What determines system Page Size?

hi all, what actually determines the page or buffer size that the engine uses? i know it is directly related to the os and hardware(?). i thought that it had to do with the largest block size that could be transferred from a peripheral. so if the largest single transfer size that the os can handle from the disk is 2k, then that is the page size. am i anywhere close? enquiring minds want to know. mickm -- _____________________________________________________________________________ Mickey Mestel mickm@netcom.com -on a beach in thailand to a beautiful, stoned, norwegian woman: "..yeah, it's just another foreign country without ice." -----------------------------------------------------------------------------
