Allocating Memory & Image Cache
The Memory & Image Cache preferences give you control over how much RAM memory is assigned to Photoshop, and how much memory is allocated to screen draws (Image Cache). Photoshop, being a high-performance application, requires a fairly large amount of RAM memory. Adjusting these options can help increase Photoshop’s overall speed performance. Photoshop uses many things that effect RAM memory: History States, Undo, Clipboard, and Cache. When you modify the cache settings, you are increasing or decreasing the amount of RAM Photoshop uses for various tasks. Experimentation is the key here. Try different settings and record Photoshop’s performance. By fine-tuning Photoshop’s engine, you increase it’s overall speed, and you’ll get more design miles to the gallon.
