By this we mean a separate hard drive, not just another partition of the same hard drive. To solve the problem of hard faults, you may want to try moving a swap file – pagefile.sys – to another internal hard drive. You can solve the problem of hard faults and hard disk thrashing easily by having more RAM installed on your computer. If you have dozens of hard faults per second or even hundreds of hard faults per second, that’s too many of them, and you should be concerned for sure.Ī high number of hard faults and a high disk activity are often a consequence of not having enough RAM installed. The problem arises when you have too many programs running at the same time and when the programs read data to and from the hard disk on a continuous basis. This problem does not happen as regularly as it did in the past, but if you have an old computer with limited resources, which still runs on an older version of Windows such as Vista, hard faults can be a frequent occurrence. They were a problem in the past when PCs had limited memories and hard drive thrashing was a common occurrence because of issues with getting into the page file. Hard faults are not usual in today’s PCs that come with such large memories. This is a serious problem for the PC and could cause it to behave sluggishly. The hard drive though continues to run for as long as possible. When this happens often, this leads to a serious bout of hard disk thrashing and the program simply stops responding. When hard faults happen on a regular basis, they slow down the computer and lead to an overuse of the hard disk. When this happens the PC works harder looking for the memory on the hard disk. Hard faults are said to happen when an address in the memory of a program or that of a part of a program is not present in the main memory anymore, but has been swapped out to the paging file (hence the old name “page fault”). In the older versions of Windows, hard faults were called as page faults. Then you have every reason to be worried.īut what are hard faults anyway? And how many hard faults per second are too many? Is there a way to bring this number down? We discuss this and more in this article. It shows something called “hard faults/Sec”.ĭoes it show hundreds of hard faults per second? Pay attention to the section called “Memory”. Here, check the utilization rate in the CPU and the hard drive. Or open Reliability and Performance Monitor using the Administrative Tools from the Control Panel. Use IPHost Network Monitor to monitor your servers, domains, computers and devices.Has your PC been very slow lately? If you have tried everything you could and your PC still doesn’t show any sign of speeding up, you should try starting Windows Research Monitor using the Task Manager. IPHost Network Monitor is an advanced and easy tool for monitoring LAN and WAN networks, network servers, workstations and TCP/IP devices. Excessive paging, a symptom of a memory shortage, can cause delays which interfere with all system processes. Many of the memory counters monitor paging, which is the movement of pages of code and data between disk and physical memory. Virtual memory consists of the space in physical memory and on disk. Physical memory is the amount of random access memory on the computer. The Memory performance object consists of counters that describe the behavior of physical and virtual memory on the computer. However, hard faults, which require disk access, can cause significant delays. This counter includes both hard faults (those that require disk access) and soft faults (where the faulted page is found elsewhere in physical memory.) Most processors can handle large numbers of soft faults without significant consequence. It is measured in number of pages faulted per second because only one page is faulted in each fault operation, hence this is also equal to the number of page fault operations. Page Faults/sec is the average number of pages faulted per second. SELECT PageFaultsPersec FROM Win32_PerfFormattedData_PerfOS_Memory To create a WMI monitor for Page Faults Persec, provide host name (it must be a Windows host) and specify custom WQL query: With IPHost Network Monitor you can run WMI Page Faults Persec monitoring of various devices in your network.
