What makes you think that the device driver isn't doing the same? The SCSI bus can handle multiple requests and have many requests outstanding: command tag queuing. I find it extremely hard to believe that Informix (or any other vendor s/w) could match the h/w vendor's *own* engineers. Furthermore you add an additional layer of software at the *user* level so you end up with less performance. But hey, if that's okay with you, go for it. I'm consistently amazed how many people swallow the "Informix Line" with no question: o what? support needs to dial in to fix my db? ahm, okay, I'll buy support. o what? informix knows the hardware better than HP/Sun/SGI's engineer's? oh, okay... -- Pablo Sanchez | Ph # (650) 933.3812 Fax # (650) 933.2821 pablo@sgi.com | Pg # (800) 930.5635 -or- pablo_p@pager.sgi.com ------------------------------------------------------------------------------- I am accountable for my actions. http://reality.sgi.com/pablo [ /Sybase_FAQ ]
