Thanks Hamid,

I am using Windows Server 2003. I always want to improve performance. I am using Visual Studio 2005/2008 to develop C++ application.

What are the tools/experiences you had before?

regards,
George

Hi Hamid,

Thanks for sharing the information. If you are using Task Manager, I have a question, what means "PF" (in Windows Server 2003 Task Manager)? The same as physical memory?

George

This is form Task manager's help about PF Usage:
The amount of paging file being used by the system.

Thanks Hamid,

In my understanding, paging file is persistent storage for swapped out pages. Right?

Which parameter in Windows Server 2003 is used to monitor the real physical memory consumed?

George

At the Task Manager you have a section its name Physical Memory it has three options that first is total memory and second is available memory you can use of it,on the performance it has a counter that you can see free memory.(When windows doesnt has enough memory for runnig programs it uses of hard for it.)

Thanks Hamid,

I am using Windows Server 2003. There are three categories, total, available and System Cache. What is system Cache mean? Smile | :)

Thanks Hamid,

I like second link. The 3rd one is for Windows 2000, and I am using Windows Server 2003, do you have a link for Task Manager for Windows Server 2003?

Thanks Hamid,

I read it again. The links describes the differences between the content in System Cache between Windows Server 2000 and Windows NT 4.0. I am not sure how about Windows Server 2003? I have not found any information for Windows Server 2003, and if you have found any, it is appreciated if you could share with us. Smile | :)

SUMMARY
This article describes how Windows 2000 determines the amount of memory used for data caching.
MORE INFORMATION
When you use Task Manager to compare the performance of a Microsoft Windows NT 4.0-based computer to the performance of a similar Windows 2000-based computer, Windows 2000 Task Manager reports the amount of system cache memory in use, and Windows NT 4.0 Task Manager reports the amount of file cache memory in use. Also, the amount of memory used by the Windows 2000 system cache may be significantly larger than the amount of memory used by the Windows NT 4.0 file cache.

Because the Windows 2000 Task Manager System Cache field includes the size of the transition list, this field is a more accurate report of caching information. The transition list is memory which has been reclaimed by the operating system from working sets, including the file cache, memory that was used by programs, and other operating system memory usage. The transition list is not counted by Windows NT 4.0 File Cache.

The File Cache field only counts the size of the file cache working set, or that amount of memory which is currently in use by the cache manager. The File Cache field does not count the number of cached memory pages that are in transition.

For these reasons, the system cache entries in Windows 2000 Task Manager will appear larger than the Windows NT 4.0 Task Manager file cache counterpart. These differences do not indicate that a Windows 2000-based computer is using more system memory than a similar Windows NT 4.0-based computer.
