Not for the price of the product...

You haven't told us if you are checking for tape drive contention,
as in drives busy with higher priority tasks.
If no contention, you may have some "difficult" tapes, consuming costly
retries in reading or writing.  To try to isolate the problem, you can
do Move Data on indicative tapes and follow the progress, watching for
particular points where things crawl, and go from there, as in examining
I/O load or paging on your server.
We also don't know your tape technology type: as you may have seen from
historic posting, start-stop on some drives is painful.
