Pages sec file server

Privacy policy. A page file also known as a "paging file" is an optional, hidden system file on a hard disk. Page files enable the system to remove infrequently accessed modified pages from physical memory to let the system use physical memory more efficiently for more frequently accessed pages. Some products or services require a page file for various reasons. For specific information, check the product documentation.

A page file is required to make sure that the database cache can release memory if other services or applications request memory. Page files can be used to "back" or support system crash dumps and extend how much system-committed memory also known as "virtual memory" a system can support.

For more information about system crash dumps, see system crash dump options. When large physical memory is installed, a page file might not be required to support the system commit charge during peak usage. For example, bit versions of Windows and Windows Server support more physical memory RAM than bit versions support. The available physical memory alone might be large enough. However, the reason to configure the page file size hasn't changed.

It's peanuts. Is adding RAM difficult? But there is no one on site who has ever opened a computer, yet alone added memory. It isn't worth the risk quite frankly. Also, this isn't a matter of pinching pennies. We have three servers having performance issues. All servers that have gone out in the last 18 months have had at least 2GB of memory, but as I said, we have at least servers that are older then that in the field, and they only have 1GB, and in general we have had nary an issue to date.

Now if these three server's are doing something not normally done by our jobsite server's that may require more memory I have no problem arranging for the server to get it, but I don't have a lot of experience where it wasn't immediately obvious that the server needed more memory. That doesn't seem really like the values for a system that's memory constrained.

Then again, that's why I'm asking for help, I'm not well versed in this type of issue. But reading some of the links provided here doesn't seem to make me think adding memory will help.

Am I misinterpreting what perfmon is telling me? Could the remoteness of the servers have anything to do with this issue? This might explain why the problems seem to be coincidental with your Vista rollout. The solution is apparently to apply SP1, although a memory upgrade might also help somewhat.

It seems odd that they consider the fix for this to be Vista-side rather than I guess the reasoning is that it works for every other operation, so why putz with a working cache manager? Actually that's a very interesting link. We have no issues with random server performance on sites will with XP, and performance issues are ioften reported shortly after a site is converted to Vista.

It would certainly explain a possible tipping point for more memory being required with Vista systems versus XP on some of these sites. It's also something that can be easily explained to management and supported by MS documentation.

When available bytes are plentiful, the Virtual Memory Manager lets the working sets of processes grow, or keeps them stable by removing an old page for each new page added.

When available bytes are few, the Virtual Memory Manager must trim the working sets of processes to maintain the minimum required. Lack of enough PTEs can result in system wide hangs. Hard page faults occur when a process refers to a page in virtual memory that is not in its working set or elsewhere in physical memory, and must be retrieved from disk. When a page is faulted, the system tries to read multiple contiguous pages into memory to maximize the benefit of the read operation.

This counter is a primary indicator of the kinds of faults that cause system-wide delays. It includes pages retrieved to satisfy faults in the file system cache usually requested by applications non-cached mapped memory files.

Pool Paged Bytes is the size, in bytes, of the paged pool, an area of system memory physical memory used by the operating system for objects that can be written to disk when they are not being used. The Working Set is the set of memory pages touched recently by the threads in the process.

If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before leaving main memory. An instruction is the basic unit of execution in a processor, and a thread is the object that executes instructions.

Every running process has at least one thread. This counter indicates the rate at which bytes are sent and received over each network adapter. This counter helps you know whether the traffic at your network adapter is saturated and if you need to add another network adapter. How quickly you can identify a problem depends on the type of network you have as well as whether you share bandwidth with other applications.

Higher values indicate network bandwidth as the bottleneck. High values many not necessarily be bad. High levels of context switching can occur when many threads share the same priority level. This often indicates that there are too many threads competing for the processors on the system. If you do not see much processor utilization and you see very low levels of context switching, it could indicate that threads are blocked.

This value is an indirect indicator of the activity of devices that generate interrupts, such as network adapters.

A dramatic increase in this counter indicates potential hardware problems. This was a spike — not an average.
