文档介绍：Chapter 2: Exploring the Photoshop Workspace
Adjusting Performance preferences
The Performance preferences pane in Photoshop provides options that allow you to configure
settings that can help it perform better. Photoshop is a very memory- and disk-intensive appli-
cation and as such, the better you adjust the performance, the faster it can plex
operations such as Puppet Warp and Liquify. There are several settings that you can adjust in
Photoshop, such as scratch disks, memory usage, and graphics processing, to improve its per-
formance. The Performance preferences pane, shown in Figure , provides the following set-
tings to improve some of the Photoshop features that are performance-intensive:

The Performance settings in the Preferences dialog box allow you to limit Photoshop so it
does not consume resources on your system. 2
Memory Usage. This section defines how much system memory Photoshop is allowed
to consume. It displays the current system memory and gives a suggested range. The
slider and text box define the maximum amount of RAM Photoshop is allowed to use.
Processing images is very CPU- and RAM-intensive. The more RAM you allow
Photoshop to consume, the faster it performs; however, less memory is available for
other applications.
CAUTION
Allowing Photoshop to consume too much memory can lead to extremely poor system performance that affects all appli-
cations, even Photoshop. This is one case where more is not necessarily better.
Scratch Disks. This section displays a list of devices that you can select for scratch
disks. Photoshop uses scratch disks to cache data not currently being used when it is
processing data that requires more memory than the system has available.

TIP
You get the best performance when working with Photoshop if you use three separate disk drives to store the Photoshop
application, scratch data, and i
