mount options when using direct i/o?

hi,

we're benchmarking the database of our application and are looking at direct i/o versus buffered i/o. From what I've read the parameter filesystemio_options is important - as are the parameters in mount options for the filesystem. can anyone point me towards a reference/document that discusses the relative merits of this feature and provides some information on a unix o/s variant basis regarding what can and cannot be done or set ?
