O valor Committed_AS de / proc / meminfo é afetado pelo aumento / diminuição no Buff / Cache? O Proc Manual define o commited_as como abaixo, estou assumindo, o buff / cache não vai afetá-lo por favor me avise se eu estiver errado.
Committed_AS: The amount of memory presently allocated on the system. The committed memory is a sum of all of the memory which has been allocated by processes, even if it has not been "used" by them as of yet. A process which malloc()'s 1G of memory, but only touches 300M of it will show up as using 1G. This 1G is memory which has been "committed" to by the VM and can be used at any time by the allocating application. With strict overcommit enabled on the system (mode 2 in 'vm.overcommit_memory'),allocations which would exceed the CommitLimit (detailed above) will not be permitted. This is useful if one needs to guarantee that processes will not fail due to lack of memory once that memory has been successfully allocated.
