For the best results, take a holistic approach. Read all the suggestions here. Consider which ones to implement within the context of your computer setup. Also consider the types of files you use and your particular workflow. Each circumstance is unique and requires a different combination of techniques to achieve the most efficient performance from Lightroom.
The minimum system requirements to run Lightroom are just that: the minimum you need for Lightroom to operate. More RAM and a faster processor, in particular, can yield significant performance benefits. The requirements vary depending on the following:. Find out the system requirements for your version of Lightroom. Using the recommended amount of RAM yields significant performance benefits, especially when you import and export photos, move between photos in Loupe view, or create HDR images and panoramas.
For the simplest workflow, a fast rpm internal Serial-ATA drive is sufficient. For more demanding workflows, consider a RAID array. Storing catalogs, image files, and previews on an external drive is convenient if you work with the same catalog on multiple computers. Doing so, however, can negatively affect Lightroom performance. If you must store your files externally, make sure that you have a fast connection.
For example, use a Thunderbolt connection, USB 3. For best performance, connect the external drive to a compatible port that has the highest bandwidth limit of all the available ports. The bandwidth limits for various ports are listed below:.
Catalog files cannot be stored on network drives but you can store your photos on a network drive. However, network drives hard disk accessed over a network have slower data transfer rates. Therefore, it can take more time when switching modules or when switching from one file to another in Lightroom. Working with too little free hard-disk space can cause poor performance.
See Lightroom system requirements to find out the minimum amount of free hard-disk space you need for your version of Lightroom. Use a compatible graphics processor also called a graphics card, video card, or GPU. Be sure to keep the graphics driver software up to date. If you run Lightroom in bit mode, it has access to more than 2 GB of RAM, which is the ceiling for bit operating systems.
Lightroom operates in bit mode automatically if it is installed on a computer that is 64 bit capable and running a bit OS. You can verify that it's running in bit mode by doing the following:. In the General options, make sure that Open in bit mode is deselected. Drawing to the screen can be slow when Lightroom is using the entire screen of a high-resolution display. A high-resolution display has a native resolution near x , and is found on inch monitors and Retina MacBooks.
To increase performance on such displays, reduce the size of the Lightroom window, or use the or views in the Navigator panel. Temporarily pause Sync With Lightroom while you import and edit your images on your desktop computer. Then resume Sync With Lightroom and let the application sit open overnight for the syncing process to continue and complete.
Lightroom uses previews to display photo thumbnails in the Grid view, the Loupe view, and in the Develop, Slideshow, Print, and Web modules. When you import photos, you can choose from three types of previews of progressively higher quality:. Minimal: These previews are the small, low-resolution JPEG previews embedded in the photos, which the camera generates. They are the fastest type of preview to create.
The Filmstrip and Grid view of the Library module uses minimal previews temporarily, until Lightroom renders standard-size previews for those thumbnails. Standard: Lightroom creates standard previews. They use the Camera Raw engine for processing. So, they sometimes appear different from minimal or embedded previews, especially if you have applied adjustments in the Develop module. You can specify the size of the Standard preview you need, based on the display you use.
Standard previews are used in Filmstrip and Grid view thumbnails, as well as in preview and content areas of the Slideshow, Print, and Web modules. When Lightroom generates previews, it also generates minimal and standard previews, so all three are available to the program as needed.
Because so much data is being processed, previews can take a significant amount of time to create. Any time you zoom to or higher in the Library module, Lightroom uses previews. To display and work with photos, Lightroom requires a standard or preview, depending on the task. This process hinders performance. To increase your productivity and reduce this disruption, manage when and how you render your previews.
Render them on import, or set aside time to render them manually. To render previews on import, use the File Handling panel of the import window. Although generating high-quality, previews on import slows the import process, it makes Lightroom more responsive when you start to work in the Library module.
An alternative, if you want a speedier import process, is to render minimal or standard previews on import. Let Lightroom process the images before you start to work on them. Keeping standard previews small also helps reduce the size of the preview file cache, which speeds performance and saves on hard disk space. To make standard previews small, specify the appropriate the size and quality in the Catalog Settings dialog box:.
For Standard Preview Size, choose the amount that is closest to the longest edge of your screen resolution, but not shorter than it. The larger the monitor you use and the higher resolution , the more work Lightroom does to calculate previews and update pixels when you make adjustments.
Because previews can quickly eat up disk space, Lightroom gives you the option of discarding them regularly—every day, week, or month. As long as disk space is not an issue, keep previews as long as possible to optimize performance. Note, however, that the file that contains the previews, the [ Catalog name ] Previews.
This file is in the same the catalog file. If this option is set to Never, and you experience low hard disk issues, check the size of this file. Delete it if it's too large. By default, Lightroom keeps the preview cache file, [Catalog name] Previews. If you move the catalog file or store it separately from the cache, then Lightroom has to regenerate the previews.
So keep them together. For the default location of the catalog, the preview, and other Lightroom files, see Preference file and other file locations. By default, changes you make to files in Lightroom—adding keywords or fixing red eye, for example—are stored with the photo in the Lightroom catalog.
However, for other applications, such as Adobe Bridge and Camera Raw, to recognize those edits, they are saved as XMP extensible metadata platform data. This data accompanies the image file.
In Lightroom, edits can be saved to XMP automatically or manually. Saving changes automatically, however, can significantly degrade Lightroom performance. Changes are still saved in the catalog, and when you print or export photos from Lightroom, the changes appear in the output. Even if autowrite XMP is turned off, you can manually save metadata changes to individual files at any time. For more information, see Metadata basics and actions.
Lightroom is constantly writing changes to the catalog file. Optimizing the catalog instructs Lightroom to examine the data structure of the catalog and make sure that it is succinct. These processes take a little time but can help keep the catalog operating smoothly. Every time you view or edit raw images in the Develop module, Lightroom generates up-to-date, high-quality previews.
It uses the original image data as its foundation, and then updates the preview for any processing or adjustments that have been applied. The process is a little faster if the original image data is in the Camera Raw cache.
Lightroom checks the cache for the original image data and can skip early stage processing if the image data is cached. If you increase the cache size, it can store more image data, which in turn speeds the generation of previews of those images.
Some Lightroom users find that increasing the Camera Raw cache to 20 GB or more can dramatically speed performance in the Develop module. To increase the Camera Raw cache size, do the following:.
To further speed the cache, keep it on a fast hard disk. To specify the location of the Camera Raw cache, do the following:. In the Camera Raw Cache Settings area, click Choose and navigate to the location where you want to store the cache.
If your image contains many hundreds of localized adjustments, consider using a pixel-based editing application such as Photoshop for that level of correction. If you have many corrections, check your History panel. The History panel has no limits, and it isn't deleted unless specified. If you've been creating many local or spot corrections, your history could be long, which can slow Lightroom's performance as a whole. Note : Performing spot healing first improves the accuracy of the spot healing, and ensures the boundaries of the healed areas match the spot location.
This suggestion applies especially to local corrections. Each slider you've changed when applying local corrections or the gradient filter is applied to that entire correction. And, each option uses resources and can affect performance.
When applying local corrections and gradients, make sure that you need all the corrections you've selected.
