CommittedAS
CommittedAS, short for Committed Address Space, is a memory-management concept used by operating systems to describe the portion of virtual address space that has been allocated for use and is guaranteed to be backed by physical memory or swap (or other backing store). It represents the kernel’s commitment to provide backing storage for memory allocations, even if the pages are not currently resident in RAM.
The concept sits between total virtual address space and actual physical memory usage. An application may allocate
Measurement and reporting: CommittedAS is reported by the operating system as part of memory accounting. On
Relation to other metrics: Virtual memory size (VMS) reflects the total address space allocated to a process,
