When you select the Efficiency option, Photoshop lists the amount of time it spends running operations in RAM compared with swapping data back and forth between the hard disk. A value of 100 percent is the best-case scenario. It means Photoshop never has to rely on scratch files. Low values indicate higher reliance on the hard disk and, as a result, slower operations. Adobe recommends that if the value falls below 75 percent, you should either assign more memory to Photoshop or purchase more RAM for your computer.

The Efficiency option is a reality check. If it seems Photoshop is dragging its feet, and you hear it writing a little too often, you can refer to the Efficiency rating to see if performance is as bad as you suspect. Keep in mind, hearing Photoshop occasionally write to disk is not, in and of itself, cause for concern. All versions of Photoshop since 3.0 automatically copy open images to a disk buffer in case virtual memory is later warranted. In fact, this is the reason Adobe added the Efficiency option to Version 3.0.1 — to quash fears that a few sparks from your hard drive indicated anything less than peak performance.
