It also tries to describe private memory size as a percentage of working set size, which is nonsensical. Can you shed some light? The former is a virtual size and will be the same for every use of the code with the same input while the latter is physical which can be radically different from one run to the next, depending on how much memory-rich or -starved the machine is. Profilers are everywhere these days; use one. You should not try to use perfmon, task manager or any tool like that to determine memory leaks. The paged part of the process represents a very important piece of information: memory committed and not used frequently or rarely used. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Sorry to disappoint. Virtual Bytes is the current size, in bytes, of the virtual address space the process is using. In this post I would like to discuss how it can be lacking as a memory tracker, and go over alternatives that could replace it.

Private Bytes refer to the amount of memory that the process executable. The definition of the perfmon counters has been broken since the.
private bytes explained Private bytes is the process's committed private virtual address space. Some of this may be in the pagefile, some in RAM, some in both.
Private bytes explained
As far as I remember, the difference between the working and the private set is the amount of memory an application can share with other.

Once it gets accessed again, it gets brought back into memory. StephenKellett, Is there a trial version?

High contrast. It also tries to describe private memory size as a percentage of working set size, which is nonsensical.

|I am trying to use the perfmon windows utility to debug memory leaks in a process. This should show you where the volume is stuck. I can't even run a simple class file in Java?
This cannot, however, prove that there is or is not a leak. Private bytes is a reliable indicator of a leak the application memory space. If you have used a computer for more than five minutes, then you have heard the words bits and bytes.
There are different types of ways memory can be allocated.

Notice in the image below. Committed memory is the amount of virtual memory reserved for a The following programs consumed the most virtual memory: () consumed bytes, OUTLOOK.
Memory that is backed is referred to as Committed. Private Bytes are a reasonable approximation of the amount of memory your executable is using and can be used to help narrow down a list of potential candidates for a memory leak; if you see the number growing and growing constantly and endlessly, you would want to check that process for a leak.
OS Paging is an amazing idea. Use Process Explorer instead.

The definition of the perfmon counters has been broken since the beginning and for some reason appears to be too hard to correct. January 05,

|Note: I'm avoiding the word "reserved" because of possible confusion with virtual memory in the reserved state which is not committed.
Until I started working with machines that has s of GBs of memory and apps to match.

This is how perfmon explains the terms: Working Set is the current size, in bytes, of the Working Set of this process. Private Bytes is the current size, in bytes, of memory that this process has allocated that cannot be shared with other processes. Not all parts of that huge address space are equal.
