We have a exchange server that is setup as follows. The os and page file on c drive which is mirrored. the Database on raid 5 drives and the log files on a mirrored drive. I am seeing some performance issues with the paging file that does not seem related to memory and am wondering if it is the disk drives. I would like to move the page file to another drive and am thinking of moving it to the log file drive. Would this be ok? I have no more hard drives or I would put it on its own drive. Stupid question..Does the paging file write sequentially or randomly? I obviously would like to put it on a drive the read writes the same. Thanks in advance for your help.
