Increase Lightroom Camera Raw Cache
April 16, 2011
Every time we view a photo in Lightroom the image must first be loaded into Camera Raw. That’s where Camera Raw cache comes into play. It caches recently opened images so that it’s faster the next time we opened them. Caching this data significantly shortens the loading time when we return to a previously viewed photo.
By the default the Camera Raw Cache is set to 1.0 GB. It is highly recommended to increase the size of the cache to at least 40gb. I have mine set at 50gb and if you have plenty of drive space increasing it can greatly improve performance.
To change or increase the size of your Camera Raw Cache, just click on Edit –> Preference and your all set.
