<snip> 

Finding out that the speed of a LTO3 3576 tape drive isn't any faster
than a LTO2 3582.  Both were fiber attached from 5704 cards via IBM
2109-F16 SAN switch.  Is there any option on SAVLIB that tells it to
shift gears?

Did you swap out the 5704s for 4Gb fibre?  Also the IOP and Buss
congestion has quite a bit to do with the speed.  I think your limit is
the interface cards.
