics processor' is enabled in my preferences of LR, but I don't see an important when different it is turned off.

First of all it takes LR about 3-4 seconds per image to build 1:1 previews, which means several hours if I have thousands of images from a shoot.

When I try to get a glimpse of some of the images at 100%, and to quickly move between them it works fine for maybe 5 minutes and then it starts to slow down: it takes LR seconds to create each preview and also from seconds to move between images. Furthermore, the previews are 3840px in size and average quality.

In Manager tasks I can see that at the start after start LR uses only 5-10% of my CPU resources and about 2 to 5 GB of RAM, but after a few minutes the use of RAM increases 15-20 GB and that's when LR becomes very slow. It seems he keeps each image previewed in memory and not release to the system when I close the preview.

I also tried another software to compare and other programs were significantly faster (Aftershot Pro is the fastest, followed by DXO Optics Pro and Capture One).

So it seems that this problem is strictly linked to the software and not to my material at all. Also, I noticed that after the recent updates, so I wonder if relling until one of the earlier versions might help.

Ideas to improve my experience with the latest edition of LR?

I'm really scared, because I don't really have time to wait for the software when working on thousands of images each week.

Your response will be appreciated. Thank you!


This is the official Adobe performance help page.
Adobe Lightroom GPU troubleshooting and FAQ

You have your system configured to save all 1:1 previews in your catalog for ever? I set mine to delete every 30 days, so I don't have all that stored somewhere in a cache with LR.

Because it goes so slow down anyway I don't think you have much to lose by trying to clear your cache. But read up on it before making this decision.

In addition, if your photos are stored on an external I wonder if there is a problem with this external hard drive bus speed?

Or if it's all beings stored on your local disk with the OS and applications, maybe it's having a shape any conflict with something the OS or a partner app? Do you think these performance issues when other applications are turned off? Just think-tanking with you here because it seems to have no else responded yet.
Hope of those is the solution.

  • Lightroom 6/CC export very slow

    Not just slow. Ridiculously, unusable, costs me slow money.

    The Setup is an i7 3.1 Ghz overclocked (running up to 3.3 GHz), 16 GB RAM, SSD (Samsung 850 Pro mSATA) with OS and app catalog, second SSD (SATA 850 Evo) with photos on, hide on RAM disk. Windows 10 and LR 6.11.

    Export is painful, but the current example is 131 Nikon D4S and D810 RAW files at 648-pixel wide < 200 k files (not my choice...). It is by replacing older versions and it took 20 minutes to bring up the dialog box "Do you want to overwrite?" and was more than an hour "export readiness. Based on the previous batch, I believe nothing will happen for about 40 minutes after the export dialog preparation goes missing, then it will start to export and take about an hour to do the export. Before the last update, I think that the entire sequence would have been 5-10 minutes... I optimized the catalog, but that did not help.

    I also have problems to export in Lightroom 2016/CC. That's slow by glaciers

    Help > system information to check which version of LR that you are running.   If you are on LR CC 2015.2, it contains a serious bug with export: Lightroom version 2015.2 crashes Upon export/external edition.

    You can update to CC 2015.2.1, just released, and that may well solve the problem.  But there are many other issues widely reported to 2015.2 that 2015.2.1 does not correct.  So, me and others, recommend that return you to CC 2015.1.1, following the instructions here: how I roll back to Lightroom 2015.1.1 or Lightroom 6.1.1? . Wait until Adobe cleans up the mess and release 2015.3.

  • Lightroom CC 2015.2.1 slow and freezing up

    Hi all!

    I use Lightroom CC per day to sort and edit hundreds of images by casting. It's my lifeblood for the work!

    The program has worked flawlessly until the update to 2015.2.1. After the update, I started to meet the constant lag while spending scrutinized in the Gallery of the library in my catalogs, as well as trying the module development allows you to change the basic elements of photography...

    I can hardly move around the program without having to wait 5 minutes for any movement appears on the interface. The filter metadata on the right, sometimes crashes and I have to force quit the application and restart my computer to get the program works again... for 5 minutes.

    After reading the help forums I have unchecked the use GPU, optimized my catalog, all saved as usual, still lower previews to the option of smaller size. No chance for the program become stable for me to use it with ease.

    Thank you for reading and please let me know if anyone has any advice as to why the interface freezes and performance stops whenever I run the program. I have included below the information about my software and hardware in case this is useful.

  • Lightroom 2015.6 Painfully slow since update

    I use Windows 10, 16G memory, processor GPU active.  Since the upgrade to 2015.6 a few days ago, the development is very slow.  Very slow movement of the photo for the photo and the delay in introducing changes.  Everyone knows about these problems?  Thanks in advance for any help you can offer.


    Memory leak was identified in LR 6.6 and 2015.6 CC: Lightroom 2015.6 extremely slow. Community customer Photoshop family

    My system with 12 GB memory begins to slow from LR reaches about 50% memory usage and then worsens when you browse or edit images in the develop module. It will cause lag adjustment brush which worsens when you change pictures more. This is regardless of the setting of GPU in LR preferences. Some have found reducing the window of LR, wait 2-3 seconds, and then maximize it frees additional memory. In my tests, it helped some, but closing and recovery then LR releases even more memory. In addition, if you rarely shutdown and restart your system, this can reduce the amount of available memory and other issues. I suggest to close your system at least once a week. The maximum amount of memory will become available for use by LR during the next reboot.

    That's all you can do for now until an update with a fix is released.

  • Lightroom works very slow all of a sudden

    I searched and read all the forums on the optimization of the performance of Lightroom (How to improve and accelerate the performance of Photoshop Lightroom) and have watched many videos with tips on improving the performance on YouTube and have not yet found a solution.

