this, you can set "cgroup_disable=memory" at your boot option to

disable memory resource controller and you can avoid overheads.

usage of swap...a process can exhaust all of the swap. This extension

adds more overheads and consumes memory for remembering information.

Especially if you use 32bit system or small memory system, please

be careful about enabling this. When memory resource controller

POSIX variant of message queues is a part of IPC. In POSIX message
|
|
queues every message has a priority which decides about succession
|
|
of receiving it by a process. If you want to compile and run
|
|
programs written e.g. for Solaris with use of its POSIX message
|
|
queues (functions mq_*) say Y here.

POSIX message queues are visible as a filesystem called 'mqueue'
|
|
and can be mounted somewhere if you want to do filesystem
|
|
operations on message queues.
