If your hard disk is fragmented, playback of audio will be slower.
Use the Disk Defragmenter to correct the situation.
Dithering subtly improves your mix, but most people can't hear
it. Turn it back on for mastering.
By default, SONAR bypasses all disk caching, which typically
results in better performance with audio data. If your computer
has an older IDE disk controller, or a disk controller that does
not use DMA transfers, enabling caching may improve
SONAR's audio performance. Note: Changes to these settings
only take effect when you restart SONAR. Choose Options-
Audio and click the Advanced tab to change the Enable Read
Caching and Enable Write Caching settings.
Drawing the contents of audio clips in the Clips pane uses some
CPU cycles. If you are using a slow machine, you may want to
disable this feature. To do so, right-click in the Clips pane,
choose View Options, and disable the Display Clip Contents
option.
