Try using the Disk tab in Resource Monitor to see what's accessing the disk so much.ītw, an often-overlooked cause of slow disk activity is disk errors, which result in retries. You mention that another view of Task Manager (which we can't see) seems to show that your disk 0 is busy a high percentage of the time. The paged and nonpaged pool also are part of the system-wide commit charge. You don't really have a problem with your commit charge, but for reference, I'll add: Each process's contribution to this is shown in TM's "Details" tab, "Commit size" column (which is not displayed by default you'll likely have to add it). So disabling your page file will not address your performance problems.Ĭommitted memory is created when processes allocate it. The graph on the memory page shows physical (RAM) memory usage and it shows only 30% of RAM in use. (Running into the commit limit brings you the "Windows is low on memory" pop-up.) See the numbers on your first Task Manager screen snapshot under "Committed"? The first shows how much is currently committed (the "commit charge") and the second shows the commit limit. And on the other hand, there are other uses of RAM besides committed memory. ![]() ![]() In effect it allows the modified page list to use less RAM to contain more stuff, at some cost in CPU time but with far greater speed than pagefile I/O (even to an SSD). So n GB of commit charge is not necessarily using n GB of RAM. Memory compression in Windows is done as an intermediate step, on pages that otherwise would be written to the pagefile. Your task manager screen snap shows that you have 2.2 GB of committed memory, aka "commit charge", with a commit limit of 16 GB.Ĭommitted memory is virtual address space, specifically process-private virtual address space, and it is pageable. You do not have 16 GB of committed memory.
