What are private bytes and working set?
Private Bytes are the actual bytes allocated by your app, including pagefile usage. in general, private bytes are the overall committed memory. while the working set refers to the memory that is backed by RAM.
What is private memory in Windows?
Private memory, is defined as memory allocated for a process which cannot be shared by other processes. This memory is more expensive than shared memory when multiple such processes execute on a machine.
What is commit working set shareable private memory?
Private is the amount of unique memory that is used by a process; Shareable is the amount of memory in use by a process that is also shared with other processes, including possibly system processes; Working Set is the total of Shareable + Private; and Commit is how much virtual memory has been reserved for a process.
What is working set in memory management?
The “working set” is short hand for “parts of memory that the current algorithm is using” and is determined by which parts of memory the CPU just happens to access. It is totally automatic to you. If you are processing an array and storing the results in a table, the array and the table are your working set.
What is the difference between private bytes and virtual bytes?
The Private Bytes counter indicates the total amount of memory that a process has allocated, not including memory shared with other processes. The Virtual Bytes counter indicates the current size of the virtual address space that the process is using.
What is the difference between commit and working set memory?
So you can think of the working set as the amount of physical memory used, while the commit size indicates the amount of virtual memory used (sans things like DLLs or memory mapped files, which can be back by files other than the page file).
What is the purpose of the working set model?
The working set is intended to model the behavior of programs in the general purpose computer system, or computer utility. For this reason we assume that the operating system must determine on its own the behavior of programs it runs; it cannot count on outside help.
What is private working set in Windows 7?
So basically private working set is the subset of working set that specifically describes the amount of memory a process is using that cannot be shared by other processes. If you notice the task manager in Vista & Windows 7, window shows Memory (Private Working Set) which is the key thing to consider in case of memory issues.
What is private working set memory in Windows XP?
If you observe Windows XP’s task manager, it shows “Mem Usage” which is basically ‘Memory (Working Set)’ and this is sort of general memory for that specific process. Windows XP do not support\\show private working set memory.
What is the difference between private bytes and working set?
Private bytes are also not exclusively physical memory; they can be paged to disk or in the standby page list (i.e. no longer in use, but not paged yet either). Working Set refers to the total physical memory (RAM) used by the process.
What is private memory in C++?
Private memory, is defined as memory allocated for a process which cannot be shared by other processes. This memory is more expensive than shared memory when multiple such processes execute on a machine. Private memory in (traditional) unmanaged dlls usually constitutes of C++ statics and is of the order of 5% of the total working set of the dll.
