Tips and Troubleshooting
Windows Seems Slow
If Windows performance seems slow, try the following:
• Quit applications and programs you aren't using: If you run a number of memory-
consuming applications and programs simultaneously, Windows performance may become
slow. Quit any applications that you aren't using. You can also use Activity Monitor (located in
the Mac OS X Finder in Applications > Utilities) to see how much of your Mac's memory each
application is using. That way, you'll have a better idea of which applications cause
performance to degrade the most.
• Change how much memory is allocated to Windows: Parallels Desktop is set to allocate a
certain amount of your Mac's available RAM memory to Windows and the rest to Mac OS X. If
too much memory is allocated to Windows, Mac OS X may slow down, which in turn can cause
Windows programs to slow down because they're running on top of Mac OS X. If, on the other
hand, too much memory is allocated to Mac OS X, then Mac OS X applications may run well
but Windows programs might slow down.
To optimize the performance of both Windows and Mac OS X, set the memory allocated to
Windows (p. 104) to be somewhere within the recommended range, indicated by the graphic
under the memory slider in the General configuration panel (see below).
