412 this, you can set "cgroup_disable=memory" at your boot option to
413 disable memory resource controller and you can avoid overheads.

429 adds more overheads and consumes memory for remembering information.
430 Especially if you use 32bit system or small memory system, please
431 be careful about enabling this. When memory resource controller
432 is disabled by boot option, this will be automatically disabled and
433 there will be no overhead from this. Even when you set this config=y,

694 WARNING: This may break build or kill your cat, as it builds
695 packages with multiple jobs that are probably not tested in
696 a parallel build environment.

698 Only say Y, if you don't mind fixing broken packages.
699 Before reporting build bugs, set this to N and re-run the build.
