PURGE
Syntax
PURGE [ASYNC]
Description
Release unused memory back to the operating system.
Options
ASYNC- Performs the operation in the background.
This command is generally not needed for normal operation because the system
allocator typically releases unused memory over time.
But in some cases this can speed up the process, such as with the
FLUSH/SWEEP/PURGE combo which will clear all entries and free up all memory as
soon as possible.