    Question: After a few months of using Lightroom, it suddenly became unusably slow. It was not a demonstration of deliberate for its slow over time. Instead, one day it was usable, and the next day he was not. Even in the library module it lags to switch between images. When I press F for full screen, where it was instantaneous and now takes about 10 seconds and is then stuck in fullscreen. This is true for the large images and old photos of iPhone even in low resolution. Can import is no longer the same wait more than a minute between clicks.

    On my computer

    • 2015 Macbook Pro (a few months)
    • OS X El Capitan 10.11.2 running
    • Intel Core i5 at 2.7 GHz
    • Memory - 8 GB 1867 MHz DDR3
    • Graphics - Intel Graphics Iris 6100 1536 MB
    • Hard total is 120 GB
    • Drive hard use 96 GB of the - 47 in photos and approximately 22 GB in "others" which I suppose is a majority of the Lightroom data
    • I almost exclusively use this machine for browsing the web and photography. Nothing else. very few other programs and file type

    On my Lightroom

    • Lightroom CC
    • 2015.2.1 release
    • 5 864 total photos on the computer and my main Lightroom Catalog
    • Only about 60 have changed considerably in the develop module
    • Majority taken on a JPEG of A6000 Sony 24MP camera

    What I tried to solve the problems, does not

    1. Read a lot on the size of the catalog. Mine is still quite small, but I've tried closing the catalog and begin a new one with about 200 shots straight out of the camera. This has not solved the problem.
    2. Optimized catalog
    3. Preferences changed to automatically reject 1:1 previews after a day.
    4. Top left says nothing about the rendering preview. This along with the fact that the issue has been sudden leads me to believe that "Preview size" are not the issue, but I could be wrong.
    5. I tried to move all my photos on an external hard drive fast - catalog file was still on my computer, but I had a lot more space on the machine. This has not solved the problem
    6. I turned off of face detection, because he had tried to distinguish faces
    7. Increased raw cache size of camera

    Lightroom isi the only app I had problems with. Everything else is zippy and smooth. Help, please!

  • Backups Time Machine very slow on 2015 MacBook Air

    Associated with a topic of discussion between a few days ago (two MacBooks, 10.11.4, a fast Time Machine backup and a very slow), I start a new topic with new information that seem to show it is a problem more general and not related to Time Machine networks.

    Here's the situation:

    • A 2015 MacBook Air, 10.11.4, 8 GB / 512 GB, has extremely slow performance of backup Time Machine, taking 40 hours for the first 300 GB backup and incremental backups for a long time as well
    • TM performance is essentially the same whether on the network (wired Ethernet) or a USB3 external disk
    • When you back up to disk USB3, I confirmed that the information system shows that the port is configured as USB3, not USB2 (nothing else is plugged into the USB port)
    • Tests of bandwidth I/O gross (using dd and iperf) show no problem; the network reached 110 MB/s bandwidth, written network managed at 50 Mbps, external USB3 HD written work at 40-50 MB/s (write hard drive speed limit)
    • 3 other Macs of various ages from 2009-2014 on the same network have no problem at all do backups Time Machine Network; a backup complete first on a 2011 MacBook Pro 500 GB takes 5 hours or more than 10 x faster than the MBA problem
    • Time machine network uses a Linux server running the latest Debian and Netatalk 3.1.8 and the connection is via a USB3/Gigabit adapter, no WiFi, and iperf tests with this arrangement shows 900 MB/s of throughput of the server.  In all cases, the Time Machine and external time Machine Network USB HD have the same symptoms.
    • The problem with MacBook Air is configured the same as the MacBook Pro 2011, which she replaced "daily driver", possible
    • This problem was shown by the MBA since his unboxing conversion, taking 20 hours for his first backup once Setup initially.  Incremental backups now take several hours, leading to interrupted incremental backups and, I believe, databases corrupted backup triggers new full backups that take today the 40 hours.

    Using Terminal Server and iostat, Console, etc, I see that there is significant activity e/s for the backup drive on the order of 20 to 40 MB/s for long periods on the MBA during the TM backup, but during that time the average declared backup size as shown in the window in the console and TM is growing by only 5 GB/hour.  This occur even if the backup will the external drive or a network drive. This seems to mean that the I/O bandwidth to and from the disk hard external, only 1/600 contributes to the progress of the backup.  I am sure that there is overload of certain checks and other tasks, but not to a 600-to-1 ratio.

    I tried to disable the limitation of the I/O of low priority as shown here: close-el-capitan-upgrade, that helps a bit (maybe 20-30%), but not by a factor of 10 for others.

    I have gone through a number of the Time Machine of Pondini troubleshooting steps, but he found nothing corresponding to these symptoms.

    The only thing I can conclude is that Time Machine, the application or configuration, on this specific MBA, is down. (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

    Does anyone have advice on what to watch next?  In all cases, only one key would be why it seems that only 0.16% of all the bandwidth I/O to the backup drive seems to be actual data backup.

    Once again, three other Macs, all running the same 10.11.4, back to the Time Machine Server perfectly and have for years.  Only this new MBA glue as broken out, either to a network drive or an external hard drive USB3.

    (A single thought that I wrote this to the top that I have not tried: the MBA and the time MBP running VMware Fusion and have a file of 50 + GB VM; on the MBA that is not excluded from TM backups while on the MBP is)

    What happens when you exclude it as the MBP?

  • Develop module is slow to load images in Lightroom CC 2015

    Whenever I look at a new image, it is slow to load in the develop module. Which means that when I click on a thumbnail, the image looks flat and not edited for 1-2 seconds until finally, it support. This occurs even after the generation of previews of standard sizes.

    The library module is always fast and has no problem with that.  This problem did not exist before the update of Lightroom CC 2015.

    Everyone has noticed this or a solution?
