Modified Page List Bytes perf counter RRS feed

  • Question

  • Hi,

    I'm seeing an issue where large amounts of memory are showing used but not by any particular process. Checking the prime suspect application I can't see any memory leaks. However I do notice that the Modified Page List Bytes perf counter is running at a level corresponding to the "missing" memory.

     

    From research I can see that the counter is "Modified Page List Bytes is the amount of physical memory, in bytes, that is assigned to the modified page list. This memory contains cached data and code that is not actively in use by processes, the system and the system cache. This memory needs to be written out before it will be available for allocation to a process or for system use"

     

    However could someone please explain to me what this actually means ?

    Thanks
