Do you know of a web site where I could research particular thought on? I have not seen anything like that in my research. Thanks.

In a UNIX system it is better to have more small size datafiles than a few or one large datafile: The reason is that UNIX aquires an exclusive file write lock and therefore if you use multiple files you will avoid a situation where multiple simultaneous writes to data files become serialized and consequently reduce I/O performance: For example instead of one 2GB Data file , split it into 8 250mb: By the way I am addressing OLTP type systems with this e-mail
