>From the technote that Mark pointed you to:

"NOTE: For Digital Linear Tape (DLT) drives the number that seems to give the 
best performance for SIZE_DATA_BUFFERS is 65536. Further performance 
improvements can be achieved by increasing the value in the 
NUMBER_DATA_BUFFERS file."

My own testing confirms this in my environment.
