Del and/or Andy can probably answer this, hopefully in a way that a 
non-hardware/OS person, like me, can understand.

Our hardware guy upgraded a driver on my 6 AIX boxen.  As a result, my thruput 
went to hell, with backups running, not at Kb/s, but bits/s.  But not on 
clients with the MSSQL or ORACLE TDP, or SQL-Backtrack.  Those clients went 
thru at the expected rate.  My supposition is that clients using the API use a 
different I/O path than regular clients.

Enquiring minds want to know.
