Great. I guess the next step is to add selection criteria, otherwise a million Wikis will tell everyone to use '-aio linux' :-) Do you know what the selection criteria should be - or is there a document/paper somewhere which says (ideally from benchmarks)? I'm interested for an unrelated project using AIO - so I'm willing to help get this right to some extent. -- Jamie ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
