CPU Meters
The CPU Total meter displays session performance
for Elastic Audio processing, Clip Gain process-
ing, and Native plug-in and mixer processing. A
3-second peak indicator provides visual indication
of peak CPU usage.
The individual
CPU meters provide a general indi-
cation of how much Pro Tools is using each of the
processors in your computer.
Activity Meters
The Activity section of the System Usage window
display meters for disk usage and memory usage.
Disk Meter
As in previous versions of Pro Tools, the Disk me-
ter displays the amount of hard disk processing ac-
tivity.
Disk Cache Meter
The System Usage window lets you monitor use of
the Disk Cache. This meter is only present if a
fixed
Cache Size is selected in the Playback En-
gine dialog.
The Disk Cache meter
indicates the amount of al-
located
memory being used to cache audio in the
timeline (up to the amount of RAM selected for the
Disk Cache setting in the Playback Engine). An
additional peak-meter style indicator
is included to
show how
much of the allocated RAM is needed
for caching
the session.
Memory Meter
The Memory meter displays how much of the in-
stalled physical RAM in the system is being used
by Pro Tools. This includes RAM used by the au-
dio engine, the video engine (if enabled), plug-ins,
and the disk cache. Other than Pro Tools, it does
not show any other RAM usage by the system. If
the Memory meter approached 100%, install more
physical RAM or lower the Disk Cache setting in
the Playback Engine dialog.
