    Export Why Is Export Now So Slow?

    Since the latest upgrade, exporting even a single file is super slow compared to how fast it was before upgrading to 9.3. It now takes 35–40 seconds (I timed it) for the operation to complete. I have a new, fast Mac, so it's not a hardware issue. The strange thing is, the "Export n files"...

    Smooth Upgrade to 9.3 - Performance Now in the Crapper

    I frankly don't understand what Adobe is up to. If they can't do proper regression testing, then they are being abusive to their customers, forcing production users into their beta testing program. This upgrade smooth, and painless. However, with this latest update, the performance is something...

SO basically what happens is when i;m sorting files, lightroom hangs and the disappears entirely for a second before reappearing and kicking back into action. A process called Shadow...

    Does Lr Place More Demands on Processor or Memory?

    My iMac is six-plus years old and for various reasons I decided to upgrade to a new one. I bought one with a 3.0GHz 6-core 8th-generation Intel Core i5 processor and upgraded the memory to 32GB. (I also chose to get SSD storage instead of a hard drive or a Fusion drive.) I've already ordered...

    Develop module Graphics Card for LR8.4 - is it worth it?

    Hi, I've seen several threads about LR8.4 now doing more in GPU and which graphics cards support "full" or only "basic" acceleration, etc... What I'm missing is a statement, if it's worth it? (I mean the "full" acceleration) Sure one might say this depends on the usecase, but does it really...

    Slow to change images with huge local storage on Windows

    I'm s huge fan of fast local and offline access to all my photos in Lr CC so always try to store all the albums locally. On the iPad Pro I manually store every album locally, and with the 1 TB storage I've been able to store all 380K photos. The albums switch at once and photos come up faster...

    Performance Lightroom 6.14 vs. Classic CC 8.x on 2 cores?

    Hi guys and girls, I've been pondering upgrading LR 6.14 to the subscription model (Classic CC 8.1 currently) for a while now. I only have a Macbook Air with 2C/4T and I'm wondering about the performance uplift. I've only seen benchmarks on higher end platforms on Pugetsystems.com, which don't...

    GPU Acceleration

    Now that recommended or actually useful graphics cards are becoming affordable, I just picked up a Asus GTX 1060 6GB card for my five year old PC. It seems faster although I am not sure if I am imagining things or not. PC RAM usage, of which I only have 16GB, also seems lower. Has anyone...

    Operating System: Windows 10 Exact Lightroom Version (Help menu > System Info):Lightroom Classic version: 7.1 [ 1148620 ] I have been experiencing really bad performance issues lately -- not exactly sure when it started but think it may have been after the CC and Classic install.

    LR Performance & SSDs

    One can always learn something new...I am new around here, can't tell if you have already discussed it, but today I stumbled upon this video about "SSD Overprovisioning", which could be LR related.

    Lightroom on Microsoft Surface Pro (2017)

    Have any of you started using Lightroom on the new Surface Pro? I'm curious how usable one would be as an editing machine, and particularly how much difference in performance there is with LIghtroom between the i5 versions and the ridiculously expensive i7 versions. Thanks.

    Unbelievably slow performance

    I hope the problems I'm having are with Lightroom and not my recently purchased iMac. I updated my old system and now have a 3.3 GHz i5 with 24GB 1600MHz 2048 DDR3 and a 2TB Fusion drive, running El Capitan, (so apparently no slouch). I am using Lightroom CC 2015.10 but at times I feel like I...

    Performance issue

    Have windows 10 with 16gb ram. When in developing module and using spot removal or adjustment brush as I'm working the image area goes black and then back again?? Also when using spot removal, heal or clone, there is some blur remains after using clone or heal - how to over come this?

    Using lightroom to manage 4k videos

    I use lightroom 5 as a library tool to keep track of my photo and video clip collections and perform basic editings (mostly cutting). Most clips are no more than 30 seconds long. I run lightroom on laptop so that I manage my media at home or on the road. So far I am happy with this workflow...

    Lightroom crashing (Windows version)

    I am running Lightroom CC under Windows 7, 64 bit. My computer is several years old, but should still be good enough to run Lightroom without a problem, even though my catalogue is quite large (about 26 GB). It has, however, been plagued for some considerable time by Lightroom crashing...

    Graphics card for a 4k monitor

    I know some of this has been covered before but I need some further advice. I recently upgraded my monitor to a lovely, wonderful etc, etc Dell UP3216Q, which runs natively at 3840x2160 (i.e. 4k). It cleared out the bank but the images are great, so much so that a professional photographer...

    Need help choosing the right mac for lightroom

    Hi there I'm new to this forum. Initially I was posting this question in a mac forum... but the lightroom part seemed to be too specific for most users there. I really hope that someone here can give me a recommendation. My wife is a photographer and is using an older macbook pro at the...

    Takes too long to zoom in 100%

    LR5.2 CPU: i5-3380M @ 2.9GHz 8GB Ram Win7 Prebuild 1:1 Preview Takes 5-10 second to zoom in 100% on 5d3 or 6d Raw files, that have not been edited. I think that's too long. How to bring it down under a second without hardware changes? I can not imagine modern computers require 10 seconds to...

    Performance 2015.6

    I wonder if Victoria can address this - Victoria noted two performance improvements in 2015.6 (Batch Export and Develop Advance to next image). These truly do seem better. However, I cannot find any mention of these in the Official Blog from the LR team, Lightroom Journal. So, I am wondering...

    Response time when working on catalog/images on an external drive

    Is there a way to cache 1:1 image previews and camera raw on a per catalog basis? For example, I have a catalog of over 10,000 images on an external drive. I want to keep the cache on that drive to improve performance. Is this possible? If not, are there any tricks to improve response time...
