Windows 7 resource monitor hard faults




















Step 1. Step 2. Click on Advanced system settings option and navigate to the Advanced tab in the pop-up window. Step 3. Click on the Settings menu under the Performance section and navigate to the Advanced tab. Step 4. Click on the Changes menu under the Virtual Memory section.

Then unselect the checkbox for Automatically manage paging file size for all drives. Step 5. Select the drive that you want to disable the pagefile. Step 6. To find your Page file size in Windows 8, the instructions are similar to Windows 7. From here click the Advanced System Settings link. On the System Properties window that opens, make sure you are on the Advanced tab. In the Performance area click Settings. In the Performance Options window click the Advanced tab and there you should see a section labeled Virtual memory.

If you want to manually control your page file you can click the change button. Here Windows will make recommendations as to the size of your page file. Back when drives were mechanical there was a significant performance difference between using RAM and a hard drive. However, now that computers are more often being sold with solid state drives — SSDs, it is a good idea to let Windows manage the page file.

There is still a performance difference between memory and a SSD drive, but will generally not be noticeable to you. You can tell if you have a Solid State Drive by looking at the spec sheet for your computer or by examining your Device Manager.

The overview tab is a good starting point, as it gives you an overview of the resource usage. It highlights CPU and memory usage, disk utilization, and network use in real-time. Each particular listing offers a wealth of information. The CPU box lists process names and IDs, the network box IP addresses and data transfers, the memory box hard faults, and the disk box read and write operations.

One interesting option that you have right here and there is to select one or multiple processes under CPU to apply filters to the Disk, Network and Memory tab. If you select a particular process under CPU, Resource Monitor lists the disk, network and memory usage of that process only in its interface.

This is one of the differences to the Task Manager, as you cannot do something like that in the tool. You find the processes listing of the overview page there, and also the three new listings Services, Associated Handles and Associated Modules. You can filter by processes to display data only for those processes. This is quite handy, as it is a quick way to see links between processes, and services and other files on the system.

Note that the graphs are different to the ones displayed before. Associated Modules lists files such as dynamic link libraries that are used by a process. Associated Handles point to system resources such as files or Registry values. These offer specific information but are useful at times.

You can run a search for handles, for instance, to find out why you can't delete a file at that point in time. Resource Monitor gives you some control over processes and services on the CPU tab. Right-click on any process to display a context menu with options to end the selected process or entire process tree, to suspend or resume processes, and to run a search online. The Services context menu is limited to starting, stopping and restarting services, and to search online for information.

Processes may be displayed using colors. A red process indicates that it is not responding, and a blue one that it is suspended. The memory tab lists processes just like the CPU tab does, but with a focus on memory usage. It features a physical memory view on top of that that visualizes the distribution of memory on the Windows machine.

If this is your first time accessing the information, you may be surprised that quite a bit of memory may be hardware reserved. The graphs highlight the used physical memory, the commit charge, and the hard faults per second. Each process is listed with its name and process ID, the hard faults, and various memory related information. You get the same level of control in the right-click menu so that you can terminate any process using it. The Disk tab of the Windows Resource Monitor lists the disk activity of processes and storage information.

It visualizes the disk usage in total and for each running process. You get a reading of each processes' disk read and write activity, and can use the filtering options to filter by a particular process or several processes. The Storage listing at the bottom lists all available drives, the available and total space on the drive, as well as the active time.

The graphs visualize the disk queue length. The Network tab lists network activity, TCP connections and listening ports. It lists network activity of any running process in detail. This alone is useful, as it tells you right away if processes connect to the Internet.

You do get TCP connection listings that highlight remote servers that processes connect to, the bandwidth use, and the local listening ports. Some folks have reported inordinately huge amounts of memory being allocated to the Hardware Reserved list. While I haven't encountered this situation myself and can't verify the suggested solution, many have reported that upgrading the system BIOS firmware solved the problem.

The In Use list, shown in green in Figure C, represents the amount of memory being used by the operating system, drivers, and the various running processes. In Use memory is calculated by adding the sizes of the Modified, Standby, and Free values and subtracting this from the amount of recognized memory, which is listed as Total in the section just below the graph.

Shown in orange, the Modified list represents the pages of memory that contain data that has been modified but not been accessed for a while. As such it is not technically in use but can still be pulled into service quickly if needed. If memory in the Modified list has not been accessed in a long time, the memory manager will write the page to disk and then move it to the Standby list.

The Standby list, which is shown in blue, contains pages that have been removed from process working sets but are still linked to their respective working sets. As such, Standby list is essentially a cache. However, memory pages in the Standby list are prioritized in a range of , with 7 being the highest. Essentially, a page related to a high-priority process will receive a high-priority level in the Standby list.

For example, processes that are Shareable will be a high priority and pages associated with these Shareable processes will have the highest priority in the Standby list. Now, if a process needs a page that is associated with the process and that page is now in the Standby list, the memory manager immediately returns the page to that process' working set.

However, all pages on the Standby list are available for memory allocation requests from any process. When a process requests additional memory and there is not enough memory in the Free list, the memory manager checks the page's priority and will take a page with a low priority from the Standby list, initialize it, and allocate it to that process.

The Free list, shown in light blue, contains pages of memory that have not yet been allocated to a process or were previously allocated but returned to the memory manager when the process ended. While "not yet been allocated" and "previously allocated" memory both show in the Free part of this bar graph, the "not yet been allocated" pages are actually part of another list called the Zero Page list. These are so-called because they have been initialized to zero and are ready for use when the memory manager needs a new page.

Now that you have a good idea of how the memory manager in Windows 7 works on a global level, let's take a few minutes to discuss a common misconception with Windows 7's memory management scheme. As you can see in Figure C, Free memory is the second smallest list in the graph.

The misconception is to look at that small value and think that Windows 7 is a memory hog and that a system cannot run effectively when there is hardly any Free memory. But just the opposite is true, in the case of Windows 7's memory management scheme, Free memory is wasted memory.

The more memory that Windows 7 keeps in play, the better. By keeping memory full and juggling pages between the various lists along with using its Standby priority system, Windows 7 improves efficiency and does its best to keep memory pages from hitting the page file where Hard Faults and sluggish performance are more likely to occur. Do you want to see Windows 7's memory management scheme in action?
