Hi AllI'm investigating some performance issues on a 2003 server at the moment - the server is a file server, has 4GB of RAM & has more than 3GB free memory & is only using a tiny amount of its paging file (11-12 MB). However, the server is reporting high pages/sec values - often reaching 400-500+ pages/sec. The high paging activity often seems to be associated withone of theSVCHOST processes. The server is fairly well-used, but according to Spotlight, the only real area of concern is the high pages/sec value.Can anyone suggestreasons why thepages/sec value is so high if the free memory is high and swapfile usage is very low ?Usually for high paging, I'd add RAM but the amount of free memory seems fine & the swapfile is practically empty.Thanks !

Hi Technought,What is the version of that Windows Server 2003? is it 64bit version of Windows Server 2003?Generally speaking, the 64-bit versions of Microsoft Windows Server 2003 can support more RAM than the 32-bit version product. When lots of memory is added to a computer, a paging file may not be required. When you use the Pages/sec counter to measure paging file use, the value that is returned may not be accurate. To obtain an accurate measurement of paging file use, we may need touse other performance counters. We can use System Monitor measurements to calculate the size of the paging file that computer requires.For more detailed information, please refer to:How to determine the appropriate page file size for 64-bit versions of Windows Server 2003 or Windows XPhttp://support.microsoft.com/kb/889654Hope it helps.

High Pages/sec may be normal on systems that do a lot of memory-mapped file IO. You can check the Pages Output/sec counter to see if this is the case (it should be low if there are few pagefile writes).Pages Input/sec = paging reads from the pagefile or memory mapped filesPages Output/sec = paging writes to the pagefile only (writes to memory mapped files are not inluded here)Pages/sec = Pages Input/sec + Pages Output/sec

hi technought, good day..did you had a chance to went through the suggestions provided by david and pavel ?, if you need any further assistance on your query please feel free to re-post here .sainath !analyze
