As a travel photographer, I find Lightroom to be the best photo editing software, and an indispensable tool. The monthly subscription is a price well worth paying, and I recommend it to all my students on my travel photography course.
Subsequent updates have continued to improve performance, including a major update in mid-2019 and another in late 2020. However, whilst these updates have certainly helped, there are still a few ways to make Lightroom faster.
There are a number of reasons Lightroom Classic might be running slowly. After all, Lightroom is a complex application that performs the dual functions of photography management and photography editing.
To allow you to manage your photo library, Lightroom builds a large database of your images. This allows you to do all sorts of wonderful things from a workflow perspective, like finding images shot with a specific lens, or at a specific shutter speed. Plus there are all the tools like keyword management, labelling and so on. The flip side of this is that a more complicated database take more power to run.
From a photo editing perspective, Lightroom is what is known as a non-destructive editor. Every edit you make can be rolled back, and the original image file remains on disk. Unfortunately, this also means that every edit you make has to be applied and calculated against all the previous edits. So as you make more and more edits to an image, the slower this process becomes.
The good news is that you can improve performance of Lightroom Classic CC by following a number of Lightroom performance tips. Whilst there will always be limitations of what your computer can achieve based on the underlying hardware, these tips should help you get the most out of Lightroom on your computer.
Here are my top tips for improving Lightroom Classic performance, to help you speed up your photography workflow. If you find that your copy of Lightroom is running slowly, trying out these tips should help you speed it up!
If you have a computer with different hard drives inside, and some of those are the older spinning mechanical style hard drives, and some are the newer, faster style SSD hard drives, then you will want to put your catalog file onto the SSD hard drives.
The fast speeds of an SSD means that Lightroom can get image information much faster. In addition, Lightroom stores all its preview files in the same place as the Lightroom Catalog, and the preview file is what Lightroom renders. So you want that to be somewhere that Lightroom can access it as quickly as possible.
If you need to figure out the kind of hard drive in your computer, here are instructions for Windows and Mac. Moving your catalog file is just a question of locating its current location and then moving it in either Windows Explore or Finder. Full instructions on this page.
Lightroom has two places where it caches image data. One is the preview cache as mentioned above, which is stored with your catalog file and used for the library view, and the other is the Camera RAW cache.
Whilst this all sounds good in theory, the reality is that the practice is not quite so simple. First, Lightroom only uses the graphics chip for some specific tasks, so not everything is accelerated. You can see what it can use it for here.
Second, the performance benefits are only usually apparent in specific situations. There is an overhead associated with using the graphics chip, as data has to be offloaded from the CPU to the graphics chip, processed, and then sent back again.
In my experience, larger, higher resolution monitors tend to benefit the most from using the graphics chip, although with the trade-off that there will be a slight delay in the image appearing on screen as the data shuffles between the CPU and the graphics chip. Lower resolution monitors see less benefit, and may even be slower with the graphics chip enabled.
The default setting is Auto, where Lightroom detects the capabilities of your graphics card, and then decides what to accelerate. In theory it should decide between basic acceleration and full acceleration.
Process Version 5 was released in the October 2018 edition of Lightroom Classic. So if you have photos from prior to that time, they will likely still be at an older process version as they do not automatically update.
Note that changing process version can affect how your images look, so you might want to test it out on a few images individually before batch applying it to all your images. This is also why a catalog backup is essential, so you can roll the change back.
Whilst this sounds great in principle, the issue is that writing changes into this file can slow Lightroom down, particularly as the files are usually being written to the hard drive that your photo is on, which will in most cases be a slower, mechanical drive.
This is great, but the synchronisation process is a bit aggressive. In particular, when you are editing a photo, Lightroom will try to synchronise the edits you make to the photo as it goes. This will often include generating a thumbnail of the image and uploading that to the web.
Doing this every time you move a slider in the develop module is clearly suboptimal! Thankfully, you can pause the sync process, just press your name in the top left corner of the screen, and press the play/pause button next to the sync process.
My suggestion is to build standard previews on import. This will slow down the import process, but it will make the Library module far more responsive when you come to review your imported images as Lightroom will be rendering the previews from your SSD rather than building them from the RAW files.
Lightroom also has the option to create 1:1 previews, which are basically the full size version of an image. You can choose to generate these previews on import, but this slows the import process down, and uses up a lot of disk space.
My suggestion is to add an extra step into your workflow. Once you have chosen the images you are going to work with (usually possible with the standard size previews), select them, and then from the menu choose to build 1:1 previews.
Adobe realised that this could be used as a performance workaround, because editing these small files was much quicker than loading up the full RAW file in the Develop module. So in a bit of a hack, Adobe let people choose to edit the smart previews instead of the originals as a performance option.
What this means is that when you are in the Develop module, Lightroom will automatically load the next and previous images in the filmstrip below your photos into memory. In the below image you can see my filmstrip below the actively edited image. The actively edited image is highlighted with a lighter grey background, and the images on either side of it will have been loaded into memory for faster access.
The tip here therefore is to adjust your workflow to be sure that you are editing images sequentially, rather than hopping around all over the place. What I do is use the library to filter the images I am going to work on using the various tools (flags, star ratings etc), and I only load them into the Develop module when I have a series of images that all require editing.
When using the Develop module, the order in which you apply image corrections can have a significant impact on the performance of the Develop module. Every time you make a new edit, it has to apply it and calculate all the previous adjustments you make. This is why the deeper you get into editing an image in Lightroom and the more effects you apply, the slower the Develop module can seem to become.
In an ideal world, all these performance tips would magically solve any performance issues you might have with Adobe Lightroom Classic CC. However, there is only so much you can do with the hardware you have. Lightroom is a complicated tool, and needs a relatively high specification machine to run well.
Keys specs to look out for are a recent processor from Intel in the i5 or i7 lineup, at least 16GB of RAM (although you will benefit from more in my experience, up to 64GB will show benefits), at least one SSD drive, and a dedicated graphics card from either ATI or nVidia.

I really dont like to report this because I think this is a failing of lightroom but the difference in performance between 32Gb and 64Gb is the difference between light and day. I have always struggled with 32Gb and a good CPU to get any sort of good workflow but with 64Gb it is lighting fast
Personally I have a similar age catalog with 400,000 images in, and I think it runs just fine. I have read anecdotal stories about smaller catalogues being faster, but I prefer to have all my images in one searchable location, and it seems to be just fine ?

Lightroom is an image editor and organizer. Its official name is Adobe Photoshop Lightroom, which is somewhat misleading, since it has little in common with Photoshop. While Photoshop, with the exception of the Camera Raw plugin, is essentially a pixel editor that will destructively change the pixels in your files, editing in Lightroom is completetly non- destructive.
All the edits you do in Lightroom are saved to the catalog, which is an SQLite database. It is possible to additionally save the edits to the files (to xmp sidecar files in the case of proprietary raw files), but the edits will not be seen by other applications. Edits saved to files are just metadata that do not change the original files.
To get your images into Lightroom, you have to import them. Lightroom does not open files, and it is not a file browser that you can point to a folder and see the contents. The files you import can be anywhere on your computer, but Lightroom creates a reference to their location in the catalog, and also creates previews of them. All the work you do inside Lightroom is done with these previews, the images you see on screen are not the original files.
