See Subject and http://support.microsoft.com/kb/889654 (How to determine the appropriate page file size for 64-bit versions of Windows Server 2003 or Windows XP) I have a system equipped with 64GiB of RAM. Why does does SQL and MSDTC require this configuration? RAM sizes are increasing nowadays and the article also states "When lots of memory is added to a computer, a paging file may not be required.". I agree to that. Why should a machine with a few dozen Gigs of RAM require an even bigger pagefile? Swapping that much would decrease system performance so much that it imho would also affect system stability. Regards, Peter
