Lightroom is an awesome software for photographers, there are however a few things you can do to sppe it up.
1. Render Minimal Previews
To seped up the initial import process, During the Import process, under ‘File Handling’, be sure to set ‘Render Previews’ to ‘Minimal’.
2. Use a large Cache Folder
Under the ‘Edit’ menu, go to ‘Preferences’, then ‘File Handling’, and change the size of your Camera Raw Cache settings to the following:
JPEG Preview: Medium Size
Maximum Size: 25gb
(Leave any other setting in its default state)
*Tip* Set your Camera Raw Cache to a size that is equivalent to your average photo job, making it slightly larger if possible.
3. Change your Standard Preview Size
Go to Catalogue Settings in the Edit menu. These are specific per catalogue so you may have to update them in each.
Depending on the size of your monitor, you should change the size of your previews. For example, if you’re on a 17″ monitor running 1280 x 1080 or similar, you can probably afford to use 1440 pixels or slightly less as your Standard Preview Size. 1024 may be sufficient.
On a 24″ monitor (1920 x 1200), you can choose 2048 as the Preview Size.
4. Optimise the Lightroom Catalog
Go to ‘File’ and select ‘Optimise Catalog’. It might take a few minutes depending on the number of images, but this should speed your catalog up noticeably.
5. Render 1:1 Previews
To prevent too much loading while in the edit module, you should render 1:1 Previews prior to working. This can be done in the main Lightroom screen (as opposed to the Import screen).
First, select all your images by clicking on ‘All photographs’ in the Catalog Panel. Then click ‘Library’ in the menu, then ‘Previews’ and select ‘Render 1:1 Previews’. Then select ‘Build All’.
This process takes a lot of time, but is well worth doing .
