VSIZE (Virtual memory SIZE) – The amount of memory the process is currently using. This includes the amount in RAM and the amount in swap. RSS (Resident Set Size) – The portion of a process that exists in physical memory (RAM). The rest of the program exists in swap.
What is RSS and VSZ memory?
RSS is the Resident Set Size and is used to show how much memory is allocated to that process and is in RAM. … VSZ is the Virtual Memory Size. It includes all memory that the process can access, including memory that is swapped out, memory that is allocated, but not used, and memory that is from shared libraries.
What is VSZ in ps aux?
VSZ is short for Virtual Memory Size. It’s the total amount of memory a process may hypothetically access. It accounts for the size of the binary itself, any linked libraries, and any stack or heap allocations. When a process is started, VSZ memory becomes RSS memory, over which we’ll go now.
What is RSS in Linux process?
In computing, resident set size (RSS) is the portion of memory occupied by a process that is held in main memory (RAM). The rest of the occupied memory exists in the swap space or file system, either because some parts of the occupied memory were paged out, or because some parts of the executable were never loaded.
What is VSS and RSS in top command?
VSS (reported as VSZ from ps) is the total accessible address space of a process. This size also includes memory that may not be resident in RAM like mallocs that have been allocated but not written to. … RSS is the total memory actually held in RAM for a process.
What is RSS memory?
The RSS (Resident Set Size) is the amount of memory usage that is present in RAM. But modern operating systems rely heavily on shared memory. If two processes use the same system library, then the system library’s memory usage is shared between those processes.

What is PS in terminal?
The ps (i.e., process status) command is used to provide information about the currently running processes, including their process identification numbers (PIDs). A process, also referred to as a task, is an executing (i.e., running) instance of a program.

What is RES memory in Linux?
RES is the total physical memory used shared or private that the process has access to. SHR is the total physical shared memory that the process has access to. DATA is the total private memory mapped to process physical or not.
What is maximum resident set size?
Collectively, the total amount is the virtual set size. The peak resident set size (Peak RSS or Max RSS) refers to the peak amount of memory a process has had up to that point.

What is Procrank?
procrank. procrank will show you a quick summary of process memory utilization. By default, it shows Vss, Rss, Pss and Uss, and sorts by Vss. However, you can control the sorting order. procrank source is included in system/extras/procrank, and the binary is located in /system/xbin on an android device.

What is VMsize?
VMsize is the “address space” that the process has in use: the number of available adresses. These addresses do not have to have any physical memory attached to them. ( Attached physical memory is the RSS figure)
