Overcommit
Ratio
Ratio
When memory overcommit is
disabled, this parameter
indicates the percentage of
total available RAM that can
be used for user space
allocations. For instance, if
the system is configured with
an overcommit ratio of 81,
then user space allocations
can use up to 81% of the total
available RAM (leaving 19%
reserved for the kernel).
